1-(4-(3-Cyclopropyl-1,2,4-oxadiazol-5-yl)pyridin-2-yl)-5-methyl-1H-pyrazole-4-carboxylic acid (CAS 1338652-75-7) is a high-purity analytical reference standard with the molecular formula C15H13N5O3 and a molecular weight of 311.30 g/mol.
The molecular framework of 1-(4-(3-Cyclopropyl-1,2,4-oxadiazol-5-yl)pyridin-2-yl)-5-methyl-1H-pyrazole-4-carboxylic acid (C15H13N5O3) is characterized by a nitrogen-containing heterocyclic scaffold, 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. 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.
