CATO supplies 6R4XQV6J08 2944-68-5 Ferric tartrate Diiron tritartrate EINECS 220-953-8 UNII-6R4XQV6J08 (CAS 2944-68-5), a certified reference material (molecular formula C12H12Fe2O18, MW 555.90 g/mol) for analytical method development and quality control.
6R4XQV6J08 2944-68-5 Ferric tartrate Diiron tritartrate EINECS 220-953-8 UNII-6R4XQV6J08 (C12H12Fe2O18) contains a carbohydrate-derived structure. It is notably hygroscopic, 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.
