· Sn2

Sn2 is a tin-based semiconductor compound representing a research-phase material within the tin chalcogenide or tin-group IV family. This material is being investigated for potential optoelectronic and photovoltaic applications where tin's lower toxicity compared to lead-based semiconductors offers environmental and regulatory advantages. The material's position in the semiconductor landscape makes it of interest for emerging technologies in thin-film solar cells, photodetectors, and other light-responsive devices where alternative, less toxic semiconductor platforms are needed.

Regulatory Screening

Environmental

Export Control

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.
