2-mercaptobenzimidazole usage and synthesis

chemical properties	yellow or white crystals
usage	an antidegradant, protecting rubber from oxidation. an intermediate in the synthesis of rabeprazole (r070500)
general description	white to yellow crystals or cream colored powder. slight odor.
air & water reactions	dust explosion: 0.140 oz/ft3. insoluble in water. 2-mercaptobenzimidazole is moisture sensitive. .
reactivity profile	an organosulfide and an amine. organosulfides are incompatible with acids, diazo and azo compounds, halocarbons, isocyanates, aldehydes, alkali metals, nitrides, hydrides, and other strong reducing agents. reactions with these materials generate heat and in many cases hydrogen gas. many of these compounds may liberate hydrogen sulfide upon decomposition or reaction with an acid. amines are chemical bases. they neutralize acids to form salts plus water. these acid-base reactions are exothermic. the amount of heat that is evolved per mole of amine in a neutralization is largely independent of the strength of the amine as a base. amines may be incompatible with isocyanates, halogenated organics, peroxides, phenols (acidic), epoxides, anhydrides, and acid halides. flammable gaseous hydrogen is generated by amines in combination with strong reducing agents, such as hydrides.
fire hazard	flash point data for 2-mercaptobenzimidazole are not available; however, 2-mercaptobenzimidazole is probably combustible.
