5-(Benzenesulfonyl)-4-methyl-2,3,4,5-tetrahydro-1H-1,5-benzodiazepin-2-one CAS 866156-65-2 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 5-(Benzenesulfonyl)-4-methyl-2,3,4,5-tetrahydro-1H-1,5-benzodiazepin-2-one.

CATO supplies 5-(Benzenesulfonyl)-4-methyl-2,3,4,5-tetrahydro-1H-1,5-benzodiazepin-2-one (CAS 866156-65-2), a certified reference material (molecular formula C16H16N2O3S, MW 316.37 g/mol) for analytical method development and quality control.

5-(Benzenesulfonyl)-4-methyl-2,3,4,5-tetrahydro-1H-1,5-benzodiazepin-2-one (C16H16N2O3S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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.

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.
