Cu2As4S3Cl2
metal· JVASP-29495· Cu2As4S3Cl2
Cu2As4S3Cl2 is a rare mixed-valence copper arsenosulfide chloride compound that exists primarily in research and specialized materials contexts rather than conventional engineering applications. This material belongs to the family of complex metal chalcogenides and represents an experimental composition combining copper, arsenic, sulfur, and chlorine—a combination with limited industrial precedent. The compound's potential lies in semiconductor research, advanced materials chemistry, and possibly specialized optical or electronic applications, though practical engineering use cases remain underdeveloped and would require validation of stability, toxicity, and manufacturing feasibility.
