2-Butenedioic acid (2E)-, potassium salt (1:?)

Description:
2-Butenedioic acid (2E)-, potassium salt, commonly known as potassium maleate, is a potassium salt of maleic acid. It is characterized by its white crystalline appearance and is soluble in water, making it useful in various applications. The compound features a dicarboxylic acid structure, which contributes to its reactivity and ability to form complexes with metal ions. Potassium maleate is often utilized in agricultural settings as a fertilizer and in the food industry as a food additive due to its acidity regulator properties. Additionally, it can serve as a precursor in organic synthesis and as a buffering agent in biochemical applications. The compound is generally regarded as safe when used appropriately, but like many chemicals, it should be handled with care to avoid potential irritation or adverse reactions. Its stability and reactivity can vary depending on environmental conditions, such as pH and temperature, which are important considerations in its practical applications.
