· H2 C2 O4 Na2

Sodium oxalate (Na₂C₂O₄) is an inorganic salt compound classified as a ceramic material, consisting of sodium cations bonded to oxalate anions in a crystalline structure. This material is primarily used in analytical chemistry, metallurgical processes, and specialized industrial applications where its chemical properties—particularly its ability to precipitate and chelate metal ions—provide functional value. Engineers select sodium oxalate for laboratory scale-up and process development rather than as a structural material, leveraging its role in metal recovery, ore processing, and quality control testing.

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.
