Procurement Report: 2-Amino-2-ethyl-1,3-propanediol (CAS No. 115-70-8)

1. Technical Specifications and Performance Metrics

Product Category: Specialty Amino Alcohol / Chemical Intermediate

Based on industry standards for high-purity amino alcohols, the procurement of 2-Amino-2-ethyl-1,3-propanediol (CAS 115-70-8) requires strict adherence to specific physical and chemical parameters to ensure efficacy in downstream applications.

• Purity Standards: The standard commercial grade for this compound is >98.0% (T) (Titration). For high-performance applications such as pharmaceutical synthesis or advanced polymerization, a purity range of 98.5% – 99.5% is typically targeted.
• Physical Appearance: The material is supplied as a White to Colorless to Yellow powder or solid. Procurement specifications should allow for a slight yellowing if the material is aged or exposed to light, provided the purity remains above the 98.0% threshold.
• Solubility Profile: This compound is highly soluble in water and alcohols, with moderate solubility in organic solvents. This makes it ideal for aqueous-based formulations.
• Molecular Properties:
  • Molecular Weight: ~133.17 g/mol
  • Functional Groups: Primary amine and two hydroxyl groups.
  • pH Behavior: Exhibits basic properties due to the amine group; typically used as a buffer or catalyst in pH-sensitive processes.

Actionable Recommendation: When issuing a Request for Quotation (RFQ), explicitly specify the required purity level (e.g., >98.0% vs. >99.0%) and request a Certificate of Analysis (CoA) that includes HPLC or Titration data. Do not accept materials with significant discoloration (dark yellow/brown) unless the supplier provides a specific stability justification, as this may indicate oxidation or impurities.

2. Industry Compliance and Quality Assurance

Procurement of industrial chemicals like CAS 115-70-8 must align with international quality management systems to mitigate supply chain risks and ensure regulatory compliance.

• Quality Management Systems (QMS): Reputable suppliers typically operate under ISO 9001 (Quality Management), ISO 17025 (Competence of Testing and Calibration Laboratories), and ISO Guide 34 (Reference Materials). These certifications ensure that the testing methods used to verify the >98.0% purity are internationally recognized and reproducible.
• Regulatory Status: While specific regulatory classifications (e.g., REACH, TSCA) depend on the jurisdiction of the buyer, the chemical is generally recognized as a standard industrial intermediate. However, it must be handled according to standard Safety Data Sheet (SDS) protocols for amines.
• Traceability: Suppliers with ISO 17025 certification provide traceable batch numbers and validated analytical methods, which is critical for industries like pharmaceuticals or cosmetics where batch consistency is mandatory.

Actionable Recommendation: Prioritize suppliers who can provide a current ISO 9001 and ISO 17025 certification number. Require that the CoA includes a specific reference to the testing standard used (e.g., USP, EP, or internal validated methods) to ensure the purity claim is verifiable. Avoid suppliers who cannot provide batch-specific analytical data.

3. Cost Efficiency and Integration Capabilities

Market Pricing & Volume:

• Typical B2B Price Range: Specialty amino alcohols of this purity generally range from $50 to $150 per kilogram depending on order volume and packaging. Small research quantities (grams) will carry a significantly higher unit cost (often $5–$10 per gram).
• Minimum Order Quantity (MOQ): Typical MOQs for bulk chemical procurement are 1 kg to 25 kg. Research-grade suppliers may offer 10g–100g samples.
• Lead Time: Standard lead times for in-stock inventory are 1–5 business days. For custom synthesis or out-of-stock items, expect 2–4 weeks.

Integration Capabilities:

• Formulation Compatibility: The compound integrates seamlessly into aqueous systems, making it ideal for immediate use in buffer preparation, corrosion inhibition, or as a monomer precursor without extensive pre-treatment.
• Storage Efficiency: As a stable solid powder, it offers high storage density compared to liquid reagents, reducing logistics costs per unit of active ingredient.

