Chemical Structure
Description
Based on its molecular formula C11H16BrClO2, 8-bromo-3-chloro-naphthalene-1-carboxylic acid contains a carboxylic acid group, a hydroxyl group, an ether linkage, chlorine/bromine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 295.60 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.
8-bromo-3-chloro-naphthalene-1-carboxylic acid (CAS 2387596-42-9), molecular formula C11H16BrClO2 and molecular weight 295.60 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
As a certified reference material (CRM), 8-bromo-3-chloro-naphthalene-1-carboxylic acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
