Methyl 2-(thian-4-ylidenE)acetate (CAS 62702-81-2) is a high-purity analytical reference standard with the molecular formula C8H12O2S and a molecular weight of 172.24 g/mol.
Methyl 2-(thian-4-ylidenE)acetate (C8H12O2S) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. 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).
CATO manufactures Methyl 2-(thian-4-ylidenE)acetate under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
