colourless liquid??
3-Pentanol is widely used as a flavoring agent. It is biogenic oxygenated volatile organic compound (BOVOC) and is used as a reagent in the synthesis of pure bromopentanes for infrared standards.??
ChEBI: A secondary alcohol that is pentane substituted at position 3 by a hydroxy group.??? ??
(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.?? ??
