Description
CATO manufactures (E)-4-(phenyldiazenyl)aniline hydrochloride 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.
(E)-4-(phenyldiazenyl)aniline hydrochloride (CAS 287481-35-0), molecular formula C12H11N3HCl and molecular weight 233.70 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (E)-4-(phenyldiazenyl)aniline hydrochloride (C12H11N3HCl) 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. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
