Chemical Structure

(S)-1-amino-3-methyl-4,5-dihydro-1H-benzo[d]azepin-2(3H)-one (2R,3R)-2,3-bis(4-methylbenzoyloxy)succinate CAS 425386-58-9 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 (S)-1-amino-3-methyl-4,5-dihydro-1H-benzo[d]azepin-2(3H)-one (2R,3R)-2,3-bis(4-methylbenzoyloxy)succinate.

CATO supplies (S)-1-amino-3-methyl-4,5-dihydro-1H-benzo[d]azepin-2(3H)-one (2R,3R)-2,3-bis(4-methylbenzoyloxy)succinate (CAS 425386-58-9), a certified reference material (molecular formula C20H18O8C11H14N2O, MW 576.60 g/mol) for analytical method development and quality control.

The molecular framework of (S)-1-amino-3-methyl-4,5-dihydro-1H-benzo[d]azepin-2(3H)-one (2R,3R)-2,3-bis(4-methylbenzoyloxy)succinate (C20H18O8C11H14N2O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide 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. 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).

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.

As a certified reference material (CRM), (S)-1-amino-3-methyl-4,5-dihydro-1H-benzo[d]azepin-2(3H)-one (2R,3R)-2,3-bis(4-methylbenzoyloxy)succinate meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
