Chemical Structure
Description
4-Methylnaphthalen-1-amine hydrochloride (CAS 51671-01-3), molecular formula C11H11NHCl and molecular weight 193.67 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-Methylnaphthalen-1-amine hydrochloride (C11H11NHCl) 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-Methylnaphthalen-1-amine 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.
