Description

CAS: 4083-64-1 | C8H7NO3S | 197.21 g/mol

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.

This Thermo Scientific Chemicals brand product was originally part of the Alfa Aesar product portfolio. Some documentation and label information may refer to the legacy brand. The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.
