Source Daminozide Plant Growth Regulator for Storage, Germination, and Growth

Strategic Sourcing Guide for Daminozide Plant Growth Regulators

Understanding the Chemical Profile and Functional Classification

Daminozide, widely recognized in agricultural trade by its trade names such as Alar, B9, and B-Nine, serves as a critical synthetic plant growth regulator (PGR). When sourcing this material, buyers must first distinguish between its dual functional classifications observed in the market: it acts as both a growth promoter and a growth inhibitor or retardant depending on the specific application and dosage. The chemical identity is defined as N-Dimethylamino Succinamic Acid, with the molecular weight recorded at 160.17. Physically, the raw material typically presents as a white or light yellow powder, characterized by high water solubility, which allows for easy dissolution in water for foliar or soil applications.

The physical properties of the substance are consistent across most commercial listings. The melting point is generally observed within the range of 154-158°C, indicating a stable crystalline structure at standard ambient temperatures. For quality assurance, buyers should verify that the loss on drying does not exceed 0.50% and that water-insoluble matter remains at a maximum of 0.1%. These specific parameters are essential for ensuring the purity of the active ingredient before it enters the formulation stage. The substance is often categorized under the broader umbrella of plant hormones, specifically functioning to manipulate the dormancy cycles of storage organs, promote germination, and regulate the balance between vegetative and reproductive growth.

Technical Specifications and Formulation Standards

When evaluating product listings for Daminozide, the technical specifications vary significantly based on the intended formulation. The market offers the active ingredient in various concentrations, primarily identified as 85% TC (Technical Concentrate), 92% TC, and 95% TC. Additionally, formulated products are frequently available as 4% EC (Emulsifiable Concentrate), 10% SP/B (Soluble Powder), and 20% SP/TB. The choice between a technical concentrate and a formulated product depends on the buyer's downstream manufacturing capabilities or direct application needs.

The following table outlines the common specification variations observed in the supply chain:

Buyers must verify the specific product model against these standards. For instance, a listing labeled "85%SP" implies a specific solubility profile distinct from a "95%TC" listing. The packaging standards also vary; technical concentrates are often shipped in 25kg drums or 1kg aluminum foil bags to prevent moisture absorption, while liquid formulations may be packaged in 200-liter plastic or iron drums. It is crucial to confirm that the packaging material matches the chemical state of the product, as moisture sensitivity can degrade the efficacy of the powder forms.

Regulatory Compliance and Certification Verification

The procurement of Daminozide requires a rigorous approach to compliance, particularly given its history as a regulated substance in various jurisdictions. While the supplied data indicates the product originates from China, with specific production capacity noted at 200 tons per month in regions like Henan, buyers must independently verify the regulatory status of the specific batch or supplier. The chemical is identified by the CAS number 1596-84-5, a critical identifier for customs and regulatory documentation.

Buyers should not assume that a supplier's claim of "Growth Promoter" or "Growth Retardant" automatically implies compliance with the destination country's agricultural regulations. In many markets, the use of Daminozide is restricted or banned due to historical concerns regarding its metabolites. Therefore, the primary compliance check involves confirming whether the specific concentration and application method are legal in the target market. Suppliers may list keywords such as "B995" or "Alar Plant Growth Regulator," but these marketing terms do not constitute legal clearance.

Furthermore, certification checks should focus on the manufacturing facility's adherence to Good Manufacturing Practices (GMP) and the availability of a Certificate of Analysis (CoA) for every batch. The CoA must explicitly state the purity levels, such as the 85% or 92% TC specifications, and confirm that impurities like water-insoluble matter are within the 0.1% maximum limit. Without a valid CoA and clear regulatory clearance for the destination country, the procurement of Daminozide carries significant legal and operational risk.

Cost Drivers and Pricing Dynamics

The pricing of Daminozide is influenced by several factors, including the concentration of the active ingredient, the form of the product (TC vs. SP vs. EC), and the scale of the order. The observed price range in the market spans from 1 to 120 USD, though this wide variance often reflects differences in packaging, concentration, and the inclusion of formulation costs rather than the base price of the raw chemical alone. Higher concentrations like 95% TC typically command a different price point compared to lower concentration formulations like 4% EC, which include additional solvents and emulsifiers.

Minimum Order Quantities (MOQ) are a significant cost driver, ranging from 1 unit to 1000 units depending on the supplier's capacity and the product type. Some listings indicate a specific MOQ of 25kg, which is standard for bulk technical concentrates, while others may offer smaller sample quantities for testing purposes. Buyers should be aware that smaller orders often carry a higher unit cost due to the fixed costs of packaging and logistics. Additionally, the production capacity of 200 tons per month suggests that large-volume buyers may have leverage in negotiating terms, whereas smaller buyers may face stricter MOQs or longer lead times.

Typical Applications and Agronomic Benefits

Daminozide is utilized across a diverse range of agricultural applications due to its multifaceted effects on plant physiology. Its primary functions include prolonging the dormancy of storage organs, which is beneficial for the storage of fruits and vegetables, and breaking dormancy to promote germination. In terms of vegetative growth, it acts as a retardant, restraining the growth of stems, leaves, and buds, which helps in creating compact, sturdy plants less prone to lodging.

The product also plays a vital role in reproductive management. It can promote flower bud formation in some contexts while inhibiting it in others, allowing growers to manipulate flowering times. Specific agronomic benefits include promoting the formation of blossoms and fruits, thinning of blossoms and fruits to improve quality, and enhancing fruit coloring. Furthermore, Daminozide is known to improve the nutritional profile of crops by increasing amino acid content, raising protein levels, and boosting sugar content, which directly impacts the taste and market value of the produce.

The versatility of the product is evident in its ability to hasten rooting and promote overall plant growth when used at appropriate dosages. However, the dual nature of its action—promoting growth in some aspects while retarding it in others—requires precise application. Buyers sourcing this product for formulation should ensure that their technical teams understand these nuances to create effective final products that deliver the intended agronomic results without causing phytotoxicity.

Supplier Evaluation and Quality Control Protocols

Selecting a reliable supplier for Daminozide involves more than just comparing prices; it requires a thorough evaluation of the supplier's technical capabilities and quality control systems. Given that the product originates from China, with specific mentions of production in Henan, buyers should verify the supplier's production capacity and consistency. A stated capacity of 200 tons per month indicates a substantial operation, but buyers must confirm if this capacity is dedicated to Daminozide or if it is shared with other products, which could impact supply stability.

Quality control is paramount. Buyers should insist on pre-shipment samples, such as the "Daminozide B9" sample mentioned in some listings, to verify the physical appearance, solubility, and purity before committing to a large order. The sample should be tested against the standard specifications: melting point of 154-158°C, loss on drying ≤0.50%, and water-insoluble matter ≤0.1%. Additionally, the storage conditions provided by the supplier, such as "Keep in Cool and Dry Place" with a shelf life of 2 years, must be adhered to strictly to maintain product integrity.

When evaluating suppliers, buyers should also assess their customization capabilities. Many listings indicate that customization is available, which is crucial for buyers looking for specific concentrations or packaging formats. However, this customization must be backed by rigorous quality assurance to ensure that the final product meets the agreed-upon standards. The supplier's ability to provide detailed documentation, including batch-specific CoAs and compliance certificates, is a strong indicator of their reliability.
