Chemical Structure
Description
Owing to a flavonoid core, an amide group, a hydroxyl group, an ether linkage, chlorine substitution, (3S)-4-(2-chlorophenyl)-3-(9H-fluoren-9-ylmethoxycarbonylamino)butanoic acid (3S)-4-(2-chlorophenyl)-3-(9H-fluoren-9-ylmethoxycarbonylamino)butyric acid (3S)-4-(2-chlorophenyl)-3-[[9H-fluoren-9-ylmethoxy(oxo)methyl]amino]butanoic acid 270596-37-7 Fmoc-(S)-3-Amino-4-(2-chlorophenyl)-butyric acid is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 435.90 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.
(3S)-4-(2-chlorophenyl)-3-(9H-fluoren-9-ylmethoxycarbonylamino)butanoic acid (3S)-4-(2-chlorophenyl)-3-(9H-fluoren-9-ylmethoxycarbonylamino)butyric acid (3S)-4-(2-chlorophenyl)-3-[[9H-fluoren-9-ylmethoxy(oxo)methyl]amino]butanoic acid 270596-37-7 Fmoc-(S)-3-Amino-4-(2-chlorophenyl)-butyric acid (CAS 270596-37-7) is a high-purity analytical reference standard with the molecular formula C25H22ClNO4 and a molecular weight of 435.90 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.
