Butanal
Butanal, also known as butyral or butyl aldehyde, belongs to the class of organic compounds known as alpha-hydrogen aldehydes. These are aldehydes with the general formula HC(H)(R)C(=O)H, where R is an organyl group. It is miscible with most organic solvents. Butanal exists in all living organisms, ranging from bacteria to humans. Upon prolonged exposure to air, butyraldehyde oxidizes to form butyric acid. Butanal is an apple, bready, and chocolate tasting compound. Outside of the human body, Butanal is found, on average, in the highest concentration within cow milk and carrots. Butanal has also been detected, but not quantified in several different foods, such as hard wheats, borages, ostrich ferns, skunk currants, and fennels. This could make butanal a potential biomarker for the consumption of these foods. The dominant technology involves the use of rhodium catalysts derived from the water-soluble ligand Tppts. Butyraldehyde is produced almost exclusively by the hydroformylation of propylene:CH3CHCH2 + H2 + CO → CH3CH2CH2CHO. Traditionally, hydroformylation was catalyzed by cobalt carbonyl and later rhodium complexes of triphenylphosphine. At one time, it was produced industrially by the catalytic hydrogenation of crotonaldehyde, which is derived from acetaldehyde. Butyraldehyde can be produced by the catalytic dehydrogenation of n-butanol. This compound is the aldehyde derivative of butane. An aqueous solution of the rhodium catalyst converts the propylene to the aldehyde, which forms a lighter immiscible phase. About 6 billion kilograms are produced annually by hydroformylation. It is a colourless flammable liquid with an unpleasant smell. Occurs in essential oils, e.g. lavender, hopand is also present in apple, banana, blackberry, hog plum, wheat bread, malt whiskey, red or white wine, tea, toasted oat flakes and other foodstuffs.

Butanone
Butanone occurs as a natural product. It is made by some trees and found in some fruits and vegetables in small amounts. It is also released to the air from car and truck exhausts. The known health effects to people from exposure to butanone are irritation of the nose, throat, skin, and eyes. (wikipedia).
2-Methylpropanal
2-Methylpropanal, also known as isobutylaldehyde or isobutyral, belongs to the class of organic compounds known as short-chain aldehydes. These are aldehydes with a chain length between 2 and 5 carbon atoms. 2-Methylpropanal exists in all eukaryotes, ranging from yeast to humans. 2-Methylpropanal is an aldehydic, floral, and fresh tasting compound. 2-Methylpropanal is found, on average, in the highest concentration within milk (cow). 2-Methylpropanal has also been detected, but not quantified, in several different foods, such as greenthread tea, wheats, common grapes, other cereal products, and oxheart cabbages. Found in tea, beer, sake, brandy, fresh fruits (apple, banana, cherry etc.), breads, cooked pork, and spearmint oil
Tetrahydrofuran
Tetrahydrofuran (THF) is a cyclic ether. It is a colorless, water-miscible organic liquid with low viscosity and a smell similar to diethyl ether. At low concentrations it has a faint, fruity aroma. It is one of the most polar ethers. THF is naturally present in coffee aroma, floured chickpeas, and cooked chicken. It is used in the manufacture of polymers as well as agricultural, pharmaceutical, and commodity chemicals. Because of its widespread use (industrially) and its presence in many foods, THF is a contaminant of exposure and can appear in human biofluids. THF oxidizes readily, which can lead to instability and result in cytotoxicity. In chemical synthesis applications, THF is often used for hydroborations used to synthesize primary alcohols. THF is frequently used as a solvent for Grignard reagents because of the oxygen atoms ability to coordinate to the magnesium ion component of the Grignard reagent (an organometallic chemical reaction involving alkyl- or aryl-magnesium halides). THF is often used in polymer science. For example, it can be used to dissolve rubber prior to determining its molecular mass using gel permeation chromatography. THF tends to form peroxides on storage in air. (PMID: 16999122, 12742700, 14619948). THF can be degraded by certain strains of Rhodococcus bacteria (PMID: 19230656). Tetrahydrofuran (THF) is a contaminant of exposure and appears in human biofluids. The Food and Drug Administration (FDA) has announced recommendations to revise the permitted daily exposures for THF, and so has the International Conference on Harmonisation. THF oxidizes readily, which can lead to instability and result in cytotoxicity. It is a colourless low-viscosity liquid with a smell similar to diethyl ether and is one of the most polar ethers. Tetrahydrofuran is essentially considered in occupational toxicology, and acute poisoning cases are extremely rare. THF is often used for hydroborations used to synthesize primary alcohols. THF is often used as a solvent for Grignard reagents because of the oxygen atoms ability to coordinate to the magnesium ion component of the Grignard reagent (an organometallic chemical reaction involving alkyl- or aryl-magnesium halides). THF is often used in polymer science. For example, it can be used to dissolve rubber prior to determining its molecular mass using gel permeation chromatography. THF tends to form peroxides on storage in air. (wikipedia, PMID: 16999122, 12742700, 14619948) [HMDB]

2-Butanone
A dialkyl ketone that is a four-carbon ketone carrying a single keto- group at position C-2. Butanone, also known as methyl ethyl ketone or mek, is a member of the class of compounds known as ketones. Ketones are organic compounds in which a carbonyl group is bonded to two carbon atoms R2C=O (neither R may be a hydrogen atom). Ketones that have one or more alpha-hydrogen atoms undergo keto-enol tautomerization, the tautomer being an enol. Thus, butanone is considered to be an oxygenated hydrocarbon lipid molecule. Butanone is soluble (in water) and an extremely weak acidic compound (based on its pKa). Butanone is an acetone, camphor, and ethereal tasting compound and can be found in a number of food items such as arctic blackberry, onion-family vegetables, sweet orange, and devilfish, which makes butanone a potential biomarker for the consumption of these food products. Butanone can be found primarily in blood, feces, saliva, and urine, as well as in human pancreas and stratum corneum tissues. Moreover, butanone is found to be associated with alcoholism. Butanone is a non-carcinogenic (not listed by IARC) potentially toxic compound.
