Sodium Trichloroacetate
Sodium trichloroacetate is the sodium salt of trichloroacetic acid, a saturated acyclic monocarboxylic acid with three chlorine substitutions. It falls under HTS 2915.40.50 as 'other' salts of trichloroacetic acid, distinct from specific esters or the pure acid. Commonly used in organic synthesis and as a herbicide intermediate.
Methyl Trichloroacetate
Methyl trichloroacetate is the methyl ester of trichloroacetic acid, featuring a saturated acyclic chain with three chlorine atoms on the carboxyl carbon. Classified in HTS 2915.40.50 as an 'other' ester of trichloroacetic acid, used primarily as a solvent and chemical intermediate.
Ethyl Trichloroacetate
Ethyl trichloroacetate, the ethyl ester of trichloroacetic acid, is a halogenated saturated acyclic monocarboxylic acid derivative. It qualifies for HTS 2915.40.50 as an 'other' ester, valued in pharmaceutical synthesis and as a reagent in organic reactions.
Isopropyl Trichloroacetate
Isopropyl trichloroacetate serves as the isopropyl ester of trichloroacetic acid, a key solvent in paint removers and polymer industry. Its classification under HTS 2915.40.50 reflects its status as an 'other' ester of a specifically named chlorocarboxylic acid.
Ammonium Trichloroacetate
