Isoamyl Alcohol, commonly known as Isopentanol or 3-methyl-butan-1-ol, is a colorless liquid with the formula C5H12O. It is one of many isomers of pentyl alcohol and was previously known as isobutyl carbinol. It is a common fusel alcohol produced as a by-product of ethanol production. Lab Grade is also known as Laboratory Reagent (LR) and Chemically Pure (CP). Lab grade chemicals possess reasonable purity but do not comply with any official standards for quality or purity like the ACS Grade, the USP Grade, or the FCC Grade. Lab Alley’s premium grade Isoamyl Alcohol, Lab Grade is highly recommended for educational institutes and research laboratories. Lab Alley is selling its premium quality products online at in the United States of America (USA).

Information On Isoamyl Alcohol From Wikipedia

Isoamyl alcohol (also known as isopentyl alcohol) is a colorless liquid with the formula (CH3)2CHCH2CH2OH. It is one of several isomers of amyl alcohol. It is an ingredient in the production of banana oil, an ester found in nature and also produced as a flavouring in industry. It is a common fusel alcohol, produced as a major by-product of ethanol fermentation. It is also an ingredient of Kovac's reagent, used for the bacterial diagnostic indole test. It is also used as an antifoaming agent in the chloroform:isomyl alcohol reagent. Isoamyl alcohol is used in a phenol–chloroform extraction mixed with the chloroform to further inhibit RNase activity and prevent solubility of RNAs with long tracts of poly-adenine. It is one of the components of the aroma of Tuber melanosporum, the black truffle. It has been identified as a chemical in the pheromone used by hornets to attract other members of the hive to attack.

Information About Isoamyl Alcohol From PubChem

Isoamyl alcohol is a colorless liquid with a mild, choking alcohol odor. Less dense than water, soluble in water. Hence floats on water. Produces an irritating vapor. Isopentanol or Isoamyl alcohol is one of several isomers of amyl alcohol. It is a by-product of gut microbial fermentation (PMID: 17452087). It can be produced by 3-methylbutanal reductase (EC 1. 1. 1. 265) from 3 methylbutanal. Isoamyl alcohol is the major higher chain alcohol in alcoholic beverages and is present in cider, mead, beer, wine, and spirits to varying degrees, being obtained by the fermentation of starches. Isopentanol has been shown to induce expression of CYP3A and CYP2E1 in human liver(PMID: 7574728). Isoamylol is an primary alcohol that is butan-1-ol in which a hydrogen at position 3 has been replaced by a methyl group. It has a role as a xenobiotic metabolite, a Saccharomyces cerevisiae metabolite and an antifungal agent. It is a primary alcohol, a volatile organic compound and an alkyl alcohol. It derives from a hydride of an isopentane.
