2-mercaptobenzimidazole is composed of a benzimidazole ring (nitrogen-containing heterocyclic) and a thiol group (-SH), with the thiol group attached to position 2 of the benzimidazole ring. White to light yellow crystalline powder. The pure substance is close to white. When exposed to air, it may be slightly yellow due to oxidation. Slightly soluble in water (solubility approximately 0.1g /L at 25℃), readily soluble in organic solvents such as ethanol, acetone, and dimethyl sulfoxide (DMSO);

SAFETY INFORMATION

PRODUCT USAGE

2-Mercaptobenzimidazole, with CAS No. 583-39-1 and chemical formula C₇H₆N₂S, appears as white to pale yellow crystalline powder, odorless, slightly soluble in water, and easily soluble in organic solvents such as ethanol and acetone. It has good antioxidant, anti-aging and metal protection properties. Its core application is in the rubber industry, serving as a rubber vulcanization accelerator and anti-aging agent, which can effectively increase the vulcanization speed of rubber, enhance the tensile strength and wear resistance of rubber products, and extend the service life of rubber. It is widely used in the production of natural rubber and synthetic rubber. At the same time, it can also be used as a metal corrosion inhibitor, which can form a protective film on the metal surface to prevent metal oxidation and rust; in the medical field, it can be used as an intermediate in organic synthesis for drug synthesis; in the dye industry, it is used to synthesize various functional dyes, and is a versatile functional chemical raw material in multiple fields.
