CATO supplies (2S)-2-(9H-fluoren-9-ylmethoxycarbonylamino)-3-[4-(trifluoromethyl)phenyl]propanoic acid (2S)-2-(9H-fluoren-9-ylmethoxycarbonylamino)-3-[4-(trifluoromethyl)phenyl]propionic acid (2S)-2-[[9H-fluoren-9-ylmethoxy(oxo)methyl]amino]-3-[4-(trifluoromethyl)phenyl]propanoic acid 247113-86-6 Fmoc-L-4-Trifluoromethylphe (CAS 247113-86-6), a certified reference material (molecular formula C25H20F3NO4, MW 455.43 g/mol) for analytical method development and quality control.
Based on its molecular formula C25H20F3NO4, (2S)-2-(9H-fluoren-9-ylmethoxycarbonylamino)-3-[4-(trifluoromethyl)phenyl]propanoic acid (2S)-2-(9H-fluoren-9-ylmethoxycarbonylamino)-3-[4-(trifluoromethyl)phenyl]propionic acid (2S)-2-[[9H-fluoren-9-ylmethoxy(oxo)methyl]amino]-3-[4-(trifluoromethyl)phenyl]propanoic acid 247113-86-6 Fmoc-L-4-Trifluoromethylphe contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution; these features give the compound characteristic absorption bands in UV spectroscopy. The molecular weight of 455.43 g/mol is directly relevant to the identification of the molecular ion in mass spectrometry. Nitrogen-containing functional groups confer excellent ionization efficiency in positive-ion electrospray (ESI) mode, making the compound well suited to LC-MS/MS analysis.
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.
