4-Hydroxybut-2-ynoic acid

Description:

4-Hydroxybut-2-ynoic acid, also known as 4-hydroxy-2-butyne-1,2-dioic acid, is an organic compound characterized by its unique structure, which includes a hydroxyl group and a triple bond within a butynoic acid framework. This compound features a carboxylic acid functional group, contributing to its acidic properties. It is typically a colorless to pale yellow solid at room temperature and is soluble in polar solvents due to the presence of the hydroxyl and carboxylic acid groups. The compound is known for its reactivity, particularly in condensation reactions and as a potential building block in organic synthesis. Its applications may extend to the fields of pharmaceuticals and materials science, where it can serve as an intermediate in the synthesis of more complex molecules. Safety data indicates that, like many organic acids, it should be handled with care, as it may cause irritation to skin and eyes. Proper storage and handling protocols are essential to ensure safety in laboratory settings.
