Chemical Structure
Description
Owing to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system, 4-Mercaptophenylbutyric Acid is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 196.27 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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).
4-Mercaptophenylbutyric Acid (CAS 359436-81-0) is a high-purity analytical reference standard with the molecular formula C10H12O2S and a molecular weight of 196.27 g/mol.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
