3-Nitro-4-[(3-pyridinylmethyl)amino]benzoic acid CAS 384855-46-3

Description

The occurrence of 3-Nitro-4-[(3-pyridinylmethyl)amino]benzoic acid is closely related to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

3-Nitro-4-[(3-pyridinylmethyl)amino]benzoic acid (CAS 384855-46-3) is a high-purity analytical reference standard with the molecular formula C13H11N3O4 and a molecular weight of 273.24 g/mol.

The molecular framework of 3-Nitro-4-[(3-pyridinylmethyl)amino]benzoic acid (C13H11N3O4) 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 the protonation state of its nitrogen-containing groups, 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.

As a certified reference material (CRM), 3-Nitro-4-[(3-pyridinylmethyl)amino]benzoic acid 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.
