Verwenden
3-Methyl-2-butanol has been used as a reference for microbially produced, volatile organic compounds (MVOC) in GC-MS analyses.
Definition
ChEBI: A secondary alcohol that is 2-butanol carrying an additional methyl substituent at position 3.
Hazard
Moderately toxic.
mögliche Exposition
(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.
