Chemical Structure
Description
2-Methyl-5-(1-tosylpyrrolidin-2-yl)pyridine (C17H20N2O2S) contains a steroid core, an amide group, a sulfone group, a hydroxyl group, an ether linkage. It is notably hygroscopic, 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 high carbon-to-hydrogen ratio imparts good lipophilicity, allowing liquid-liquid extraction with non-polar solvents such as n-hexane or ethyl acetate.
2-Methyl-5-(1-tosylpyrrolidin-2-yl)pyridine (CAS 1352502-87-4), molecular formula C17H20N2O2S and molecular weight 316.42 g/mol, is a CATO reference standard with documented purity and traceability.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
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.
