Description
As a certified reference material (CRM), 3-Methyl-2-(1-tosylpyrrolidin-2-yl)pyridine meets the metrological traceability requirements of ISO/IEC 17025 laboratories. Batch-to-batch consistency is monitored via control charts to guarantee comparable assigned values across lots.
3-Methyl-2-(1-tosylpyrrolidin-2-yl)pyridine (CAS 1352523-51-3) is a high-purity analytical reference standard with the molecular formula C17H20N2O2S and a molecular weight of 316.42 g/mol.
3-Methyl-2-(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.
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
