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)-(1-Acetylpyrrolidin-2-yl)methyl 4-methylbenzenesulfonate (CAS 1353994-74-7), a certified reference material (molecular formula C14H19NO4S, MW 297.37 g/mol) for analytical method development and quality control.
(S)-(1-Acetylpyrrolidin-2-yl)methyl 4-methylbenzenesulfonate (C14H19NO4S) contains a nitrogen-containing heterocyclic scaffold, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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.
