4-HB-MTS 4-Hydroxybenzyl Methanethiosulfonate 491868-12-3 Methanesulfonothioic Acid (4-Hydroxyphenyl)methyl Ester (CAS 491868-12-3) is a high-purity analytical reference standard with the molecular formula C8H10O3S2 and a molecular weight of 218.29 g/mol.
4-HB-MTS 4-Hydroxybenzyl Methanethiosulfonate 491868-12-3 Methanesulfonothioic Acid (4-Hydroxyphenyl)methyl Ester (C8H10O3S2) contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. It is notably hygroscopic, 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.
