Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Diethyl 2-allyl-2-(prop-2-ynyl)malonate (CAS 101268-55-7), molecular formula C13H18O4 and molecular weight 238.28 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of Diethyl 2-allyl-2-(prop-2-ynyl)malonate (C13H18O4) is characterized by a carboxylic acid group, a hydroxyl group, an ether linkage, an aromatic ring system. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
As a certified reference material (CRM), Diethyl 2-allyl-2-(prop-2-ynyl)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.
