1-bromo-5-chloro-naphthalene CAS 77332-65-1 chemical structure

Description

CATO manufactures 1-bromo-5-chloro-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.

CATO supplies 1-bromo-5-chloro-naphthalene (CAS 77332-65-1), a certified reference material (molecular formula C10H16BrCl, MW 251.59 g/mol) for analytical method development and quality control.

Based on its molecular formula C10H16BrCl, 1-bromo-5-chloro-naphthalene contains chlorine/bromine substitution; these features give the compound characteristic molecular-ion distribution patterns in mass spectrometry. The molecular weight of 251.59 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. 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.
