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 ethyl 4-oxoazepane-3-carboxylate;hydrochloride.
ethyl 4-oxoazepane-3-carboxylate;hydrochloride (CAS 198419-09-9) is a high-purity analytical reference standard with the molecular formula C9H15NO3HCl and a molecular weight of 221.68 g/mol.
The molecular framework of ethyl 4-oxoazepane-3-carboxylate;hydrochloride (C9H15NO3HCl) is characterized by an amide group, a carboxylic acid 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. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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 ethyl 4-oxoazepane-3-carboxylate;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.
