590-93-2 - Application:

2-Butynoic Acid (Tetrolic Acid) (CAS: 590-93-2) is used as an intermediate in organic synthesis and pharmaceuticals. It is used as a synthon in various reactions, which includes cylcoalkylation of phenols to flavones and chromones. It is involved in the cyclization of gamma-butyrolactones.
2-Butynoic Acid has the dual characteristics of alkynes and carboxylic acids, and can carry out reduction, addition, oxidation, esterification and cyclization, and the formation of salts and acid chlorides.
Used in a series of reactions to synthesize fibers, such as the cyclic acylation of phenols to cyclic ketones or chromones, and the cyclization of γ-butyrolactone.
2-Butynoic Acid can be used for the preparation of dibromocrotonic acid, ethoxycrotonic acid, butynic acid ethyl ester, butynyl (acid) chloride and butynyl (acid) amide.
