Uses

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

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.
