propenylisulfonihappo

Propenylisulfonihappo, also known as allylsulfonic acid, is an organosulfur compound with the chemical formula C3H6SO3. It features a propenyl group (an allyl group) attached to a sulfonic acid group. This molecule is characterized by its unsaturated carbon chain and the strongly acidic sulfonic acid moiety. The structure can be represented as CH2=CHCH2SO3H.

Propenylisulfonihappo is a strong acid due to the presence of the sulfonic acid group, which readily donates a proton. Its reactivity is influenced by both the double bond and the sulfonic acid group. The double bond can undergo addition reactions, characteristic of alkenes, while the sulfonic acid group can participate in reactions typical of strong acids, such as salt formation.

This compound has found applications in various chemical processes. It can be used as a monomer in the synthesis of polymers, imparting specific properties such as increased hydrophilicity or ion-exchange capacity to the resulting materials. It has also been explored as an intermediate in the production of specialty chemicals and pharmaceuticals. Due to its acidic nature, handling and storage require appropriate safety precautions.
