Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 384.59 g/mol gives Diethyl 2-hexadecylmalonate distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
CATO supplies Diethyl 2-hexadecylmalonate (CAS 41433-81-2), a certified reference material (molecular formula C23H44O4, MW 384.59 g/mol) for analytical method development and quality control.
Owing to a carboxylic acid group, a hydroxyl group, an ether linkage, Diethyl 2-hexadecylmalonate is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 384.59 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
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-hexadecylmalonate 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.
