CH3CH26CHO

CH3CH26CHO appears to be a typographical or structural error, as the notation does not correspond to a valid chemical formula. The correct formula for a three-carbon aldehyde with the given structure would likely be CH3CH2CHO, commonly known as propanal. Below is a concise description of propanal for clarity.

Propanal, also referred to as ethyl aldehyde or propaldehyde, is an organic compound with the chemical formula CH3CH2CHO. It is a colorless liquid with a pungent, fruity odor, similar to that of apples. Propanal belongs to the class of aldehydes, characterized by the presence of a carbonyl group (C=O) bonded to a hydrogen atom and an alkyl or aryl group.

Propanal is produced industrially through the oxidation of propene or the hydrolysis of 1,1-dichloropropane. It is also found naturally in small quantities in various fruits and vegetables, contributing to their aroma. In the laboratory, propanal can be synthesized via the oxidation of primary alcohols, such as propanol, using oxidizing agents like potassium permanganate or pyridinium chlorochromate.

The compound is soluble in water and organic solvents and is used primarily as an intermediate in the synthesis of other chemicals, including pharmaceuticals, perfumes, and agrochemicals. Due to its reactivity, propanal can undergo various chemical reactions, such as aldol condensation, oxidation to propanoic acid, and reduction to propanol.

While propanal is generally considered safe in low concentrations, higher exposures may cause irritation to the skin, eyes, and respiratory tract. Proper handling and ventilation are recommended when working with this compound.
