Chemical Structure
Description
The occurrence of Diethyl 2-acetyl-2-ethylmalonate 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 Diethyl 2-acetyl-2-ethylmalonate (CAS 3378-01-6), a certified reference material (molecular formula C11H18O5, MW 230.26 g/mol) for analytical method development and quality control.
Based on its molecular formula C11H18O5, Diethyl 2-acetyl-2-ethylmalonate contains a carboxylic acid group, a hydroxyl group, an ether linkage; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 230.26 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), Diethyl 2-acetyl-2-ethylmalonate 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.
