Chemical Structure

5-(4-Aminophenyl)pyridin-2-amine CAS 96721-87-8 chemical structure

Description

As a certified reference material (CRM), 5-(4-Aminophenyl)pyridin-2-amine 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.

5-(4-Aminophenyl)pyridin-2-amine (CAS 96721-87-8), molecular formula C11H11N3 and molecular weight 185.23 g/mol, is a CATO reference standard with documented purity and traceability.

Owing to a nitrogen-containing heterocyclic scaffold, a nitrile group, 5-(4-Aminophenyl)pyridin-2-amine is typically pale yellow to yellow low-melting solid. Its solid-state physicochemical attributes — including a molecular weight of 185.23 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
