Chemical Structure

Ethyl 1,4-oxazepane-7-carboxylate CAS 2090935-50-3 chemical structure

Description

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.

Ethyl 1,4-oxazepane-7-carboxylate (CAS 2090935-50-3) is a high-purity analytical reference standard with the molecular formula C8H15NO3 and a molecular weight of 173.21 g/mol.

Ethyl 1,4-oxazepane-7-carboxylate (C8H15NO3) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

As a certified reference material (CRM), Ethyl 1,4-oxazepane-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.
