Abstract
|
|
|
|
A rapid and accurate NMR procedure for the analysis of a mixture of sulfametrol, sulfalene and sulfameter in CDCl3 and dimethylsulfoxide-d6 was developed. Thioacetamide was used as an internal standard. The signals chosen for the analysis were a singlet of 4.03ppm due to the methoxyl group of sulfametrol, a singlet of 3.98ppm due to the methoxyl group of sulfalene and a singlet of 3.83ppm due to the methoxyl group of sulfameter. The quantification of the characteristic peak was done by the integration method and the peak height method. The variation coefficient of sulfametrol, sulfalene and sulfameter were 1.7(n=6), 1.7(n=6) and 1.4%(n=6), respectively in the peak height method and 8.9(n=6), 9.4(n=6) and 7.0(n=6), respectively in the integration method.
