Chemical Structure
Description
The occurrence of .alpha.-Ketoglutaric acid diethyl ester 5965-53-7 Diethyl 2-oxoglutarate Diethyl oxalpropionate Ethyl ethoxalylpropionate Glutaric acid, diethyl ester NSC-111179 NSC111179 Pentanedioic acid, diethyl ester is closely related to a carboxylic acid group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies .alpha.-Ketoglutaric acid diethyl ester 5965-53-7 Diethyl 2-oxoglutarate Diethyl oxalpropionate Ethyl ethoxalylpropionate Glutaric acid, diethyl ester NSC-111179 NSC111179 Pentanedioic acid, diethyl ester (CAS 5965-53-7), a certified reference material (molecular formula C9H14O5, MW 202.20 g/mol) for analytical method development and quality control.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, .alpha.-Ketoglutaric acid diethyl ester 5965-53-7 Diethyl 2-oxoglutarate Diethyl oxalpropionate Ethyl ethoxalylpropionate Glutaric acid, diethyl ester NSC-111179 NSC111179 Pentanedioic acid, diethyl ester is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 202.20 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
As a certified reference material (CRM), .alpha.-Ketoglutaric acid diethyl ester 5965-53-7 Diethyl 2-oxoglutarate Diethyl oxalpropionate Ethyl ethoxalylpropionate Glutaric acid, diethyl ester NSC-111179 NSC111179 Pentanedioic acid, diethyl ester 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.
