Hazard Information

Potential Exposure
(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.
First aid
Skin contact contributes significantly to overall exposure. If this chemical gets into the eyes, remove any contact lenses at once and irrigate immediately for at least 15 minutes, occasionally lifting upper and lower lids. Seek medical attention immediately. If this chemical contacts the skin, remove contaminated clothing and wash immediately with soap and water. Seek medical attention immediately. If this chemical has been inhaled, remove from exposure, begin rescue breathing (using universal precautions, including resuscitation mask) if breathing has stopped and CPR if heart action has stopped. Transfer promptly to a medical facility. When this chemical has been swallowed, get medical attention. Give large quantities of water and induce vomiting. Do not make an unconscious person vomit.
Shipping
UN2811 Pentanols, Hazard Class: 3; Labels: 3- Flammable liquid. UN1987 Alcohols, n.o.s., Hazard Class: 3; Labels: 3-Flammable liquid.
Incompatibilities
Forms an explosive mixture with air. Contact with strong oxidizers and hydrogen trisulfide may cause fire and explosions. Incompatible with strong acids. Violent reaction with alkaline earth metals forming hydrogen, a flammable gas.
Chemical Properties
Amyl alcohols (pentanols) have eight isomers. All are flammable, colorless liquids, except the isomer 2,2- dimethyl-1-propanol, which is a crystalline solid.
Chemical Properties
colorless waxy crystalline solid
Waste Disposal
Dissolve or mix the material with a combustible solvent and burn in a chemical incinerator equipped with an afterburner and scrubber. All federal, state, and local environmental regulations must be observed.
Purification Methods
It is difficult to distil because it is a solid at ambient temperatures. Purify it by fractional crystallisation and sublimation. [Beilstein 1 IV 1690.]
