Description
Recommended for analytical method development and validation; each product is supplied with a full Certificate of Analysis (COA) ensuring ISO 17034 metrological traceability.
2,2'-(Ethane-1,2-diyl)bis(quinolin-8-ol) (CAS 249614-38-8), molecular formula C20H16N2O2 and molecular weight 316.35 g/mol, is a CATO reference standard with documented purity and traceability.
2,2'-(Ethane-1,2-diyl)bis(quinolin-8-ol) (C20H16N2O2) contains a steroid core, an amide 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 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.
