Isoamyl alcohol

Isoamyl alcohol (CAS 123-51-3) is a clear, colorless liquid with a characteristic pungent, chloroform-like odor and moderate volatility; it has a boiling point of approximately 130 °C and a melting point near −12 °C. It is classified as a branched-chain aliphatic primary alcohol and an organic chemical intermediate. Industrially, it serves primarily as a precursor in the synthesis of isoamyl acetate (a key flavor and fragrance ester), as well as in the production of plasticizers, lubricant additives, and pharmaceutical intermediates. Its applications span flavors and fragrances, coatings, agrochemical formulations, and specialty solvents where moderate polarity and low water solubility are advantageous.

(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.
