· Mg4 Cl8 O4

Mg₄Cl₈O₄ is an oxyhalide semiconductor compound combining magnesium, chlorine, and oxygen in a layered crystalline structure. This material is primarily of research interest for optoelectronic and photocatalytic applications, as oxyhalides are being explored as alternatives to conventional semiconductors for visible-light absorption and charge separation. While not yet widely commercialized, magnesium oxyhalides represent an emerging class of materials investigated for potential use in photocatalysis, environmental remediation, and solid-state electronic devices where tunability of bandgap and low toxicity are valued.

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.
