Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
CATO supplies Fmoc-4-(2-fluorophenyl)-L-phenylalanine (CAS 352525-27-0), a certified reference material (molecular formula C30H24FNO4, MW 481.51 g/mol) for analytical method development and quality control.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, Fmoc-4-(2-fluorophenyl)-L-phenylalanine is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 481.51 g/mol — guide the selection of appropriate sample preparation and analytical techniques. 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.
