Overview

Cadmium(2+);silicon(4+);hexafluoride (CAS 17010-21-8) is an inorganic fluorosilicate compound with significant toxicological properties and specialized industrial applications. This chemical compound, with the molecular formula CdF6Si and a molecular weight of 254.49 g/mol, represents a complex ionic structure combining cadmium cations, silicon cations, and fluoride anions. The substance exhibits multiple hazard classifications under the GHS system, including carcinogenicity (Category 2), acute toxicity, and specific target organ toxicity with repeated exposure. Its classification under ADR Class 6.1 reflects its toxic nature, requiring specialized handling and transportation protocols. The compound's hazard profile is primarily driven by the presence of cadmium, a heavy metal known for its bioaccumulation potential and chronic toxicity effects. The fluorosilicate structure enhances its chemical reactivity and contributes to both its acute toxicity profile and environmental impact classifications. Like other cadmium-containing compounds such as cadmium(2+) diiodide, this substance poses significant health risks and requires stringent safety measures during handling and storage. Primary industrial applications include specialized electronics manufacturing, where the compound's unique electrical properties are utilized in semiconductor processes, advanced materials synthesis for research applications, and as a precursor in the production of specialized fluoride-based materials. The compound's precise stoichiometry makes it valuable in applications requiring controlled cadmium and fluoride introduction. Due to its hazardous nature, proper risk assessment, personal protective equipment, and waste management protocols are essential when working with this material. OYSI maintains this specialized compound in our European distribution network for qualified industrial customers with appropriate handling capabilities.
