Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 3-methyl-2-sulfanylbenzoic acid.
3-methyl-2-sulfanylbenzoic acid (CAS 77149-11-2), molecular formula C8H8O2S and molecular weight 168.21 g/mol, is a CATO reference standard with documented purity and traceability.
3-methyl-2-sulfanylbenzoic acid (C8H8O2S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
