Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4,4'-(Pyridine-2,5-diyl)dianiline.
4,4'-(Pyridine-2,5-diyl)dianiline (CAS 895156-63-5) is a high-purity analytical reference standard with the molecular formula C17H15N3 and a molecular weight of 261.32 g/mol.
Based on its molecular formula C17H15N3, 4,4'-(Pyridine-2,5-diyl)dianiline contains a nitrogen-containing heterocyclic scaffold, a nitrile group; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 261.32 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 4,4'-(Pyridine-2,5-diyl)dianiline under ISO 17034:2016 accreditation with dual CNAS and ANAB accreditation. Each batch is characterized by orthogonal methods and supplied with a full Certificate of Analysis (COA), ensuring metrological traceability.
