4-Fluoro-α-(2-methyl-1-oxopropyl)-γ-oxo-N,β-diphenyl-d5-benzenebutanamide (CAS 222412-75-1), molecular formula C26H19D5FNO3 and molecular weight 422.50 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-Fluoro-α-(2-methyl-1-oxopropyl)-γ-oxo-N,β-diphenyl-d5-benzenebutanamide (C26H19D5FNO3) is characterized by deuterium isotope labeling, a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution. In reversed-phase chromatography, its retention is governed primarily by its high hydrophobicity (logP), which provides a practical basis for HPLC-UV/DAD or LC-MS method development. 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).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
