Formaldehyde (/ f ɔːr ˈ m æ l d ɪ h aɪ d / ⓘ for-MAL-di-hide, US also / f ə r-/ ⓘ fər-) (systematic name methanal) is an organic compound with the chemical formula CH 2 O and structure H−CHO, more precisely H 2 C=O. The compound is a pungent, colourless gas that polymerises spontaneously into paraformaldehyde.
Aldehyde. In organic chemistry, an aldehyde ( / ˈældɪhaɪd /) is an organic compound containing a functional group with the structure R−CH=O. [ 1] The functional group itself (without the "R" side chain) can be referred to as an aldehyde but can also be classified as a formyl group.
Choline occurs in foods as a free molecule and in the form of phospholipids, especially as phosphatidylcholines. Choline is highest in organ meats and egg yolks though it is found to a lesser degree in non-organ meats, grains, vegetables, fruit and dairy products. Cooking oils and other food fats have about 5 mg/100 g of total choline. [8]
Acetaldehyde (IUPAC systematic name ethanal) is an organic chemical compound with the formula CH 3 CHO, sometimes abbreviated as Me CHO. It is a colorless liquid or gas, boiling near room temperature. It is one of the most important aldehydes, occurring widely in nature and being produced on a large scale in industry.
Butyraldehyde, also known as butanal, is an organic compound with the formula CH 3 (CH 2) 2 CHO. This compound is the aldehyde derivative of butane. It is a colorless flammable liquid with an unpleasant smell. It is miscible with most organic solvents.

Benzaldehyde (C 6 H 5 CHO) is an organic compound consisting of a benzene ring with a formyl substituent. It is among the simplest aromatic aldehydes and one of the most industrially useful. It is a colorless liquid with a characteristic almond -like odor, and is commonly used in cherry -flavored sodas. [ 5]
Choline hydroxide is a quaternary ammonium salt, consisting of choline cations ( [ (CH3)3NCH2CH2OH]+) and hydroxide anions ( OH− ). It is bifunctional compound, meaning, it contains both quaternary ammonium functional group and a hydroxyl functional group. Choline hydroxide forms an ionic liquid .
