Isoamyl alcohol

Buyers must prioritize purity levels, typically requiring ≥99% for pharmaceutical or analytical grades. Key parameters include the refractive index (1.405–1.410), boiling point (approx. 131°C), and moisture content (water <0.2%). For the fragrance and flavor industry, ensure the product is FCC (Food Chemicals Codex) grade and possesses the characteristic mild pear-like odor without off-notes.

As a hazardous chemical, it must have a valid SDS (Safety Data Sheet) compliant with GHS (Globally Harmonized System). For food-related applications, ISO 22000 or HACCP certifications are essential. If exporting to the EU, ensure the supplier is REACH registered; for the US market, compliance with TSCA (Toxic Substances Control Act) is required.

It is widely used as a solvent for fats, resins, and alkaloids, and as a key intermediate in the production of Isoamyl Acetate (banana oil). In the pharmaceutical sector, it serves in DNA extraction (phenol-chloroform method) to reduce foaming. Functional performance depends on its miscibility with organic solvents and its low solubility in water, which is critical for liquid-liquid extraction processes.

Evaluate the supplier's production capacity (annual tonnage) to ensure they can handle scaling. Bulk purchasing in 160kg-200kg drums or ISO tanks typically reduces unit costs by 15-25% compared to smaller carboys. Always request a COA (Certificate of Analysis) from the specific production batch to ensure consistency, as variations in isomers can affect downstream chemical reactions.

Isoamyl Alcohol is classified as a Class 3 Flammable Liquid (UN1105). It requires UN-approved packaging and must be handled by logistics providers certified for Dangerous Goods (DG). Ensure the bill of lading correctly reflects the Hazard Class and Packing Group (usually PG III) to avoid customs seizures or heavy fines at international ports.

Utilize secure payment methods and consider third-party pre-shipment inspections (such as SGS or Intertek) to verify quantity and chemical purity. When sourcing via Made-in-China.com, prioritize Audited Suppliers who have undergone on-site verification of their manufacturing facilities and business licenses to ensure they are legitimate chemical producers rather than unauthorized traders.

Monitor the price of raw materials like fusel oil or petroleum-based feedstocks. Negotiate based on formula-based pricing for long-term contracts or seek spot-price discounts during periods of high inventory. Requesting a tiered pricing structure based on volume (e.g., 5 tons vs. 20 tons) is a standard industry practice to optimize procurement costs.

Be aware of Anti-Dumping Duties (ADD) that may apply between specific country pairs. Ensure the HS Code (typically 2905.19) is accurately declared to prevent delays. Additionally, verify if the destination country requires a Chemical Import License or specific environmental declarations regarding VOC (Volatile Organic Compound) emissions.
