Import Benzotriazole — Buy in Bulk from Supplier in China

Benzotriazole (BTA) is an organic heterocyclic compound with formula C6H5N3, widely employed as a corrosion inhibitor and stabiliser in metalworking fluids, coolants, and photographic chemistry. Rugao Jinling Chemical Co., Ltd supplies this material as white crystals with minimum 99.8% assay, a melting point of at least 97.0 degrees C, and maximum moisture content of 0.08%. The batch from this Jiangsu-based supplier presents aqueous pH between 5.5 and 6.0, with ash content held to 0.01% maximum. Solubility is complete in alcohol with no insoluble residue, giving an approximately transparent solution.

The material exhibits solubility in alcohol, benzene, toluene, chloroform and DMF, with only slight solubility in water. In air it oxidises to a red colouration, and vacuum distillation carries explosive risk, a critical handling parameter for processors. These properties derive from the conjugated triazole ring system, which chelates metal ions at heteroatom coordination sites. Standard industrial grades for this commodity typically range from 99.5% to 99.9% purity, with pharmaceutical or electronic grades demanding tighter moisture and ionic specifications.

Primary applications include copper and brass corrosion inhibition in recirculating water systems, antifreeze formulations, and silver protection in photographic emulsions. Buyers span metal finishing operations, coolant blenders, photographic chemical manufacturers, and electronics plating facilities. Trade packaging from this supplier is 40 kg net fibre drums (12 MT per 20' FCL) or 20 kg net woven bags (15 MT per 20' FCL). Importers should confirm current availability, as the supplier shows zero response rate on platform signals.

Rugao Jinling Chemical Co., Ltd is located in Huangshi Town, Nantong, Jiangsu Province, postal code 226538, in eastern China's established chemical manufacturing corridor. The supplier carries an imported tier designation and harbour trust tier on platform records. The response rate stands at 0.00% with average response hours recorded as zero, indicating no verified engagement through platform messaging channels. No verification badges, trade assurance, or third-party audit data is present in the available profile.

The listing offers benzotriazole with disclosed assay, melting point, and moisture parameters, but omits information on production capacity, annual turnover, employee count, export licence specifics, or client references. The company profile does not state ISO certification, GMP compliance, or REACH registration status. Buyers should conduct independent due diligence on manufacturing site capabilities, quality management systems, and regulatory documentation before committing to volume orders.
