Acetyl chloride

Acetyl Chloride is a highly reactive organic compound, typically required at a purity level of ≥99.0% for industrial and pharmaceutical applications. Buyers must verify the refractive index (1.388-1.390) and boiling point (52°C) to ensure chemical integrity. It is critical to check for low impurity levels, specifically limiting free phosphorus or acetic acid content, as these can interfere with sensitive acylation reactions.

It is predominantly used as an acylation agent in the synthesis of pharmaceuticals (such as aspirin and acetaminophen), agrochemicals, and dyes. In the chemical industry, it serves as a vital intermediate for producing acetic anhydride and various organic esters. Due to its high reactivity, it is also used in laboratory reagents for testing cholesterol and water content in organic liquids.

As a hazardous chemical (Class 3 Flammable Liquid, Class 8 Corrosive), it must be accompanied by a comprehensive Material Safety Data Sheet (MSDS/SDS). Suppliers should hold ISO 9001 for quality management and ISO 14001 for environmental standards. For international trade, ensure the product complies with REACH (EU) or TSCA (USA) regulations, and that the packaging meets UN-certified standards for dangerous goods.

Acetyl Chloride reacts violently with water and moisture to produce hydrogen chloride gas. Therefore, you must prioritize suppliers who provide hermetically sealed, moisture-proof packaging, such as glass-lined steel drums or specialized plastic-lined iron drums. Ensure your logistics provider is equipped to handle corrosive and volatile substances in a temperature-controlled or well-ventilated environment.

Always utilize Trade Assurance or secure payment terms to protect your capital. Conduct thorough background checks on suppliers via Made-in-China.com to verify their 'Audited Supplier' status. It is highly recommended to appoint a third-party inspection agency (like SGS or BV) to perform a pre-shipment analysis of the chemical purity and packaging integrity.

This product is classified under UN Number 1717. You must ensure the supplier provides a Dangerous Goods Declaration and uses specialized 'DG' (Dangerous Goods) containers. Shipping routes should avoid excessive heat, and you must confirm that the destination port is authorized to receive Class 3/8 hazardous materials to avoid costly customs delays or rejections.

Price is often tied to the cost of raw materials like glacial acetic acid and phosphorus trichloride. Negotiate based on volume-based tiers; for example, purchasing in full container loads (FCL) can reduce unit costs by 10-20%. Additionally, discuss long-term supply contracts to hedge against market price volatility in the chemical sector.

Acetyl Chloride can sometimes be monitored under precursor chemical regulations depending on the jurisdiction. Verify if an Export License is required from the origin country and if an Import Permit is needed for your specific region. Ensure all customs documentation accurately reflects the HS Code (typically 291590) to prevent legal complications.
