Chemical Structure
Description
The occurrence of 3-bromonaphthalene-2-carbaldehyde is closely related to a hydroxyl group, an ether linkage, bromine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.
3-bromonaphthalene-2-carbaldehyde (CAS 89005-11-8) is a high-purity analytical reference standard with the molecular formula C11H17BrO and a molecular weight of 245.16 g/mol.
The molecular framework of 3-bromonaphthalene-2-carbaldehyde (C11H17BrO) is characterized by a hydroxyl group, an ether linkage, bromine 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. 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 3-bromonaphthalene-2-carbaldehyde 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.
