· Cl1 Cu1

CuCl (copper(I) chloride) is an inorganic semiconductor compound consisting of copper and chlorine in a 1:1 stoichiometric ratio. This material is primarily investigated for optoelectronic and photonic applications due to its direct bandgap properties, though it remains largely in research and development rather than high-volume industrial production. CuCl is notable for its potential in UV-emitting devices, photon detectors, and quantum dot applications where its semiconductor characteristics could offer advantages over conventional materials, though practical implementation faces challenges related to material stability and processing compared to more established alternatives like GaN or ZnSe.

RoHS, REACH, and Prop 65 statuses are validated against official substance lists (ECHA SVHC Candidate List, OEHHA Prop 65, RoHS Annex II). Other regulations are estimated from composition and material classification. All screening is a starting point for due diligence — always verify with your supplier before making compliance decisions.
