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.
CATO supplies Trans 1-Benzyl-4-(4-fluorophenyl)-6-oxopiperidine-3-carboxylic Acid Methyl Ester (CAS 612095-72-4), a certified reference material (molecular formula C20H20FNO3, MW 341.38 g/mol) for analytical method development and quality control.
Owing to a steroid core, an amide group, a hydroxyl group, an ether linkage, fluorine substitution, Trans 1-Benzyl-4-(4-fluorophenyl)-6-oxopiperidine-3-carboxylic Acid Methyl Ester is typically pale yellow to yellow crystalline powder. Its solid-state physicochemical attributes — including a molecular weight of 341.38 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.
