High-purity industrial raw materials manufactured with strict Quality Control standards
An in-depth technical analysis of chemical safety compliance, market trends, and supply chain strategies
Sodium Sulfite Anhydrous (CAS Number: 7757-83-7) is a widely used reducing agent. While non-hazardous under standard GHS transport rules, exposure to moisture or high acid levels can release toxic Sulfur Dioxide ($SO_2$) gas. A precise MSDS is critical for plant handlers. It details Section 8 exposure controls, respirators, and Section 10 chemical reactivity protocols.
Industrial consumption is rising across water treatment, photography, mining, and pulp bleaching. Standard specifications mandate ≥96.0% or ≥98.0% purity. In paper and pulp, it acts as a sulfonating agent. In oil drilling and water treatment, it functions as an oxygen scavenger to prevent pipe oxidation and scaling.
Our Sodium Sulfite Anhydrous features a crystalline white powder structure with low trace heavy metals. We guarantee free-flowing properties with customized moisture-proof double-layer PP/PE packaging, preventing oxidation during sea transit. We provide transparent chemical assay data for each shipment.
Safety Information Insight (MSDS Section 10): Keep away from strong acids and oxidizing agents. On contact with acids, it decomposes to release highly choking sulfur dioxide. Store in a cool, dry place. Ensure bags are hermetically sealed, as moisture exposure will convert the active Sodium Sulfite ($Na_2SO_3$) into Sodium Sulfate ($Na_2SO_4$), diminishing its performance as an active reducing agent.
