Chemical Structure

N-(2,4-diaminophenyl)benzamide CAS 56120-01-5 chemical structure

Description

N-(2,4-diaminophenyl)benzamide (CAS 56120-01-5) is a high-purity analytical reference standard with the molecular formula C13H13N3O and a molecular weight of 227.26 g/mol.

The molecular framework of N-(2,4-diaminophenyl)benzamide (C13H13N3O) is characterized by a nitrogen-containing heterocyclic scaffold, 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.

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-(2,4-diaminophenyl)benzamide 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.
