Chemical Structure
Description
The molecular framework of 5,5'-(Naphthalene-2,6-diyl)bis(benzene-1,3-diamine) (C22H20N4) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
5,5'-(Naphthalene-2,6-diyl)bis(benzene-1,3-diamine) (CAS 1569868-40-1) is a high-purity analytical reference standard with the molecular formula C22H20N4 and a molecular weight of 340.42 g/mol.
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 5,5'-(Naphthalene-2,6-diyl)bis(benzene-1,3-diamine) 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.
