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-(4-Bromophenyl)-2'-iodoacetophenone (CAS 898783-94-3), molecular formula C14H10BrIO and molecular weight 401.04 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C14H10BrIO, 2-(4-Bromophenyl)-2'-iodoacetophenone contains a hydroxyl group, an ether linkage, bromine/iodine substitution, a polycyclic aromatic system; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 401.04 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Halogen substitution (F/Cl/Br/I) produces a distinctive isotope pattern in mass spectrometry, a valuable aid for qualitative confirmation.
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.
