Chemical Structure
Description
2-methyl-3,4-dihydro-2H-1-benzothiopyran-4-one (C10H10OS) contains sulfur-containing functionality, a hydroxyl group, an ether linkage, an aromatic ring system. Its high carbon-to-hydrogen ratio confers good lipid solubility; 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).
2-methyl-3,4-dihydro-2H-1-benzothiopyran-4-one (CAS 826-86-8) is a high-purity analytical reference standard with the molecular formula C10H10OS and a molecular weight of 178.25 g/mol.
