Chemical Structure
Description
1,3-Diethyl 2-{[3-(4-ethylphenoxy)phenyl]methylidene}propanedioate (CAS 866154-79-2) is a high-purity analytical reference standard with the molecular formula C22H24O5 and a molecular weight of 368.42 g/mol.
1,3-Diethyl 2-{[3-(4-ethylphenoxy)phenyl]methylidene}propanedioate (C22H24O5) contains a flavonoid core, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. 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), 1,3-Diethyl 2-{[3-(4-ethylphenoxy)phenyl]methylidene}propanedioate 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.
