Isopropylisothiocyanate (cas: 2253-73-8) belongs to esters. Volatile esters with characteristic odours are used in synthetic flavours, perfumes, and cosmetics. Certain volatile esters are used as solvents for lacquers, paints, and varnishes. Cyclic esters are called lactones, regardless of whether they are derived from an organic or inorganic acid. One example of an organic lactone is γ-valerolactone.COA of Formula: C4H7NS

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.COA of Formula: C4H7NS 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: 2253-73-8COA of Formula: C4H7NS).
