4-Mercaptophthalic acid is an alkaline chemical that is used in the pharmaceutical industry. It can act as a hardener, and is often used in the manufacture of polymers. 4-Mercaptophthalic acid reacts with metal hydroxides to produce alkali metal sulfides, which are soluble in water. 4-Mercaptophthalic acid also reacts with sodium hydroxide to form sodium hydrogen sulfide and hydrogen sulfide gas, which has a strong offensive odor. This chemical has been shown to be harmful if inhaled or ingested, and should be handled with protective equipment.
