| Message: | 5-Bromothiophene-3-carboxylic acid CAS:100523-84-0 is synthesized by bromination of thiophene-3-carboxyic acid CAS:88-13-1, regioselectively. Functionalization at 5-position of thiophene-3-carboxyic acid produce very useful intermediate, 5-substituted thiophene-3-carboxylic acid, which could be used to attach moiety of 2-substituted thiophene-4-carboxylic acid.
5-Bromothiophene-3-carboxylic acid CAS:100523-84-0 is shown off-white powder with molecular formula (C5H3BrO2S). Its solubility in most polar organic solvent is very good.
2,5-Dibromothiophene-3-carboxylic acid CAS:7311-70-8 is twins of 5-Bromothiophene-3-carboxylic acid when bromination of thiophene-3-carboxylic acid. But both chemicals are available in pure form from UCHEM. url:http://www.uchemchemicals.com |
