Description

The occurrence of (3R)-3-(9H-fluoren-9-ylmethoxycarbonylamino)-4-[4-(trifluoromethyl)phenyl]butanoic acid (3R)-3-(9H-fluoren-9-ylmethoxycarbonylamino)-4-[4-(trifluoromethyl)phenyl]butyric acid (3R)-3-[[9H-fluoren-9-ylmethoxy(oxo)methyl]amino]-4-[4-(trifluoromethyl)phenyl]butanoic acid 269726-78-5 Fmoc-(R)-3-Amino-4-(4-trifluoromethylphenyl)-butyric acid is closely related to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution in its molecular formula, which determines its behaviour during synthesis, purification, or degradation.

(3R)-3-(9H-fluoren-9-ylmethoxycarbonylamino)-4-[4-(trifluoromethyl)phenyl]butanoic acid (3R)-3-(9H-fluoren-9-ylmethoxycarbonylamino)-4-[4-(trifluoromethyl)phenyl]butyric acid (3R)-3-[[9H-fluoren-9-ylmethoxy(oxo)methyl]amino]-4-[4-(trifluoromethyl)phenyl]butanoic acid 269726-78-5 Fmoc-(R)-3-Amino-4-(4-trifluoromethylphenyl)-butyric acid (CAS 269726-78-5) is a high-purity analytical reference standard with the molecular formula C26H22F3NO4 and a molecular weight of 469.45 g/mol.

The molecular framework of (3R)-3-(9H-fluoren-9-ylmethoxycarbonylamino)-4-[4-(trifluoromethyl)phenyl]butanoic acid (3R)-3-(9H-fluoren-9-ylmethoxycarbonylamino)-4-[4-(trifluoromethyl)phenyl]butyric acid (3R)-3-[[9H-fluoren-9-ylmethoxy(oxo)methyl]amino]-4-[4-(trifluoromethyl)phenyl]butanoic acid 269726-78-5 Fmoc-(R)-3-Amino-4-(4-trifluoromethylphenyl)-butyric acid (C26H22F3NO4) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by the protonation state of its nitrogen-containing groups, which provides a practical basis for HPLC-UV/DAD or LC-MS method development. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.

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.
