Chemical Structure
Description
Compared with other compounds in its class, the molecular weight of 261.16 g/mol gives 3-bromonaphthalene-2-carboxylic acid distinctive chromatographic separation conditions and mass-spectrometry parameter settings.
3-bromonaphthalene-2-carboxylic acid (CAS 20717-80-0) is a high-purity analytical reference standard with the molecular formula C11H17BrO2 and a molecular weight of 261.16 g/mol.
The molecular framework of 3-bromonaphthalene-2-carboxylic acid (C11H17BrO2) is characterized by a carboxylic acid group, 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. The high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO manufactures 3-bromonaphthalene-2-carboxylic acid 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.
