3-Thiophenezoic acid Usage And Synthesis

Description

3-Thiophenezoic acid is a polymer monomer that can be used to synthesise thiophene derivative polymers, such as the poly(3-thiophene benzoic acid) (PTPA), the copolymer of 3-bromothiophene (BTP) and 3-thiophenezoic acid (TPA). These compounds are an important class of conductive polymers, typically exhibiting favourable electrochemical activity, environmental stability, and ease of processing.

Chemical Properties

white to light yellow crystal powder

Uses

3-Thiophenecarboxylic Acid was used as a lading compound for the development of a clinic useful D-amino acid inhibitor and have the potential to sever as active site proves to elucidate the structure-function relationships of D-amino acids.
