Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-(3-Isopropyl-1,2,4-oxadiazol-5-yl)-6,7-dihydropyrazolo[1,5-a]pyridin-4(5H)-one.
2-(3-Isopropyl-1,2,4-oxadiazol-5-yl)-6,7-dihydropyrazolo[1,5-a]pyridin-4(5H)-one (CAS 1708251-38-0) is a high-purity analytical reference standard with the molecular formula C12H14N4O2 and a molecular weight of 246.27 g/mol.
The molecular framework of 2-(3-Isopropyl-1,2,4-oxadiazol-5-yl)-6,7-dihydropyrazolo[1,5-a]pyridin-4(5H)-one (C12H14N4O2) is characterized by an amino-acid-derived structure, 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.
