Dihydromyrcene

Dihydromyrcene (CAS No. 2436-90-0) is a critical chemical intermediate. Buyers must prioritize purity levels (typically ≥95% or ≥99%) depending on the end-use. Key parameters include refractive index (1.441–1.448 at 20°C), specific gravity (0.770–0.790), and moisture content (<0.1%). For fragrance applications, the odor profile must be consistent, characterized by a fresh, citrusy, and lime-like scent without off-notes.

As a chemical substance, Dihydromyrcene must comply with REACH (Registration, Evaluation, Authorisation and Restriction of Chemicals) for the EU market. Suppliers should provide a comprehensive Material Safety Data Sheet (MSDS/SDS) and a Certificate of Analysis (COA) for every batch. If used in flavors or fragrances, ensure it meets IFRA (International Fragrance Association) standards and ISO 9001 quality management certifications.

Dihydromyrcene is primarily used as a precursor for Dihydromyrcenol, a staple in the perfume industry. It serves as a chemical intermediate in the synthesis of various aroma chemicals and specialty solvents. Its high volatility and refreshing scent make it ideal for use in household detergents, soaps, and fine fragrances, providing a clean, 'outdoor' freshness.

Dihydromyrcene is a flammable liquid and must be stored in a cool, well-ventilated area away from heat sources and oxidizers. Buyers should ensure the supplier uses epoxy-lined steel drums or ISO tanks to prevent contamination. The product has a typical shelf life of 12–24 months if kept in original sealed containers; therefore, checking the production date is vital for inventory turnover planning.

The primary risks include quality inconsistency and logistics delays. To mitigate these, always request a pre-shipment sample for lab testing. Utilize third-party inspection services (like SGS or BV) to verify the cargo at the loading port. For secure sourcing, platforms like Made-in-China.com offer verified supplier profiles and Audit Reports that help validate the manufacturer's production capacity and legal standing.

Dihydromyrcene is classified under UN 2319 (Terpene hydrocarbons, n.o.s.) or similar hazardous categories depending on the blend. It requires Class 3 Flammable Liquid packaging. Ensure the supplier is experienced in IMDG (International Maritime Dangerous Goods) regulations. You must confirm that your freight forwarder is licensed to handle dangerous goods (DG) and that the port of entry is equipped to receive such materials.

Chemical pricing is often tied to raw material costs (like turpentine oil) and crude oil indices. Negotiate based on volume-based pricing tiers; for example, purchasing in full container loads (FCL) can reduce unit costs by 10-15% compared to LCL. Discuss long-term supply contracts to hedge against price volatility and ensure a stable supply chain during peak seasons.

Avoid high-risk payment methods for initial orders. Use Letters of Credit (L/C) for large volumes to ensure payment is only released upon presentation of valid shipping documents. For smaller or trial orders, utilize the secured payment services provided by Made-in-China.com, which protect the buyer's funds until the receipt of goods is confirmed, significantly reducing the risk of fraud.
