Chemical Structure
Description
(R)-N-(4-Fluorophenyl)-N-[(4-methylphenyl)-sulfonyl]alanine 1562441-57-9 (C16H16FNO4S) contains a flavonoid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage, fluorine substitution. Halogen substitution raises its density and boiling point, the carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
(R)-N-(4-Fluorophenyl)-N-[(4-methylphenyl)-sulfonyl]alanine 1562441-57-9 (CAS 1562441-57-9) is a high-purity analytical reference standard with the molecular formula C16H16FNO4S and a molecular weight of 337.37 g/mol.
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.
