Chemical Structure
Description
CATO manufactures (E)-2-methyl-4-(o-tolyldiazenyl)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.
CATO supplies (E)-2-methyl-4-(o-tolyldiazenyl)aniline hydrochloride (CAS 2298-13-7), a certified reference material (molecular formula C14H15N3HCl, MW 261.75 g/mol) for analytical method development and quality control.
The molecular framework of (E)-2-methyl-4-(o-tolyldiazenyl)aniline hydrochloride (C14H15N3HCl) 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.
