Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2-Bromo-1-(naphthalen-1-yl)ethanone (CAS 13686-51-6), molecular formula C12H9BrO and molecular weight 249.10 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C12H9BrO, 2-Bromo-1-(naphthalen-1-yl)ethanone contains a hydroxyl group, an ether linkage, bromine substitution, an aromatic ring system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 249.10 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.
CATO manufactures 2-Bromo-1-(naphthalen-1-yl)ethanone 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.
