Description
CATO manufactures 5-Bromo-1-(chloromethyl)naphthalene 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.
5-Bromo-1-(chloromethyl)naphthalene (CAS 20366-58-9) is a high-purity analytical reference standard with the molecular formula C11H8BrCl and a molecular weight of 255.54 g/mol.
The molecular framework of 5-Bromo-1-(chloromethyl)naphthalene (C11H8BrCl) is characterized by chlorine/bromine substitution, an aromatic ring system. 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.
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.
