Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (S)-4-fluoro-4-methyl-2-((S)-2,2,2-trifluoro-1-(4-(methylsulfonyl)biphenyl-4-yl)ethylamino)pentanoic acid.
(S)-4-fluoro-4-methyl-2-((S)-2,2,2-trifluoro-1-(4-(methylsulfonyl)biphenyl-4-yl)ethylamino)pentanoic acid (CAS 875272-89-2) is a high-purity analytical reference standard with the molecular formula C21H23F4NO4S and a molecular weight of 461.47 g/mol.
Based on its molecular formula C21H23F4NO4S, (S)-4-fluoro-4-methyl-2-((S)-2,2,2-trifluoro-1-(4-(methylsulfonyl)biphenyl-4-yl)ethylamino)pentanoic acid 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 461.47 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.
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.
