The United States FDA considers citronellol as generally recognized as safe (GRAS) for food use. [7] Citronellol is subject to restrictions on its use in perfumery, [8] as some people may become sensitised to it, but the degree to which citronellol can cause an allergic reaction in humans is disputed.
The structure of a nitrile: the functional group is highlighted blue. In organic chemistry, a nitrile is any organic compound that has a −C≡N functional group.The name of the compound is composed of a base, which includes the carbon of the −C≡N, suffixed with "nitrile", so for example CH 3 CH 2 C≡N is called "propionitrile" (or propanenitrile). [1]
Citronellal or rhodinal (C 10 H 18 O) is a monoterpenoid aldehyde, the main component in the mixture of terpenoid chemical compounds that give citronella oil its distinctive lemon scent.
Hydroxycitronellal (7-hydroxy-3,7-dimethyloctanal) is an odorant used in perfumery. [1] Its molecular formula is C 10 H 20 O 2. [2] [3] [4]It derives from a citronellal. 7-Hydroxy-3, 7-dimethyloctanal, also known as 3, 7-dimethyl-7-hydroxyoctan-1-al or 7-hydroxycitronellal, belongs to the class of organic compounds known as medium-chain aldehydes.
Linalool is hydrogenated to give dihydro- and tetrahydrolinalool, which are fragrances that are more resilient toward oxidants, as might be found in household cleaning products. Linalyl acetate, a popular scent, is produced by esterification of linalool (as well as occurring naturally). Isomerization of linalool gives geraniol and nerol. [2]
This is a static list of 599 additives that could be added to tobacco cigarettes in 1994. The ABC News program Day One first released the list to the public on March 7, 1994. [1]
The first compound of this class was introduced 1975 with Cyclomusk, though similar structures were noted earlier in citronellyl oxalate and Rosamusk. [7] Alicyclic musks are dramatically different in structure than previous musks (aromatic, polycyclic, macrocyclic) in that they are modified alkyl esters. [ 8 ]
The determining factor is typically how electron-rich or poor the nitrile is. For example: an electron-poor nitrile is a good electrophile (readily susceptible to attack from alkoxides etc.) but a poor nucleophile would typically be easier to protonate than to participate in the reaction and hence would be expected to react more readily under ...
