Chemical Structure
Description
The occurrence of 4-bromo-5-chloro-naphthalen-2-ol is closely related to a hydroxyl group, an ether linkage, chlorine/bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
CATO supplies 4-bromo-5-chloro-naphthalen-2-ol (CAS 2454397-73-8), a certified reference material (molecular formula C10H16BrClO, MW 267.59 g/mol) for analytical method development and quality control.
Owing to a hydroxyl group, an ether linkage, chlorine/bromine substitution, 4-bromo-5-chloro-naphthalen-2-ol is typically white to off-white crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 267.59 g/mol — guide the selection of appropriate sample preparation and analytical techniques. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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-bromo-5-chloro-naphthalen-2-ol 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.
