(3S)-4-(3-cyanophenyl)-3-(9H-fluoren-9-ylmethoxycarbonylamino)butanoic acid (3S)-4-(3-cyanophenyl)-3-(9H-fluoren-9-ylmethoxycarbonylamino)butyric acid (3S)-4-(3-cyanophenyl)-3-[[9H-fluoren-9-ylmethoxy(oxo)methyl]amino]butanoic acid 270065-87-7 Fmoc-(S)-3-Amino-4-(3-cyanophenyl)-butyric acid (CAS 270065-87-7), molecular formula C26H22N2O4 and molecular weight 426.46 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of (3S)-4-(3-cyanophenyl)-3-(9H-fluoren-9-ylmethoxycarbonylamino)butanoic acid (3S)-4-(3-cyanophenyl)-3-(9H-fluoren-9-ylmethoxycarbonylamino)butyric acid (3S)-4-(3-cyanophenyl)-3-[[9H-fluoren-9-ylmethoxy(oxo)methyl]amino]butanoic acid 270065-87-7 Fmoc-(S)-3-Amino-4-(3-cyanophenyl)-butyric acid (C26H22N2O4) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage. 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.
As a certified reference material (CRM), (3S)-4-(3-cyanophenyl)-3-(9H-fluoren-9-ylmethoxycarbonylamino)butanoic acid (3S)-4-(3-cyanophenyl)-3-(9H-fluoren-9-ylmethoxycarbonylamino)butyric acid (3S)-4-(3-cyanophenyl)-3-[[9H-fluoren-9-ylmethoxy(oxo)methyl]amino]butanoic acid 270065-87-7 Fmoc-(S)-3-Amino-4-(3-cyanophenyl)-butyric acid meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
