Chemical Structure
Description
CATO supplies 5-Chloro-2-hydroxy-N-methyl-N-(thiophen-3-ylmethyl)benzamide (CAS 1043112-32-8), a certified reference material (molecular formula C13H12ClNO2S, MW 281.76 g/mol) for analytical method development and quality control.
The molecular framework of 5-Chloro-2-hydroxy-N-methyl-N-(thiophen-3-ylmethyl)benzamide (C13H12ClNO2S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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.
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.
