Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
Cis 1-Benzyl-4-(4-fluorophenyl)-6-oxopiperidine-3-carboxylic Acid Methyl Ester (CAS 612095-73-5) is a high-purity analytical reference standard with the molecular formula C20H20FNO3 and a molecular weight of 341.38 g/mol.
The molecular framework of Cis 1-Benzyl-4-(4-fluorophenyl)-6-oxopiperidine-3-carboxylic Acid Methyl Ester (C20H20FNO3) is characterized by 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).
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.
