Potassium Iodide SQ 500g Qualigens

Qualigens Potassium Iodide (SQ) is a white, crystalline powder that appears as cubical crystals, granules, or powder, with an odorless profile and a characteristic bitter, saline taste. It is a chemical compound consisting of potassium cations (K+) and iodide anions (I). This product is classified as "SQ" (Standard Grade or Superior Quality), indicating it meets high purity standards, with an assay typically at least 99%. It is also a hygroscopic substance, meaning it absorbs moisture from the air, and is light-sensitive, requiring storage in tightly closed, dark containers to prevent degradation and discoloration from elemental iodine formation. Key Characteristics
