CATO supplies 7-Chloro-2-phenyl[1,3]oxazolo[5,4-d]pyrimidine (CAS 33360-19-9), a certified reference material (molecular formula C11H6ClN3O, MW 231.64 g/mol) for analytical method development and quality control.
The molecular framework of 7-Chloro-2-phenyl[1,3]oxazolo[5,4-d]pyrimidine (C11H6ClN3O) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, chlorine substitution. 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.
