4-Aminonicotinic acid CAS 7418-65-7

Description

Compared with other compounds in its class, the molecular weight of 138.12 g/mol gives 4-Aminonicotinic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.

CATO supplies 4-Aminonicotinic acid (CAS 7418-65-7), a certified reference material (molecular formula C6H6N2O2, MW 138.12 g/mol) for analytical method development and quality control.

Structurally, 4-Aminonicotinic acid (C6H6N2O2) contains an amino-acid-derived structure, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 5.0, corresponding to approximately 5 ring(s) or double-bond equivalent(s). With a molecular weight of 138.12 g/mol, it falls into the low-molecular-weight range. 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), 4-Aminonicotinic 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.
