Chemical Structure
Description
Under current pharmacopoeial and regulatory frameworks, quality-control requirements for this class of reference material explicitly involve the control of targets including 4-((4-(4-Chlorophenyl)-1-(4-(4-fluorophenyl)-4-oxobutyl)piperidin-4-yl)oxy)-1-(4-fluorophenyl)butan-1-one.
4-((4-(4-Chlorophenyl)-1-(4-(4-fluorophenyl)-4-oxobutyl)piperidin-4-yl)oxy)-1-(4-fluorophenyl)butan-1-one (CAS CATO-C3D-3484), molecular formula C31H32ClF2NO3 and molecular weight 540.04 g/mol, is a CATO reference standard with documented purity and traceability.
Owing to a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine substitution, 4-((4-(4-Chlorophenyl)-1-(4-(4-fluorophenyl)-4-oxobutyl)piperidin-4-yl)oxy)-1-(4-fluorophenyl)butan-1-one is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 540.04 g/mol — guide the selection of appropriate sample preparation and analytical techniques. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
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.
