· JVASP-9335· MgFe4S8

MgFe4S8 is an iron-magnesium sulfide compound that belongs to the thiospinel family of mixed-metal sulfides. This is primarily a research and experimental material studied for its potential in energy storage, magnetic, and catalytic applications rather than an established engineering material with widespread industrial use. The compound's mixed-valence iron sites and magnesium incorporation make it of particular interest in battery chemistry and heterogeneous catalysis research communities exploring alternatives to conventional oxide-based systems.

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.
