Product Description:

Cadmium iodide (CdI₂) is an inorganic compound with a distinctive layered crystal structure, often serving as a prototype for the cadmium iodide structure type. It appears as white to pale yellow crystals or powder and is highly soluble in water, ethanol, and acetone. Its primary modern applications are in materials science and research. It is a key precursor for the synthesis of cadmium sulfide (CdS) and cadmium selenide (CdSe) nanoparticles and thin films, which are vital semiconductor materials for photovoltaics, light-emitting diodes (LEDs), and photodetectors. In synthetic chemistry, it finds use as a catalyst in specific organic reactions, such as the synthesis of vinyl iodides from alkynes, and as a source of iodide ions. Cadmium iodide is highly toxic, posing significant health and environmental risks due to cadmium content. It requires careful handling under appropriate safety protocols. Its use is strictly regulated and primarily confined to controlled research and specialized industrial material synthesis.
