Chemical Structure
Description
CATO supplies 3-(3,5-Dimethylbenzenesulfonyl)-4,6-dimethyl-2-(2-methylpropoxy)pyridine (CAS 338412-22-9), a certified reference material (molecular formula C19H25NO3S, MW 347.47 g/mol) for analytical method development and quality control.
3-(3,5-Dimethylbenzenesulfonyl)-4,6-dimethyl-2-(2-methylpropoxy)pyridine (C19H25NO3S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. Its high carbon-to-hydrogen ratio confers good lipid solubility, 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).
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.
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.
