7-Chloro-4-cyclopentyl-2,3,4,5-tetrahydro-1,4-benzoxazepin-3-one CAS 1340964-18-2

Description

7-Chloro-4-cyclopentyl-2,3,4,5-tetrahydro-1,4-benzoxazepin-3-one (CAS 1340964-18-2), molecular formula C14H16ClNO2 and molecular weight 265.74 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, 7-Chloro-4-cyclopentyl-2,3,4,5-tetrahydro-1,4-benzoxazepin-3-one is typically off-white to pale yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 265.74 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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-4-cyclopentyl-2,3,4,5-tetrahydro-1,4-benzoxazepin-3-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.
