· Sn4 I4 Cl4

Sn₄I₄Cl₄ is a mixed-halide tin compound belonging to the family of halide perovskites and perovskite-related semiconductors. This is primarily a research material rather than an established engineering material, investigated for its semiconducting and optoelectronic properties as part of broader efforts to develop lead-free alternatives to conventional halide perovskites. The material's potential lies in photovoltaic devices, light-emitting applications, and radiation detection, where the combination of tin, iodide, and chloride provides tunable bandgap and electronic properties while avoiding the toxicity concerns of lead-based compounds.

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.
