2-N-phenylpyridine-2,4-diamine CAS 25194-51-8 chemical structure

Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 2-N-phenylpyridine-2,4-diamine.

2-N-phenylpyridine-2,4-diamine (CAS 25194-51-8) is a high-purity analytical reference standard with the molecular formula C11H11N3 and a molecular weight of 185.23 g/mol.

2-N-phenylpyridine-2,4-diamine (C11H11N3) contains a nitrogen-containing heterocyclic scaffold, a nitrile group. Its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.

As a certified reference material (CRM), 2-N-phenylpyridine-2,4-diamine 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.
