3-Chloro-5-hydroxybenzoic acid (C7H5ClO3) is a derivative of benzoic acid with a chlorine atom and a hydroxyl group attached to the benzene ring. It acts as a selective agonist of the lactate receptor, GPR81 (FKSG80), which plays a role in regulating triglyceride lipolysis in adipose tissue. With its acidic and phenolic properties, this compound is versatile in participating in esterification, condensation, and other organic transformations.
