[1] [2] In physical and analytical chemistry, infrared spectroscopy (IR spectroscopy) is a technique used to identify chemical compounds based on the way infrared radiation is absorbed by the compound. The absorptions in this range do not apply only to bonds in organic molecules.
Isovaleric acid, also known as 3-methylbutanoic acid or β-methylbutyric acid, is a branched-chain alkyl carboxylic acid with the chemical formula (CH 3) 2 CHCH 2 CO 2 H. It is classified as a short-chain fatty acid. Like other low-molecular-weight carboxylic acids, it has an unpleasant odor. The compound occurs naturally and can be found in ...
Methyl butyrate, also known under the systematic name methyl butanoate, is the methyl ester of butyric acid. Like most esters, it has a fruity odor, in this case resembling apples or pineapples. [2] At room temperature, it is a colorless liquid with low solubility in water, upon which it floats to form an oily layer.
Infrared spectroscopy (IR spectroscopy or vibrational spectroscopy) is the measurement of the interaction of infrared radiation with matter by absorption, emission, or reflection. It is used to study and identify chemical substances or functional groups in solid, liquid, or gaseous forms. It can be used to characterize new materials or identify ...
Ethyl 3-methylbutanoate. Other names Butanoic acid, 3-methyl-, ethyl ester. Identifiers CAS Number. 108-64-5 ...
The strongest line in the infrared spectrum is at 1330 cm −1 followed by lines at 3010 cm −1 and 1185 cm −1. Its melting point is −161.5 °C, and its boiling point is −20.2 °C. Vapour pressure is given by log P = 6.1385 + 1.75 log T − 1393.3/ T − 0.007735 T , where T is temperature in kelvins . [ 5 ]
Isoamyl alcohol is a colorless liquid with the formula C 5 H 12 O, specifically (H 3 C–) 2 CH–CH 2 –CH 2 –OH. It is one of several isomers of amyl alcohol (pentanol). It is also known as isopentyl alcohol, isopentanol, or (in the IUPAC recommended nomenclature) 3-methyl-butan-1-ol.
3-Methyl-3-pentanol (IUPAC name: 3-methylpentan-3-ol) is an organic chemical compound and a tertiary hexanol. It is used in the synthesis of the tranquilizer emylcamate , [ 2 ] and has similar sedative and anticonvulsant actions itself.