Actionable Recommendation: To optimize cost efficiency, consolidate orders to meet the 1kg+ MOQ threshold to avoid research-grade premiums. If your usage is intermittent, consider a "just-in-time" agreement with a supplier offering 5-day lead times to minimize inventory holding costs. Always request a tiered pricing schedule (e.g., 1kg, 10kg, 50kg) to identify the most cost-effective volume for your annual forecast.

4. Typical Use Cases

2-Amino-2-ethyl-1,3-propanediol is a versatile intermediate used across several high-value sectors:

1. Pharmaceutical Synthesis: Used as a building block for heterocyclic compounds and active pharmaceutical ingredients (APIs) due to its bifunctional nature (amine and alcohol groups).
2. Polymer Chemistry: Serves as a cross-linking agent or monomer in the production of polyurethanes and epoxy resins, contributing to enhanced thermal stability.
3. Corrosion Inhibition: Utilized in water treatment formulations and cooling systems to protect metal surfaces, leveraging its ability to chelate metal ions.
4. Cosmetics and Personal Care: Employed as a pH adjuster or buffering agent in hair care and skin care formulations where mild alkalinity is required.
5. Analytical Chemistry: Used as a standard reference material or buffer component in chromatography and titration processes.

Actionable Recommendation: Align your procurement volume with your primary application. If used for R&D (pharma/cosmetics), prioritize high purity (>99%) and small batch flexibility. If used for industrial scale (corrosion inhibitors/polymers), prioritize cost-effective bulk supply (>98%) and consistent batch-to-batch performance.

5. Long-Term Planning Considerations

Market Trends and Demand Signals:

• Growth in Green Chemistry: There is an increasing demand for amino alcohols that facilitate "greener" synthesis pathways, reducing the need for harsh catalysts. 2-Amino-2-ethyl-1,3-propanediol fits this trend due to its multifunctionality.
• Supply Chain Resilience: The market for specialty intermediates is subject to raw material volatility. Diversifying suppliers who hold ISO certifications helps mitigate the risk of quality drift during supply disruptions.
• Regulatory Tightening: Anticipated stricter regulations on amine-based compounds in wastewater and consumer products may drive demand for higher-purity grades to minimize byproduct formation.

Durability and Stability:

• Shelf Life: When stored in a cool, dry place away from light, the compound typically maintains stability for 24–36 months.
• Packaging: Ensure procurement of moisture-proof packaging (e.g., double-lined drums or high-density polyethylene bottles) to prevent hygroscopic degradation.

Actionable Recommendation: Develop a multi-sourcing strategy with at least two qualified suppliers holding ISO 9001/17025 certifications. Plan for a 12-month inventory buffer if the chemical is critical to your production line, as lead times can extend during peak industry demand. Monitor regulatory updates regarding amine emissions in your specific region to ensure future compliance.

6. Special Product Recommendations

The following table compares different grades and packaging options available for CAS 115-70-8 to assist in selecting the optimal product for your specific needs.

| Product Type | Best-Fit Buyer | Key Specs | Risk Check | Procurement Advice | | :--- | :--- | :--- | :--- :--- | | Research Grade | R&D Labs, Universities | Purity >99.0%, 10g–100g packs | High unit cost, limited shelf life | Buy small quantities for validation; verify CoA immediately upon receipt. | | Technical Grade | Industrial Manufacturing | Purity >98.0%, 1kg–25kg packs | Potential for batch variability | Request ISO 9001 certified supplier; demand batch-specific HPLC data. | | Reference Standard | Quality Control Labs | Certified >98.0%, Traceable to ISO Guide 34 | Low availability, high cost | Essential for calibration; only purchase from ISO 17025 accredited vendors. | | Bulk Drum | Large Scale Production | Purity >98.0%, 25kg+ drums | Logistics complexity, moisture risk | Ensure moisture-proof lining; verify nitrogen flushing if hygroscopic. |

Actionable Recommendation: For most B2B procurement scenarios, the Technical Grade in 1kg–10kg increments offers the best balance of cost and quality. Avoid "Research Grade" for production use due to cost inefficiency, and avoid bulk drums unless you have the storage infrastructure to prevent moisture absorption.

7. Frequently Asked Questions (FAQ)
