Other nitrogen-containing compounds such as 2-phenylacetonitrile (0.1%) and (2-nitroethyl)-benzene (0.15%) have been identified by Maurer. With its low treshold of 2 ng/l water (0.002ppb), 2-isopropyl-3-methoxypyrazine (1 ppm) is also important and imparts neroli with an interesting green note." \\ | "The combination of these two sesquiterpene alcohols [(+)-(E)-nerolidol 3% and (E,E)-farnesol 1%], a considerable amount of [[http://www.thegoodscentscompany.com/data/rw1004392.html|methyl N-methylanthranilate]] (0.1%), which resembles the odor of concord grapes, and 1H-indole (0.1%), which, on high dilution posesses a distinct exotic jasmine note, differentiate neroli from petitgrain oil.

| "In addition to linalool, the other important alcohols are geraniol (2.5%), nerol (0.4%), α-terpineol (5.6%), (+)-(R,E)-nerolidol (0.05%) and the intensely woody smelling (+)-spathulenol and (+)-isospathulenol (0.03%)... Although more than 100 carbonyl compounds found in petitgrain oils account for only 0.37%, their importance is unquestioned, among them high-impact compounds as β-ionone (5 ppm) and β-damascenone (2 ppm) that occur in concentrations way above their odor tresholds (0.009 and 0.007 ppb, resp.)...\\ | "In addition to linalool, the other important alcohols are geraniol (2.5%), nerol (0.4%), α-terpineol (5.6%), (+)-(R,E)-nerolidol (0.05%) and the intensely woody smelling (+)-spathulenol and (+)-isospathulenol (0.03%)...

| Another important constituent is 2-isopropyl-3-methoxypyrazine with its typical galbanum-like, green note that can be found together with ten other substituted pyrazines. The concentration of [it] in petitgrain oil is 1 ppm, which exceeds its odor treshold by a million times." \\ | Another important constituent is [[http://www.thegoodscentscompany.com/data/rw1107761.html|2-isopropyl-3-methoxypyrazine]] with its typical galbanum-like, green note that can be found together with ten other substituted pyrazines.
