Methyl 4-cyclopentyl-3-oxo-2,3,4,5-tetrahydrobenzo[f][1,4]oxazepine-7-carboxylate CAS 1708179-13-8 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 Methyl 4-cyclopentyl-3-oxo-2,3,4,5-tetrahydrobenzo[f][1,4]oxazepine-7-carboxylate.

Methyl 4-cyclopentyl-3-oxo-2,3,4,5-tetrahydrobenzo[f][1,4]oxazepine-7-carboxylate (CAS 1708179-13-8), molecular formula C16H19NO4 and molecular weight 289.33 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of Methyl 4-cyclopentyl-3-oxo-2,3,4,5-tetrahydrobenzo[f][1,4]oxazepine-7-carboxylate (C16H19NO4) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.

As a certified reference material (CRM), Methyl 4-cyclopentyl-3-oxo-2,3,4,5-tetrahydrobenzo[f][1,4]oxazepine-7-carboxylate 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.
