Chemical Structure
Description
The molecular framework of 4-Chloro-3-(oxazol-5-yl)aniline (C9H7ClN2O) 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 the protonation state of its nitrogen-containing groups, 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.
4-Chloro-3-(oxazol-5-yl)aniline (CAS 521983-07-3), molecular formula C9H7ClN2O and molecular weight 194.62 g/mol, is a CATO reference standard with documented purity and traceability.
