Description

Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including (3S)-3-(9H-fluoren-9-ylmethoxycarbonylamino)-4-(4-fluorophenyl)butanoic acid (3S)-3-(9H-fluoren-9-ylmethoxycarbonylamino)-4-(4-fluorophenyl)butyric acid (3S)-3-[[9H-fluoren-9-ylmethoxy(oxo)methyl]amino]-4-(4-fluorophenyl)butanoic acid 270062-83-4 Fmoc-(S)-3-Amino-4-(4-fluorophenyl)-butyric acid.

CATO supplies (3S)-3-(9H-fluoren-9-ylmethoxycarbonylamino)-4-(4-fluorophenyl)butanoic acid (3S)-3-(9H-fluoren-9-ylmethoxycarbonylamino)-4-(4-fluorophenyl)butyric acid (3S)-3-[[9H-fluoren-9-ylmethoxy(oxo)methyl]amino]-4-(4-fluorophenyl)butanoic acid 270062-83-4 Fmoc-(S)-3-Amino-4-(4-fluorophenyl)-butyric acid (CAS 270062-83-4), a certified reference material (molecular formula C25H22FNO4, MW 419.44 g/mol) for analytical method development and quality control.

(3S)-3-(9H-fluoren-9-ylmethoxycarbonylamino)-4-(4-fluorophenyl)butanoic acid (3S)-3-(9H-fluoren-9-ylmethoxycarbonylamino)-4-(4-fluorophenyl)butyric acid (3S)-3-[[9H-fluoren-9-ylmethoxy(oxo)methyl]amino]-4-(4-fluorophenyl)butanoic acid 270062-83-4 Fmoc-(S)-3-Amino-4-(4-fluorophenyl)-butyric acid (C25H22FNO4) contains a flavonoid core, an amide 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. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

This reference standard is suitable for quantitative analysis on major chromatographic platforms including HPLC, GC, LC-MS/MS, and GC-MS, serving as an external calibration standard or a system suitability test reference material.

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.
