Zinc Oxide Extra Pure is a high-purity, white, fine powder used extensively in laboratory, research, and pharmaceutical-grade formulations. Renowned for its amphoteric character, it reacts with both acids and bases, making it highly versatile in chemical synthesis and pH-related experiments. In laboratory research, it plays a key role in analytical chemistry, photocatalysis, pigment studies, and semiconducting material research. It is also valued in pharmaceutical and cosmetic R&D for its antimicrobial, UV-reflective, and healing properties. In environmental and materials science labs, Zinc Oxide is studied for its potential in pollutant degradation, corrosion resistance, and nanomaterial development. Its Extra Pure grade ensures suitability for applications demanding precise, consistent purity and low impurity levels. Although generally safe to handle, care should be taken to avoid inhaling fine dust or releasing large amounts into aquatic environments due to its toxicity to aquatic life.
