Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(3-((4-Chlorophenyl)sulfonyl)propanamido)-6-methyl-4,5,6,7-tetrahydrobenzo[b]thiophene-3-carboxamide.
CATO supplies 2-(3-((4-Chlorophenyl)sulfonyl)propanamido)-6-methyl-4,5,6,7-tetrahydrobenzo[b]thiophene-3-carboxamide (CAS 850023-30-2), a certified reference material (molecular formula C19H21ClN2O4S2, MW 440.96 g/mol) for analytical method development and quality control.
Owing to a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, chlorine substitution, 2-(3-((4-Chlorophenyl)sulfonyl)propanamido)-6-methyl-4,5,6,7-tetrahydrobenzo[b]thiophene-3-carboxamide is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 440.96 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
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.
