5-Ethyl-4,5,6,7-tetrahydrobenzo[b]thiophene-2-carboxylic acid CAS 590355-40-1

Description

The occurrence of 5-Ethyl-4,5,6,7-tetrahydrobenzo[b]thiophene-2-carboxylic acid is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

5-Ethyl-4,5,6,7-tetrahydrobenzo[b]thiophene-2-carboxylic acid (CAS 590355-40-1) is a high-purity analytical reference standard with the molecular formula C11H14O2S and a molecular weight of 210.29 g/mol.

5-Ethyl-4,5,6,7-tetrahydrobenzo[b]thiophene-2-carboxylic acid (C11H14O2S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. Its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
