Descrizione generale

p-Toluenesulfonyl isocyanate, a sulfonyl isocyanate derivative, is a highly reactive compound that finds application as a water scavenger. It is used as a component of polyurethane coatings, sealants, adhesives and as an intermediate of several industrially important chemicals.

Applicazioni

p-Toluenesulfonyl isocyanate may be used as a derivatization reagent for the analyses of diethylene glycol and propylene glycol in pharmaceutical products, stereoisomers of 3-hydroxyl-7-methyl-norethynodrel in biological samples, and pyrrolizidine alkaloids in herbal tea formulations by high performance liquid chromatography (HPLC) based techniques.

The Fourier transform infrared (FTIR) and FT Raman spectra of p-toluenesulfonyl isocyanate (p-tosyl isocyanate) have been measured. The molecular geometry, vibrational frequencies, infrared intensities, Raman activities and atomic charges have been calculated by using ab initio HF and density functional

In this paper, p-toluenesulfonyl isocyanate has been reported as a novel derivatization reagent with strong nuclephilic reactivity for the hydroxyl compounds. The derivatization for the two pharmacologically active 3-hydroxyl metabolites, 3alpha-hydroxyl-7-methyl-norethynodrel and 3beta-hydroxyl-7-methyl-norethynodrel by p-toluenesulfonyl isocyanate can be accomplished in
