Chemical Structure

1-BROMO-7-CHLORO-2-NAPHTHALDEHYDE CAS 925442-70-2 chemical structure

Description

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.

1-BROMO-7-CHLORO-2-NAPHTHALDEHYDE (CAS 925442-70-2), molecular formula C11H6BrClO and molecular weight 269.52 g/mol, is a CATO reference standard with documented purity and traceability.

1-BROMO-7-CHLORO-2-NAPHTHALDEHYDE (C11H6BrClO) contains a hydroxyl group, an ether linkage, chlorine/bromine substitution, an aromatic ring system. Halogen substitution raises its density and boiling point, its high carbon-to-hydrogen ratio confers good lipid solubility; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.

CATO manufactures 1-BROMO-7-CHLORO-2-NAPHTHALDEHYDE 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.
