Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-[2,2,2-Trifluoroethyl-1-O-((4-methylphenyl)sulfonyl)oxime]benzyl Alcohol tert-Butyl(dimethyl)silyl Ether.
4-[2,2,2-Trifluoroethyl-1-O-((4-methylphenyl)sulfonyl)oxime]benzyl Alcohol tert-Butyl(dimethyl)silyl Ether (CAS 87736-80-9), molecular formula C22H28F3NO4SSi and molecular weight 487.61 g/mol, is a CATO reference standard with documented purity and traceability.
Based on its molecular formula C22H28F3NO4SSi, 4-[2,2,2-Trifluoroethyl-1-O-((4-methylphenyl)sulfonyl)oxime]benzyl Alcohol tert-Butyl(dimethyl)silyl Ether contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 487.61 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
