· Na2 Cr7 O14

Sodium dichromate (Na₂Cr₇O₁₄) is an inorganic chromium compound and strong oxidizing agent that exists as a yellow-orange crystalline solid at room temperature. It is primarily used in industrial chemistry, metal surface treatment, and analytical applications rather than as a structural or functional engineering material itself. The compound serves as a precursor in chromium plating processes, corrosion inhibitor formulations, leather tanning, and laboratory oxidation reactions, though its use has declined in some regions due to environmental and health regulations regarding hexavalent chromium exposure.

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.
