Methyldibromoglutaronitrile, often tagged under CAS 35691-65-7, gets used as a biocide and preservative in industrial and personal care applications. Its structure features a nitrile backbone, double bromine atoms, and methyl substitutions, offering strong antimicrobial action. Properties like a density around 2.25 g/cm3, clear to yellowish liquid form, and molecular formula C6H6Br2N2 set it apart from common alternatives. HS Code falls under 2926909090 for customs.
China stands as one of the principal suppliers. Most manufacturing bases in Jiangsu and Shandong provinces focus on scale production and factory-direct pricing, which controls costs for downstream users. Right now, raw material trends, clean energy transitions, and government policy around environmental standards affect price. Direct quote requests and CIF/FOB options from a top supplier in China usually deliver competitive deals, especially with MOQ as low as 1–25kg for lab use or up to several tons for industrial buyers. Quick inquiry channels and transparent SDS/MSDS documentation make the procurement process direct.
Methyldibromoglutaronitrile ranks as a hazardous chemical. Handling requires up-to-date MSDS and PPE—impervious gloves, goggles, ventilated storage—and only trained staff should manage the substance. Inhalation or skin exposure risks irritation, so factory settings often invest in engineered ventilation controls and eye-wash stations. Packaging usually comes in sealed HDPE or metal drums to prevent accidental spills or leaks. Most suppliers now align with REACH, ISO, SGS, and other quality certifications. Buyers in Europe often check for TDS, SDS, or batch COA to lock down traceability and compliance.
Methyldibromoglutaronitrile acts as a broad-spectrum preservative in paints, adhesives, metalworking fluids, and some personal care products like shampoos (now restricted in the EU). In my own experience managing production lines for coatings, only a small dose—often less than 0.2%—gets added to achieve the desired shelf life. Formulators appreciate its strength, though rising regulation means substitution remains under review for long-term sustainability and safety. Certifications like Halal, Kosher, and OEM support play a bigger role for personal care or export-bound finished goods.
Quality and price drive almost every industrial purchase. Asking for free sample vials before full batches lets buyers confirm actual performance and check physical standards. Most legitimate manufacturers supply up-to-date safety paperwork, batch analytics, and guarantee against contaminant risks. Packing and shipping routes matter too, as delays at port or errant labeling run the risk of customs hold-ups, especially given unique hazards codes. Staying ahead means working closely with a supplier who updates on China export policy changes, and one who offers flexible quote—CIF, FOB, or DDP on request.
With regulatory policy tightening, EU and US buyers must keep track of product compliance. Bans or strict limits on use in cosmetics, for example, force adaptation in formulation and procurement strategies. In my work, switching suppliers who proactively issue new technical data and offer direct lines to quality managers cuts both risk and overhead. Today’s market expects full transparency, third-party certification, and traceable batches—whether for small-liter research solution bottles or multi-ton factory shipments. Staying informed on new REACH updates and ensuring ongoing supply chain audits make a real difference in long-term success.
