Chemical Structure
Description
N-2-Propen-1-yl-2-thiophenesulfonamide (CAS 140938-40-5), molecular formula C7H9NO2S2 and molecular weight 203.28 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of N-2-Propen-1-yl-2-thiophenesulfonamide (C7H9NO2S2) is characterized by an amide group, a sulfone group, a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
