Description
As a certified reference material (CRM), Ethyl 2-methyl-2-(4-(5-(pyridin-3-yl)-1,2,4-oxadiazol-3-yl)phenoxy)propanoate 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.
Ethyl 2-methyl-2-(4-(5-(pyridin-3-yl)-1,2,4-oxadiazol-3-yl)phenoxy)propanoate (CAS 40915-84-2) is a high-purity analytical reference standard with the molecular formula C19H19N3O4 and a molecular weight of 353.37 g/mol.
The molecular framework of Ethyl 2-methyl-2-(4-(5-(pyridin-3-yl)-1,2,4-oxadiazol-3-yl)phenoxy)propanoate (C19H19N3O4) is characterized by a flavonoid core, an amide group, a hydroxyl group, an ether linkage. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
