N-Phenylhydroxylamine oxalate CAS 84447-15-4

Description

The occurrence of N-Phenylhydroxylamine oxalate is closely related to an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

N-Phenylhydroxylamine oxalate (CAS 84447-15-4), molecular formula C6H7NOC2H2O4 and molecular weight 199.16 g/mol, is a CATO reference standard with documented purity and traceability.

The molecular framework of N-Phenylhydroxylamine oxalate (C6H7NOC2H2O4) is characterized by an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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), N-Phenylhydroxylamine oxalate 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.
