Chemical Structure
Description
The occurrence of Methyl 2-mercapto-4-methoxybenzoate is closely related to a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Methyl 2-mercapto-4-methoxybenzoate (CAS 104795-56-4), molecular formula C9H10O3S and molecular weight 198.24 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C9H10O3S, Methyl 2-mercapto-4-methoxybenzoate contains a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 198.24 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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).
