Antimony Potassium Tartrate, also known as Tartar Emetic, is a specialty chemical used in various applications. In the textile industry, it serves as a mordant in dyeing processes to fix dyes to fabrics, ensuring vibrant and long-lasting colors. It has historical use in agriculture as a pesticide, particularly for controlling insect pests in fruit orchards and field crops. Medically, it was employed in the treatment of parasitic infections such as schistosomiasis as an antiparasitic agent and as an emetic to induce vomiting in poisoning cases. However, its use is now limited due to high toxicity. It is also used in the manufacturing of other antimony-based compounds.
