Chemical Structure
Description
As a certified reference material (CRM), 3-(Naphtho[1,2-d]oxazol-2-yl)aniline 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.
3-(Naphtho[1,2-d]oxazol-2-yl)aniline (CAS 874999-97-0), molecular formula C17H12N2O and molecular weight 260.29 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 3-(Naphtho[1,2-d]oxazol-2-yl)aniline (C17H12N2O) is characterized by a steroid core, 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).
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.
