Isopropylisothiocyanate (cas: 2253-73-8) belongs to esters. Esters are widespread in nature and are widely used in industry. In nature, fats are in general triesters derived from glycerol and fatty acids. Esters are responsible for the aroma of many fruits, including apples, durians, pears, bananas, pineapples, and strawberries. Because of their lack of hydrogen-bond-donating ability, esters do not self-associate. Consequently, esters are more volatile than carboxylic acids of similar molecular weight.Safety of Isopropylisothiocyanate

Mass Spectra of New Heterocycles: XXII. Electron Impact and Chemical Ionization of 1-Alkyl(cycloalkyl, alkoxyalkyl)-5-[(alkyl, allyl, benzyl)sulfanyl]-1H-pyrrol-2-amines was written by Klyba, L. V.;Nedolya, N. A.;Sanzheeva, E. R.;Tarasova, O. A.. And the article was included in Russian Journal of Organic Chemistry in 2021.Safety of Isopropylisothiocyanate The following contents are mentioned in the article:

Fragmentation of 1-alkyl(cycloalkyl, alkoxyalkyl)-5-[(alkyl, allyl, benzyl)sulfanyl]-1H-pyrrol-2-amines I [R1 = Me, i-Pr, CH2CH2OMe, etc.; R2 = R3 = Me, (CH2)4, (CH2)2O(CH2)2, etc.; R4 = Me, Et, allyl, Bn] under electron impact (70 eV) and chem. ionization (with methane as reactant gas) had been studied for first time. All examined compounds under electron impact generated mol. ion [M]+· (Irel 5-90%) whose primary fragmentation involved mainly cleavage of C-S bond in SR4 substituent with elimination of R4 radical (except for 1-isopropyl- and 1-cycloalkyl-1H-pyrrol-2-amines). The main pathway of decomposition of 1-isopropyl(cycloalkyl)-N,N-dimethyl-5-[(Me, allyl)sulfanyl]-1H-pyrrol-2-amines was cleavage of C-N bond with both elimination of R1 radical from pyrrole nitrogen atom and fragmentation of pyrrole ring through elimination of imine (or aziridine) mol. and formation of odd-electron [M – NR1]+· radical cation. Chem. ionization of title compounds involved protonation, charge exchange, and electrophilic addition processes and elimination of Me (Et) and SMe (SEt) radicals from [M + H]+ ions. This study involved multiple reactions and reactants, such as Isopropylisothiocyanate (cas: 2253-73-8Safety of Isopropylisothiocyanate).
