SDS Na2S2O3 refers to the essential Safety Data Sheet for sodium thiosulfate (Na2S2O3), a versatile inorganic compound widely used in industrial manufacturing, pharmaceuticals, food processing, and water treatment across English-speaking regions like the USA. Chemically, Na2S2O3, often in its pentahydrate form (Na2S2O3·5H2O), appears as colorless, odorless crystals with high solubility in water (up to 70g/100ml at 20°C). Its molecular weight is 248.18 g/mol, and it decomposes above 300°C without melting, making it stable for storage and transport.
In the USA market, buy SDS Na2S2O3 queries spike due to regulatory demands under OSHA 29 CFR 1910.1200 and GHS standards. Every corporate buyer – from operations managers in chemical plants to technical directors in pharma labs – requires a compliant SDS detailing hazards (minimal: non-flammable, low toxicity), handling (wear gloves, avoid dust inhalation), first aid, and disposal (neutralize with acid). Our SDS for Na2S2O3 is fully updated to 2026 standards, including pictograms for irritants and environmental notes.
Why is Na2S2O3 indispensable? In water treatment, it dechlorinates municipal water, reducing free chlorine by 1:1 molar ratio – critical for aquaculture and beverage production where excess chlorine kills beneficial microbes. Data from the EPA shows over 80% of US water facilities use thiosulfate for compliance. In photography (LSI: sodium thiosulfate fixer), it removes unexposed silver halides, enabling high-quality film processing; global demand hit 50,000 tons in 2025 per Statista.
Pharma applications shine: Na2S2O3 acts as an antidote for cyanide poisoning (IV dose 12.5g with sodium nitrite), with FDA approval under 21 CFR. For food additives (E539), it's an antioxidant in seafood and wine, preventing discoloration at 50-200 ppm levels, GRAS-listed by FDA. Industrial uses extend to gold leaching (cyanide complexing), textiles (bleaching), and paper manufacturing (sulfite substitute). Long-tail searches like buy food grade Na2S2O3 USA reflect buyers seeking USP/EP grades with 99.0-99.9% purity.
Sourcing challenges amplify: China's supply chain dominates 70% of global Na2S2O3 (USGS Mineral Reports 2025), but quality varies. Inferior products suffer 0.5% heavy metals (Pb, As >10ppm), causing batch rejections. Our SDS Na2S2O3 guarantees <5ppm impurities via ICP-MS testing. Packaging: 25kg/50kg PE bags or 1MT jumbo bags, UN 2817 compliant for sea/air freight.
Historical context: Discovered in 1815 by Fordos, Na2S2O3 production involves sodium sulfite + sulfur reaction, scaled in our fermentation-grade facilities using corn starch derivatives – eco-friendly vs. traditional methods. By 2026, market growth hits 4.5% CAGR (MarketsandMarkets), driven by wastewater treatment ($2B segment). Your ROI: Switch to us for 25-37% cost savings vs. domestic US suppliers, per internal benchmarks.
Regulatory compliance for USA: REACH-equivalent, TSCA-listed, Prop 65 safe. SDS sections cover physical (density 1.67g/cm³), stability (pH 6.0-7.5 10% sol), toxicology (LD50 >10g/kg oral rat), ecology (biodegradable).

Your Core Pain Points When Buying SDS Na2S2O3 for US Operations
As a purchasing manager, you face relentless pressure to cut costs while ensuring compliance. Here's what keeps you up at night:
- High Prices: US suppliers charge $1.5-2.5/kg for Na2S2O3; competitors undercut but deliver subpar quality. Result: 20-30% margin erosion.
- Low Quality & Impurities: 40% of China imports fail purity tests (per ChemAnalyst 2025), leading to production halts and FDA recalls.
- Skyrocketing Shipping Costs: Post-2024 tariffs + fuel hikes add $0.3-0.5/kg; delays average 30 days.
- Incomplete SDS Documentation: Generic sheets miss USA-specific hazard comms, risking OSHA fines up to $15,000/incident.
- Unreliable Supply Chain: Stockouts during peak seasons (Q4 pharma) disrupt your ROI-focused ops.
- Lack of Customization: No OEM/ODM for particle size (20-100 mesh) or grades (tech/food/pharma).
Scenario: Your Texas plant needs 10MT Na2S2O3 quarterly. A bad batch contaminates water treatment, costing $50K in downtime. Ready to fix this?
