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 4,4'-(Ethene-1,2-diyl)dianiline dihydrochloride.
4,4'-(Ethene-1,2-diyl)dianiline dihydrochloride (CAS 66635-40-3), molecular formula C14H16N2Cl and molecular weight 247.75 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4,4'-(Ethene-1,2-diyl)dianiline dihydrochloride (C14H16N2Cl) is characterized by a nitrogen-containing heterocyclic scaffold, a nitrile group, chlorine substitution. 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 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.
CATO manufactures 4,4'-(Ethene-1,2-diyl)dianiline dihydrochloride 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.
