Description
TCI C1230 5-Chlorothiophene-2-carboxylic Acid is a versatile heterocyclic building block bearing both a carboxylic acid group and a chlorine substituent on the thiophene ring. The acid function is readily converted into amides, esters, or acid chlorides using standard coupling conditions. The 5-chloro position offers a useful handle for transition-metal-catalysed cross-coupling and further functionalisation. Available in 5 g and 25 g packs, it is intended for professional laboratory use in line with the official TCI safety data sheet.
