Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
1,3-Phenylenebis(ethane-2,1-diyl) dicarbamimidothioate dihydrobromide (CAS 200716-66-1), molecular formula C12H18N4S2HBr and molecular weight 363.34 g/mol, is a CATO reference standard with documented purity and traceability.
1,3-Phenylenebis(ethane-2,1-diyl) dicarbamimidothioate dihydrobromide (C12H18N4S2HBr) contains a nitrogen-containing heterocyclic scaffold, a nitrile group, sulfur-containing functionality, bromine substitution. Halogen substitution raises its density and boiling point, 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).
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.
