Benzonitrile, 4-Mercapto-, often recognized under its CAS number 13958-21-7, plays a crucial role in specialty synthesis across the pharmaceutical and agrochemical sectors. Its unique molecular formula, C7H5NS, places it as a valuable intermediate. The molecular structure allows for versatility in organic synthesis projects. Properties like specific density near 1.18g/cm3 and appearance as a pale yellow solid or crystalline powder mean it stores and handles easily with standard procedures, provided appropriate hazardous material management is in place.
Identifying the right HS code helps streamline customs documentation and regulatory inquiries. For Benzonitrile, 4-Mercapto-, the common code lands within 2926909090, under organic nitrile derivatives. This detail proves important for trading companies and logistics partners working on CIF and FOB shipments out of China or other manufacturing hubs.
Safe handling matters. Material supplied from Chinese factories typically arrives with MSDS, SDS, and TDS documentation, required for REACH compliance and international chemical transport. Benzonitrile, 4-Mercapto- brings hazards typical of nitriles and mercaptans, like skin and eye irritation or toxic fumes under heat. Laboratories and purchasing managers should expect clear hazard and handling labelling, backed by ISO and SGS certification.
China remains the dominant global source for Benzonitrile, 4-Mercapto-. The local supply chain, with its established chemical companies and efficient manufacturing processes, makes the region attractive for bulk purchasers. Pricing reflects raw material costs, channel efficiency, and batch order size. Minimum Order Quantities (MOQs) often start as low as one kilogram for research, while industrial users typically negotiate by tonnage, often benefitting from significant discounts at higher volumes.
On inquiry, expect CIF (Cost, Insurance, Freight) and FOB (Free On Board) terms. Quotes often include options for OEM, with customization backed by batch-to-batch consistency certifications—important for regulated markets. Safe and prompt shipment, both standard and temperature-controlled, comes as industry norm. Samples are frequently available at no charge for preliminary quality checks, especially for new buyers exploring alternative suppliers or evaluating cost structures.
Benzonitrile, 4-Mercapto- functions in pharmaceutical building blocks, agricultural experiments, and specialty polymer projects. Some companies use it in synthesis of nucleophilic reagents and ligands due to the reactivity of its thiol group. Local regulations around hazardous material apply, including requirements for proper labeling, secure transport, and storage in ventilated, cool conditions. As a user, obtaining the full Safety Data Sheet (SDS) and Technical Data Sheet (TDS) proves essential before proceeding.
Manufacturers meeting ISO 9001, REACH, and SGS standards build trust, signaling a commitment to product safety and consistency. Some sources can provide halal or kosher certification if end-product applications require compliance for food or specialty pharma.
Direct factory purchase ensures a competitive price and reliable after-sales support. Buyers typically send inquiries specifying quantity, documentation needs, and required certifications. Reputable suppliers confirm order details, ship with full regulatory paperwork, and provide traceability—including batch numbers and test results. Custom solutions—including liter solution formulations or special delivery points—can be negotiated for recurring or high-volume buyers.
Staying updated on import news, policy shifts, and raw material price changes makes a real difference, especially for procurement leaders and researchers. The right supplier should keep you in the loop, providing transparent updates as part of a long-term partnership.
