Abstract
Sodium trifluoromethanesulfinate (NaTFMS) is also known as “Laglois reagent” developed Quantitative 19F-NMR (QNMR) and also employed to determine the amounts of “Laglois reagent” in a mixture containing (NaTFMS) and other inorganic impurities, the amounts of NaTFMS can be measured by high-performance liquid chromatography, but it requires a high-purity standard sample. NMR signal was affecting the response to determined by measuring longitudinal relaxation time (T1) to be 1.2 s is the main parameter ‘‘delay time (d1) between two scans”. Internal reference for the quantitative analysis was used as a trifluoroethanol of sodium trifluoromethane sulphinate by water as solvent. Six experiments with different weights of sodium NaTFMS/TFE and the relative standard deviation (R.S.D.) were repeated and the results are less than 2.0% and also detection limit of 19F-QNMR upto 0.85 mg. 19F-QNMR was calculated and the R.S.D.s of results were less than 2% of each mixture of amount NaTFMS.
