Potassium Chlorate Extra Pure

SHORT DESCRIPTION Potassium Chlorate Extra Pure is a high-purity, crystalline compound with the chemical formula KClO₃. It appears as a white, odorless solid and is well known for its strong oxidizing properties. In its Extra Pure form, it meets analytical-grade standards, making it suitable for sensitive laboratory and controlled industrial applications. This chemical is extensively used in analytical chemistry, especially in oxygen production experiments and thermal decomposition studies, as it decomposes to release oxygen when heated. It is also used as a reagent in pyrotechnics, match compositions, and explosive formulations, where a powerful oxidizer is needed. In botanical tissue culture, potassium chlorate is sometimes used to induce flowering in certain plant species. Due to its reactive and potentially explosive nature, Potassium Chlorate must be handled with extreme caution. It should be stored away from combustible materials, acids, and heat sources, in a cool, dry, well-ventilated area, in tightly sealed containers. Personal protective equipment such as gloves, goggles, and lab coats must be worn during handling, and it should never be ground or mixed with sulfur, phosphorus, or organic matter unless under strictly controlled conditions.
