4-Aminobenzamidoxime CAS 277319-62-7 chemical structure

Description

CATO supplies 4-Aminobenzamidoxime (CAS 277319-62-7), a certified reference material (molecular formula C7H9N3O, MW 151.17 g/mol) for analytical method development and quality control.

Based on its molecular formula C7H9N3O, 4-Aminobenzamidoxime contains an amide group, a hydroxyl group, an ether linkage, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 151.17 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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), 4-Aminobenzamidoxime 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.
