1,2,3,5-Tetrahydrobenzo[e][1,4]oxazepine hydrochloride (CAS 4029-37-2) is a high-purity analytical reference standard with the molecular formula C9H11NOHCl and a molecular weight of 185.65 g/mol.
The molecular framework of 1,2,3,5-Tetrahydrobenzo[e][1,4]oxazepine hydrochloride (C9H11NOHCl) 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 the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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 manufactures 1,2,3,5-Tetrahydrobenzo[e][1,4]oxazepine hydrochloride under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
