Diamond Hazard Value Description
1 0
Health   1 Exposure would cause irritation with only minor residual injury (e.g. acetone, sodium bromate, potassium chloride)
Flammability   3 Liquids and solids (including finely divided suspended solids) that can be ignited under almost all ambient temperature conditions . Liquids having a flash point below 22.8 °C (73 °F) and having a boiling point at or above 37.8 °C (100 °F) or having a flash point between 22.8 and 37.8 °C (73 and 100 °F). (e.g. gasoline, acetone)

Chemical Properties

colourless liquid

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.


Raw material for pharmaceutical preparations; organic synthesis solvent.


ChEBI: 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.

General Description

A colorless liquid with a mild to moderately strong odor. Less dense than water. Flash point 91°F. Boiling point 280°F. Vapors heavier than air. Moderately toxic by ingestion. Vapors may irritate skin and eyes. Used as a solvent and to make other chemicals.
Pentanol is incompatible with strong oxidising agents, alkali metals, alkaline earth metals, halogens, hydrogen trisulphide, acids, acetaldehyde, acid anhydrides, acid chlorides, lithium aluminium hydride, isocyanates, dialkylmagnesiums, n-halomides, ethylene oxide, hypochlorous acid, hydrogen peroxide and sulphuric acid, nitrogen tetraoxide, nitryl hypochlorite, permonosulphuric acid, and tri-isobutyl aluminium.

Air & Water Reactions

Highly flammable. Soluble in water.

Reactivity Profile

Moderately toxic, flammable if exposed to powerful oxidizers. Incompatible with oxidizing materials, hydrogen trisulfide [Sax, 9th ed., 1996, p. 224].


Lower explosive level in air 1.2% by vol- ume. Moderate fire risk.

Health Hazard

Irritation of skin, eyes, and respiratory tract; headache and vertigo; dyspnea and cough; nausea, vomiting, and diarrhea. Double vision, deafness, delirium, and occasionally fatal poisoning, preceded by severe nervous symptoms, have been reported. Coma, glycosuria, and methemoglobinemia can occur.

Fire Hazard

HIGHLY FLAMMABLE: Will be easily ignited by heat, sparks or flames. Vapors may form explosive mixtures with air. Vapors may travel to source of ignition and flash back. Most vapors are heavier than air. They will spread along ground and collect in low or confined areas (sewers, basements, tanks). Vapor explosion hazard indoors, outdoors or in sewers. Runoff to sewer may create fire or explosion hazard. Containers may explode when heated. Many liquids are lighter than water.

Safety Profile

Moderately toxic by ingestion and skin contact. An eye and upper respiratory irritant by inhalation. A severe skin and eye irritant. Ingestion can cause headache, nausea, vomiting, delirium, and methemoglobin formation. Mutation data reported. Extremely flammable if exposed to heat, flame, or powerful oxiduers. Moderately explosive when exposed to flame. Incompatible with oxidzing materials, hydrogen trisulfide. To fight fire, use alcohol foam, dry chemical.

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.


UN2811 Pentanols, Hazard Class: 3; Labels: 3- Flammable liquid. UN1987 Alcohols, n.o.s., Hazard Class: 3; Labels: 3-Flammable liquid.

Purification Methods

Dry 1-pentanol with anhydrous K2CO3 or CaSO4, filter and fractionally distil it. It has also been treated with 1-2% of sodium and heated at reflux for 15hours to remove water and chlorides. Traces of water can be removed from the near-dry alcohol by refluxing it with a small amount of sodium in the presence of 2-3% n-amyl phthalate or succinate followed by distillation (see ethanol). Small amounts of amyl alcohol have been purified by esterifying with p-hydroxybenzoic acid, recrystallising the ester from CS2, saponifying with ethanolic-KOH, drying with CaSO4 and fractionally distilling [Olivier Recl Trav Chim Pays-Bas 55 1027 1936]. [Beilstein 1 IV 1640.]


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.

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.
