CATO supplies 3-(pyridin-3-yl)-4,5-dihydro-1,2-oxazol-5-one (CAS 101084-94-0), a certified reference material (molecular formula C8H6N2O2, MW 162.15 g/mol) for analytical method development and quality control.
The molecular framework of 3-(pyridin-3-yl)-4,5-dihydro-1,2-oxazol-5-one (C8H6N2O2) 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.
