Chemical Structure
Description
The molecular framework of 4-(Benzo[d]thiazol-2(3H)-ylidene)-2-phenyloxazol-5(4H)-one (C16H10N2O2S) is characterized by a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
CATO supplies 4-(Benzo[d]thiazol-2(3H)-ylidene)-2-phenyloxazol-5(4H)-one (CAS 919201-81-3), a certified reference material (molecular formula C16H10N2O2S, MW 294.33 g/mol) for analytical method development and quality control.
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.
