Chemical Structure
Description
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.
4-(4-Chlorophenyl)-1-[3-[2-(4-fluorophenyl)-1,3-dioxolan-2-yl]propyl]-4-piperidinol (CAS 56660-99-2), molecular formula C23H27ClFNO3 and molecular weight 419.92 g/mol, is a CATO reference standard with documented purity and traceability.
The molecular framework of 4-(4-Chlorophenyl)-1-[3-[2-(4-fluorophenyl)-1,3-dioxolan-2-yl]propyl]-4-piperidinol (C23H27ClFNO3) is characterized by a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine/chlorine 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 aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
