Chemical Structure

Diethyl 2-oxoheptanedioate CAS 42212-75-9 chemical structure

Description

CATO supplies Diethyl 2-oxoheptanedioate (CAS 42212-75-9), a certified reference material (molecular formula C11H18O5, MW 230.26 g/mol) for analytical method development and quality control.

The molecular framework of Diethyl 2-oxoheptanedioate (C11H18O5) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the polarity and ionization state of its functional groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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 Diethyl 2-oxoheptanedioate 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.
