7-chloro-9-methyl-2,3,4,5-tetrahydro-1-benzoxepin-5-one CAS 103501-83-3

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 7-chloro-9-methyl-2,3,4,5-tetrahydro-1-benzoxepin-5-one.

CATO supplies 7-chloro-9-methyl-2,3,4,5-tetrahydro-1-benzoxepin-5-one (CAS 103501-83-3), a certified reference material (molecular formula C11H11ClO2, MW 210.66 g/mol) for analytical method development and quality control.

7-chloro-9-methyl-2,3,4,5-tetrahydro-1-benzoxepin-5-one (C11H11ClO2) contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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 7-chloro-9-methyl-2,3,4,5-tetrahydro-1-benzoxepin-5-one 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.
