· Cr4 H4 O8

Cr4H4O8 is a chromium-based oxide compound with semiconductor properties, representing a mixed-valence chromium hydroxide or oxyhydroxide phase. This material belongs to the family of transition metal oxides that exhibit semiconductor behavior, making it of interest in research contexts for catalysis, electrochemical devices, and photocatalytic applications where chromium's variable oxidation states can be leveraged. While not yet widely established in mainstream industrial production, chromium oxide semiconductors are explored for their potential in water treatment, gas sensing, and energy conversion devices where the material's electronic properties and chemical reactivity offer advantages over simpler oxides.

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.
