용도

4-(Trifluoromethyl)benzoic acid was used in the synthesis of salicylanilide 4-(trifluoromethyl)benzoates via N,N?-dicyclohexylcarbodiimide coupling in dry N,N-dimethylformamide. It was used as internal standard during the ultra trace analysis of fluorinated aromatic carboxylic acids by GC/MS method.

참고

Store in cool, dry conditions in a well sealed container. Store away from oxidizing agents.
