Chemical Structure
Description
The occurrence of (3-Methylthiophen-2-yl)methanesulfonamide is closely related to an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
(3-Methylthiophen-2-yl)methanesulfonamide (CAS 1248124-36-8), molecular formula C6H9NO2S2 and molecular weight 191.27 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (3-Methylthiophen-2-yl)methanesulfonamide (C6H9NO2S2) is characterized by an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
