Chemical Structure
Description
The occurrence of Diethyl 2-allyl-2-(3-phenylprop-2-yn-1-yl)malonate is closely related to a flavonoid core, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
Diethyl 2-allyl-2-(3-phenylprop-2-yn-1-yl)malonate (CAS 143633-91-4), molecular formula C19H22O4 and molecular weight 314.38 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a flavonoid core, a hydroxyl group, an ether linkage, Diethyl 2-allyl-2-(3-phenylprop-2-yn-1-yl)malonate is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 314.38 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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-allyl-2-(3-phenylprop-2-yn-1-yl)malonate 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.
