Description

clear liquid Amyl alcohols (pentanols) have eight isomers. All are flammable, colorless liquids, except the isomer 2,2- dimethyl-1-propanol, which is a crystalline solid.

clear liquid

ChEBI: Pentan-1-ol is an alkyl alcohol that is pentane in which a hydrogen of one of the methyl groups is substituted by a hydroxy group. It has been isolated from Melicope ptelefolia. It has a role as a plant metabolite. It is an alkyl alcohol, a primary alcohol, a pentanol and a short-chain primary fatty alcohol.

(n-isomer); Suspected reprotoxic hazard, Primary irritant (w/o allergic reaction), (iso-, primary): Possible risk of forming tumors, Primary irritant (w/o allergic reaction), (sec-, active primary-, and other isomers) Primary irritant (w/o allergic reaction). Used as a solvent in organic synthesis and synthetic flavoring, pharmaceuticals, corrosion inhibitors; making plastics and other chemicals; as a flotation agent. The (n-isomer) is used in preparation of oil additives, plasticizers, synthetic lubricants, and as a solvent.

ISOAMYL ALCOHOL Use and Manufacturing

Pentyl alcohol can be used in organic synthesis, as a solvent for coatings, a raw material for pharmaceuticals, a flotation agent for non-ferrous metals, and an antifoaming agent for boiler water. It can also be used to manufacture amyl acetate. Mixtures of pentyl alcohol with other solvents can be used as co-solvents for nitrocellulose lacquer and for extracting resin from wood.

Isoamyl alcohol is a clear, colorless alcohol. It is one of several isomers of amyl alcohol. It is commonly used as a solvent in various applications, such as inks, coatings, and pharmaceutical preparations.
