Manufacturer Good Price P-TOLUENESULFONYLISOCYANATE (PTSI) CAS 4083-64-1

short description:

P-TOLUENESULFONYLISOCYANATE (PTSI) is a single functional isocyanate. P-TOLUENESULFONYLISOCYANATE (PTSI) has high activity and can react with conventional diisocyanates, such as TDI and HDI, with water in polyols and solvents. The resulting carbamate does not increase the viscosity of the system. The disadvantage is that the toxicity of oxazolidine and other dehydrants is large; P-TOLUENESULFONYLISOCYANATE (PTSI) reacts with water to produce carbon dioxide and toluenesulfamide, so P-TOLUENESULFONYLISOCYANATE (PTSI) cannot be used directly in paint formulations and is generally used for pre-dehydration. To remove 1g of water in the solvent, about 12g of PTSI is theoretically required, but the actual amount should be higher than this.

Applications of PTSI

1.p-Toluenesulfonyl isocyanate is a reagent used to prepare acetylated syn-1,2-diols,1 oxazolidin-2-ones,2 2,3-diamino acids,3 and N-tosylcarbonamides.4

2.It is a reagent used to prepare acetylated syn-1,2-diols,oxazolidin-2-ones, 2,3-diamino acids, and N-tosylcarbonamides. -Toluenesulfonyl isocyanate has been used as derivatization reagent in determination of 3-α-hydroxy tibolone in human plasma by LC-MS/MS. It is also employed in the derivatization reagent in simultaneous quantitative analysis of diethylene glycol and propylene glycol in pharmaceutical products by HPLC and as reagent in the preparation of acetylated syn-1,2-diols, oxazolidin-2-ones, 2,3-diamino acids and N-tosylcarbonamides.
