Pentan-3-ol. Other names 3-Pentanol, diethyl carbinol ... 3-Pentanol is one of the eight isomers of amyl alcohol. It is found naturally and has a role as a pheromone ...
Three of these alcohols, 2-methyl-1-butanol, 2-pentanol, and 3-methyl-2-butanol (methyl isopropyl carbinol), contain stereocenters, and are therefore chiral and optically active. The most important amyl alcohol is isoamyl alcohol , the chief one generated by fermentation in the production of alcoholic beverages and a constituent of fusel oil .
Configuration assignment of the stereo center "X", the substituents are decreasingly prioritized from "A" → "D" according to the CIP rules. The stereochemical descriptors (R) (from Latin rectus = right) and (S) (from lat. sinister = left) [36] are used to describe the absolute configuration of a stereocenter (usually a chiral carbon atom). [37]
2-Pentanol (IUPAC name: pentan-2-ol; also called sec-amyl alcohol) is an organic chemical compound.It is used as a solvent and an intermediate in the manufacturing of other chemicals. 2-Pentanol is a component of many mixtures of amyl alcohols sold industrially. 2-Pentanol is chiral and thus can be obtained as either of two stereoisomers designated as (R)-(−)-2-pentanol and (S)-(+)-2-pentanol.
Pentyl is a five-carbon alkyl group or substituent with chemical formula-C 5 H 11.It is the substituent form of the alkane pentane.. In older literature, the common non-systematic name amyl was often used for the pentyl group.
Isoamyl alcohol is a colorless liquid with the formula C 5 H 12 O, specifically (H 3 C–) 2 CH–CH 2 –CH 2 –OH. It is one of several isomers of amyl alcohol (pentanol). It is also known as isopentyl alcohol, isopentanol, or (in the IUPAC recommended nomenclature) 3-methyl-butan-1-ol.
3-Methyl-3-pentanol (IUPAC name: 3-methylpentan-3-ol) is an organic chemical compound and a tertiary hexanol. It is used in the synthesis of the tranquilizer emylcamate , [ 2 ] and has similar sedative and anticonvulsant actions itself.
The optical center is the middle carbon of the pentane backbone, which is connected to one hydrogen atom, one methyl group, one ethyl group – C 2 H 5, and one isopropyl group – CH(CH 3) 2. The two enantiomers are denoted (3R)-2,3-dimethylpentane and (3S)-2,3-dimethylpentane (the other simplest chiral alkane is its structural isomer 3 ...
