Chemical Structure
Description
CATO supplies 1,2-Bis((2-(pyridin-2-yl)ethyl)thio)ethane (CAS 64691-70-9), a certified reference material (molecular formula C16H20N2S2, MW 304.47 g/mol) for analytical method development and quality control.
1,2-Bis((2-(pyridin-2-yl)ethyl)thio)ethane (C16H20N2S2) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality. Its high carbon-to-hydrogen ratio confers good lipid solubility; 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).
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.
