| General description: | Dimethyl selenide is a high-purity (≥99.0% by GC), volatile organoselenium compound in liquid form, primarily used as a catalyst and a precursor for solution and vapor deposition processes. Its excellent volatility and reactivity make it suitable for thin-film fabrication techniques such as chemical vapor deposition (CVD) and atomic layer deposition (ALD), particularly in the synthesis of semiconductor and optoelectronic materials. |
