2-Butynedioic acid, potassium salt (1:1)

Description:
2-Butynedioic acid, potassium salt (1:1), also known as potassium 2-butynoate, is a chemical compound characterized by its role as a salt derived from 2-butynedioic acid. It typically appears as a white to off-white crystalline solid and is soluble in water, which facilitates its use in various applications. The compound features a dicarboxylic acid structure, with two carboxylate groups (-COO⁻) that are deprotonated in the salt form, allowing it to participate in various chemical reactions. Its potassium salt form enhances its stability and solubility compared to the free acid. This compound is often utilized in organic synthesis, particularly in the production of other organic compounds, and may also have applications in agriculture as a potential herbicide or plant growth regulator. Additionally, it can serve as a precursor in the synthesis of various pharmaceuticals and fine chemicals. Safety data should be consulted for handling and usage, as with any chemical substance.
