Chemical Structure

S-Venlafaxine-di-p-toluoyl-L-tartrate Salt CAS 272788-02-0 chemical structure

Description

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.

CATO supplies S-Venlafaxine-di-p-toluoyl-L-tartrate Salt (CAS 272788-02-0), a certified reference material (molecular formula C20H18O8C17H27NO2, MW 663.76 g/mol) for analytical method development and quality control.

S-Venlafaxine-di-p-toluoyl-L-tartrate Salt (C20H18O8C17H27NO2) contains a nitrogen-containing heterocyclic scaffold, an amide group, a hydroxyl group, an ether linkage. The carboxyl group imparts weak acidity; these physicochemical properties determine the optimal preparation and storage of its standard solutions. The aromatic system may exhibit native fluorescence, enabling detection with a fluorescence detector (FLD).

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.
