content analysisdetermined through non-polar column method of gas chromatography(GT-10-4).
Toxicity  GRAS (FEMA).
Use limits
FEMA (mg/kg): soft drinks 17; cold drinks 7.6; candy 52; baked goods 24; pudding 46; gum 300; alcohol 100. Modest limit (FDA § 172.515, 2000).
Uses(1) Used as food flavors according to GB 2760-96. Mainly used for the preparation of apple and banana flavor.
(2) Used as chromatographic reagent and extractant, and also used in the pharmaceutical industry
(3) Used in the manufacture of spices, pharmaceuticals and mineral processing agents, and also used as solvents
(4) This goods have apple brandy aroma and spicy flavor. China's GB 2760-86 provides for its allowable use as food spices, mainly for the preparation of apple and banana flavor. Isoamyl alcohol and sodium nitrite can perform esterification to form isoamyl nitrite, which is the fastest nitrous esters short-acting vasodilator. Isoamyl alcohol can be used to synthesize sedatives and hypnotics, such as bromural and amytal. Isoamyl alcohol can also be used as solvents and the reagents for chemical analysis. It is also used as the raw materials to produce plasticizers and photographic pharmaceutical. In addition, it is one component of the fuel oil.
(5) Used for the manufacture of spices, pharmaceuticals and photographic drugs, and also used as solvents.
(6) Used as the solvents of fat, resin and alkaloid. Used for the determination of fat in milk and the determination of iron, silicon, thorium and fusel oil. Also used for the complexation extraction of iron, cobalt, copper salt and diphenylcarbazide. Used for the separation of lithium Chloride from other alkali metal chlorides.
Production methods(1) This product naturally presents in the form of esters in strawberries, peppermint, lemongrass, eucalyptus oil and rum and so on. It can be synthesized by acid method or the hydroformylation of C4 alkenes. 3-methyl-1-butanol (85% in the fusel oil) can be obtained by chemical treatment and distillation separation of the fusel oil that is the side products form the alcohol fermentation of starch and sugar.
(2) Derived from fusel oil fractionation.
Pentane performs chlorination and hydrolysis reaction to form mixed alcohol, and then isoamyl alcohol can be derived from the mixed alcohol.

Chemical PropertiesAmyl alcohols (pentanols) have eight isomers. All are flammable, colorless liquids, except the isomer 2,2- dimethyl-1-propanol, which is a crystalline solid.
Chemical Propertiescolourless liquid
UsesIsoamylol is one of the several isomers of amyl alcohol and the main ingredient in the production of banana oil.
DefinitionChEBI: An alkyl alcohol that is butan-1-ol substituted by a methyl group at position 3.
UsesSolvent for fats, resins, alkaloids, etc.; manufacture of isoamyl (amyl) Compounds, isovaleric acid, mercury fulminate, pyroxylin, artificial silk, lacquers, smokeless powders; in microscopy; for dehydrating celloidin solutions; for determining fat in milk.
General DescriptionColorless liquid with a mild, choking alcohol odor. Less dense than water, soluble in water. Hence floats on water. Produces an irritating vapor.
Air & Water ReactionsHighly flammable. Water soluble.
Reactivity Profile3-Methyl-1-butanol attacks plastics [Handling Chemicals Safely, 1980. p. 236]. Mixtures with concentrated sulfuric acid and strong hydrogen peroxide may cause explosions. Mixing with hypochlorous acid in water or water/carbon tetrachloride solution can generate isoamyl hypochlorites, which may explode, particularly on exposure to sunlight or heat. Mixing with chlorine would also yield isoamyl hypochlorites [NFPA 491 M, 1991]. Base-catalysed reactions with isocyanates can occur with explosive violence [Wischmeyer,1969].
HazardModerate fire risk. Vapor is toxic and irritant. Explosive limits in air 1.2–9%.
Health HazardVery high vapor concentrations irritate eyes and upper respiratory tract. Continued contact with skin may cause irritation.
Fire HazardFlash Point (°F): 114 ℃; Flammable Limits in Air (%): 1.2-9.0; Fire Extinguishing Agents: Water spray, dry chemical, alcohol foam, or carbon dioxide; Fire Extinguishing Agents Not To Be Used: Not pertinent; Special Hazards of Combustion Products: Not pertinent; Behavior in Fire: Not pertinent; Ignition Temperature (°F): 662; Electrical Hazard: Class I, Group C; Burning Rate: 3.6 mm/min.
Chemical ReactivityReactivity with Water: No reaction; Reactivity with Common Materials: No reactions; Stability During Transport: Stable; Neutralizing Agents for Acids and Caustics: Not pertinent; Polymerization: Not pertinent; Inhibitor of Polymerization: Not pertinent.
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 aidSkin 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.
ShippingUN2811 Pentanols, Hazard Class: 3; Labels: 3- Flammable liquid. UN1987 Alcohols, n.o.s., Hazard Class: 3; Labels: 3-Flammable liquid.
Purification MethodsDry the alcohol by heating with CaO and fractionally distilling, then heating with BaO and redistilling. Alternatively, boil it with concentrated KOH solution, wash it with dilute H3PO4, and dry it with K2CO3, then anhydrous CuSO4, before fractionally distilling it. If very dry alcohol is required, the distillate is refluxed with the appropriate alkyl phthalate or succinate as described for ethanol. It is separated from 2-methyl-1-butanol by fractional distillation, fractional crystallisation and preparative gas chromatography. [Beilstein 1 IV 1677.]
IncompatibilitiesForms 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 DisposalDissolve 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.
