Chemical Structure

O4-tert-butyl O3-methyl 1,4-oxazepane-3,4-dicarboxylate CAS 1374652-85-3 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 O4-tert-butyl O3-methyl 1,4-oxazepane-3,4-dicarboxylate.

CATO supplies O4-tert-butyl O3-methyl 1,4-oxazepane-3,4-dicarboxylate (CAS 1374652-85-3), a certified reference material (molecular formula C12H21NO5, MW 259.30 g/mol) for analytical method development and quality control.

Based on its molecular formula C12H21NO5, O4-tert-butyl O3-methyl 1,4-oxazepane-3,4-dicarboxylate contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 259.30 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).

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 O4-tert-butyl O3-methyl 1,4-oxazepane-3,4-dicarboxylate 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.
