Potassium tert-butyl malonate(CAT: I040497) is an organopotassium compound featuring a malonic acid core esterified with a tert-butyl group and deprotonated to form a potassium salt. It is widely used as a versatile intermediate in organic synthesis, particularly in alkylation, decarboxylation, and condensation reactions. The tert-butyl ester provides steric protection and enhanced solubility in organic solvents, while the potassium salt form improves reactivity and handling. Potassium tert-butyl malonate is ideal for synthesizing substituted malonic acid derivatives, pharmaceutical building blocks, and functionalized molecules in medicinal chemistry and agrochemical research. Supplied in high purity, it supports efficient and scalable synthetic applications.
