5-Butyl-4-chlorothiophene-2-carboxylic acid CAS 1399663-45-6

Description

Compared with other compounds in its class, the molecular weight of 218.70 g/mol gives 5-Butyl-4-chlorothiophene-2-carboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

5-Butyl-4-chlorothiophene-2-carboxylic acid (CAS 1399663-45-6) is a high-purity analytical reference standard with the molecular formula C9H11ClO2S and a molecular weight of 218.70 g/mol.

5-Butyl-4-chlorothiophene-2-carboxylic acid (C9H11ClO2S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
