Chemical Structure
Description
CATO supplies 5-Phenyl-2-propyl-7H-pyrazolo[5,1-b][1,3]oxazin-7-one (CAS 919533-18-9), a certified reference material (molecular formula C15H14N2O2, MW 254.28 g/mol) for analytical method development and quality control.
The molecular framework of 5-Phenyl-2-propyl-7H-pyrazolo[5,1-b][1,3]oxazin-7-one (C15H14N2O2) 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 its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 5-Phenyl-2-propyl-7H-pyrazolo[5,1-b][1,3]oxazin-7-one under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
