Chemical Structure
Description
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.
CATO supplies (S)-3-Amino-1-methyl-1,3,4,5-tetrahydro-2H-benzo[b]azepin-2-one hydrochloride (CAS 958075-69-9), a certified reference material (molecular formula C11H14N2OHCl, MW 226.70 g/mol) for analytical method development and quality control.
The molecular framework of (S)-3-Amino-1-methyl-1,3,4,5-tetrahydro-2H-benzo[b]azepin-2-one hydrochloride (C11H14N2OHCl) is characterized by a nitrogen-containing heterocyclic scaffold, an amide 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
As a certified reference material (CRM), (S)-3-Amino-1-methyl-1,3,4,5-tetrahydro-2H-benzo[b]azepin-2-one hydrochloride 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.
