· Nb4 Br12 O4

Nb₄Br₁₂O₄ is a mixed-valence niobium bromide oxide compound belonging to the family of layered halide-based semiconductors. This is primarily a research material studied for its electronic and optical properties rather than a mature commercial compound; niobium halide oxides are of interest in the semiconductor community for potential applications in low-dimensional electronics and photonics due to their tunable bandgap and layered crystal structure.

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.
