· JVASP-30191· MgCl2O

MgCl2O (magnesium chloride oxide) is an inorganic ceramic compound combining magnesium, chlorine, and oxygen into a mixed-anion structure. This material belongs to the family of oxyhalide ceramics, which are relatively uncommon compared to conventional oxides and are primarily explored in research contexts for specialized applications requiring specific combinations of ionic bonding and chemical stability.

Regulatory Screening

Environmental

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.
