3. Cost Efficiency and Integration Capabilities

The cost of Aluminium chloride is influenced by raw material volatility, packaging requirements, and the scale of the order. While the chemical itself is a commodity, the specialized packaging (glass ampules vs. bulk metal drums) significantly impacts the unit price.

• Typical B2B Pricing Range: $50 – $150 per kg for small volumes (gram to kilogram scale); bulk pricing (tonnage) is typically negotiated on a case-by-case basis, often ranging from $2,000 – $4,000 per metric ton depending on purity and packaging.
• Minimum Order Quantity (MOQ):
  • Small Scale: 10g – 100g (Glass ampules).
  • Medium Scale: 1kg – 10kg (Bottles).
  • Bulk Scale: 25kg – 1,000kg (Metal drums/bubblers).
• Lead Time: Typically 5 – 10 business days for standard stock items; 15 – 25 business days for custom bulk orders or specific purity grades.
• Integration: Compatible with standard chemical handling infrastructure but requires corrosion-resistant storage (stainless steel or lined containers) and dry nitrogen atmospheres.

Procurement Recommendation: To optimize cost efficiency, consolidate orders to meet bulk thresholds (e.g., 25kg+) to reduce per-unit packaging costs. For R&D phases, utilize small ampule quantities to minimize waste, but transition to bulk metal drums for production to lower the cost per gram. Always request a tiered pricing schedule from suppliers like Ereztech to leverage volume discounts.

4. Typical Use Cases

Aluminium chloride serves as a fundamental reagent in several high-volume industrial sectors. Its primary function is as a Lewis acid catalyst.

• Friedel-Crafts Reactions: Essential for alkylation and acylation of aromatic compounds in the production of dyes, fragrances, and pharmaceuticals.
• Petroleum Refining: Used in alkylation processes to produce high-octane gasoline components.
• Water Treatment: Employed as a coagulant and flocculant agent to remove suspended solids and phosphates from wastewater.
• Polymerization: Acts as a catalyst in the production of synthetic rubber and polyethylene.
• Organic Synthesis: Used in the synthesis of various intermediates for the fine chemical industry.

Procurement Recommendation: Align procurement specifications with the intended application. For water treatment, technical grade (lower purity) may suffice, reducing costs. For pharmaceutical or fine chemical synthesis, demand analytical grade (99.9%+) with strict heavy metal limits. Ensure the supplier can provide documentation verifying the absence of specific contaminants relevant to your downstream process.

5. Long-Term Planning Considerations

The market for Aluminium chloride is driven by the demand for petrochemicals and fine chemicals. Procurement strategies must account for supply chain volatility and safety regulations.

• Market Trends: Increasing demand in the petrochemical sector for alkylation catalysts and the expansion of the pharmaceutical industry are driving steady demand.
