Potassium phthalimide potassium salt (English name phthalimide) also known as potassium phthalimide, 1, 3-dihydro-1, potassium 3-dioxoisoindole potassium salt (1,3-dihydro-1,3-dioxoisoindole) is white crystalline or white flake powder at room temperature. Soluble in water, insoluble in ethanol, acetone. There is a lack of research data on its toxicity and pathology. This product has an irritating effect on eyes, skin, mucous membranes and digestive tract, and can cause skin allergy. The manufacturer of phthalimide potassium salt suggests that skin contact or entering eyes should be avoided, and a large amount of water should be used to rinse once contact is made. The operating environment should be well ventilated to avoid dust accumulation or inhalation. This product is flammable, high temperature, open fire combustion decomposition will release smoke and nitrogen oxide and other toxic gases. Widely used in the production of medicine, pesticides, dyes, synthesis of primary amine compounds. The molecular formula is C8H4KNO2.
