Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
8-(2-Bromophenyl)-8-oxooctanoic acid (CAS 898765-30-5), molecular formula C14H17BrO3 and molecular weight 313.19 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C14H17BrO3, 8-(2-Bromophenyl)-8-oxooctanoic acid contains a carboxylic acid group, 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 313.19 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
The assigned purity is verified by mass-balance and quantitative NMR (qNMR) approaches, with the expanded uncertainty reported at a 95% confidence level (k=2). Batch homogeneity and stability are independently assessed for every lot.
