(2R)-3-(4-cyanophenyl)-2-(9H-fluoren-9-ylmethoxycarbonylamino)propanoic acid (2R)-3-(4-cyanophenyl)-2-(9H-fluoren-9-ylmethoxycarbonylamino)propionic acid (2R)-3-(4-cyanophenyl)-2-[[9H-fluoren-9-ylmethoxy(oxo)methyl]amino]propanoic acid 205526-34-7 Fmoc-D-4-Cyanophe (CAS 205526-34-7), molecular formula C25H38N2O4 and molecular weight 430.58 g/mol, is a CATO reference standard with documented purity and traceability.
Structurally, (2R)-3-(4-cyanophenyl)-2-(9H-fluoren-9-ylmethoxycarbonylamino)propanoic acid (2R)-3-(4-cyanophenyl)-2-(9H-fluoren-9-ylmethoxycarbonylamino)propionic acid (2R)-3-(4-cyanophenyl)-2-[[9H-fluoren-9-ylmethoxy(oxo)methyl]amino]propanoic acid 205526-34-7 Fmoc-D-4-Cyanophe (C25H38N2O4) contains a flavonoid core, an amide group, a hydroxyl group, an ether linkage. The molecule exhibits a degree of unsaturation (DBE) of 8.0, corresponding to approximately 8 ring(s) or double-bond equivalent(s). With a molecular weight of 430.58 g/mol, it falls into the moderately-high-molecular-weight range. The presence of an aromatic ring or conjugated system gives the compound characteristic absorption bands in the UV-Vis region, making it well suited to UV or diode-array detection (DAD).
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.
