OHCCH23CHO

OHCCH23CHO, often written as OHC-CH2-CH2-CHO, is an organic compound that belongs to the class of dialdehydes. It is commonly referred to as 1,4-butanedial or succinaldehyde. The chemical formula is C4H6O2, and its systematic name is butane-1,4-dial.

Structure and properties: OHCCH23CHO is a straight-chain dialdehyde with aldehyde groups at both ends. The molecule comprises a four-carbon backbone with two formyl groups. It typically exists as a colorless liquid at room temperature, has a sharp aldehydic odor, and is soluble in many organic solvents. It is reactive toward nucleophiles such as amines, alcohols, and mercaptans, enabling a range of condensation and addition reactions.

Synthesis and sources: Industrially, succinaldehyde is produced as a chemical intermediate by the oxidation of 1,4-butanediol or by oxidation of succinic derivatives. It is mainly used as a building block in the preparation of resins, crosslinkers, and other organic synthesis intermediates.

Reactions: The dialdehyde readily undergoes aldol condensations, imine formation with amines, and acetalization with diols. It can participate in polymerization processes as a crosslinking agent and serves as a versatile C4 dialdehyde in various synthetic schemes.

Safety and handling: OHCCH23CHO is a hazardous chemical. It can be irritating to skin, eyes, and the respiratory tract and should be handled in a well-ventilated area with appropriate personal protective equipment. It is reactive and should be stored away from oxidizers, heat, and moisture to minimize decomposition or unintended reactions.
