1H-Benzotriazole is an anticorrosive agent, which is useful in aircraft deicing and antifreeze fluids. It is also employed in dishwasher detergents. Further, it is used as a restrainer in photographic emulsions and also useful as a reagent for the determination of silver in analytical chemistry. It also serves as a corrosion inhibitor in the atmosphere and underwater. Further, it is utilized in the synthesis of amines from glyoxal.
The combination with thionyl chloride (1:1), dissolved in DCM, is a useful and convenient reagent for conversion of alcohols and carboxylic acids to the alkyl or acyl chlorides: Synlett, 1763 (1999).
