Chemical Structure

Ethyl (2Z)-2-azepan-2-ylidene-3-oxobutanoate CAS 72611-25-7 chemical structure

Description

The occurrence of Ethyl (2Z)-2-azepan-2-ylidene-3-oxobutanoate is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

CATO supplies Ethyl (2Z)-2-azepan-2-ylidene-3-oxobutanoate (CAS 72611-25-7), a certified reference material (molecular formula C12H19NO3, MW 225.28 g/mol) for analytical method development and quality control.

Ethyl (2Z)-2-azepan-2-ylidene-3-oxobutanoate (C12H19NO3) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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.

As a certified reference material (CRM), Ethyl (2Z)-2-azepan-2-ylidene-3-oxobutanoate 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.
