3,4-bis(4-chlorophenyl)-1,2-oxazol-5-amine CAS 1096934-06-3

Description

3,4-bis(4-chlorophenyl)-1,2-oxazol-5-amine (CAS 1096934-06-3), molecular formula C15H10Cl2N2O and molecular weight 305.16 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of 3,4-bis(4-chlorophenyl)-1,2-oxazol-5-amine (C15H10Cl2N2O) 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.

As a certified reference material (CRM), 3,4-bis(4-chlorophenyl)-1,2-oxazol-5-amine meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
