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-Difluoro-4-(4-methylpiperazinomethyl) benzophenone (CAS 898763-33-2) is a high-purity analytical reference standard with the molecular formula C19H20F2N2O and a molecular weight of 330.37 g/mol.
Based on its molecular formula C19H20F2N2O, 2,4-Difluoro-4-(4-methylpiperazinomethyl) benzophenone contains a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 330.37 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.
