Sodium Thiosulfate Pentahydrate (Na2S2O3·5H2O) is a versatile, crystalline chemical compound widely used across food processing, pharmaceutical intermediates, water treatment, and feed additives. As a leading Na2S2O3·5H2O supplier, Shijiazhuang Standard IMP&EXP CO.,LTD. delivers this essential product with 99% minimum purity, meeting stringent USA import standards.
Formulated as clear, odorless white crystals, Na2S2O3·5H2O – often called sodium thiosulphate pentahydrate – plays a critical role in dechlorination processes, acting as a reducing agent in gold extraction, and serving as an antioxidant in food preservation (E539). In the USA market, demand surges from food manufacturers needing reliable preservatives, pharma companies requiring antidotes for cyanide poisoning, and water treatment plants combating chlorine residuals.
Our production leverages advanced crystallization techniques from high-purity sodium sulfite and sulfur dioxide, ensuring batch consistency that competitors struggle to match. With over 20 years in food and feed additives, we've exported millions of tons to USA, Brazil, Australia, and beyond. You get not just a chemical – but a strategic partner cutting your total cost of ownership.
Imagine sourcing sodium thiosulfate pentahydrate crystals that dissolve rapidly (solubility: 70.1g/100ml at 20°C), stable up to 48°C before dehydration, and compliant with FCC, USP, and EP pharmacopeia. This isn't generic bulk chem; it's tailored for your ROI-focused operations.
In food applications, Na2S2S2O3·5H2O prevents oxidation in seafood, bakery products, and beverages, extending shelf life by 20-30%. For pharma, it's the go-to for injectable antidotes. Feed producers use it to neutralize toxins, boosting animal health metrics.
Why does quality matter? Low-grade alternatives lead to 15-20% yield losses in processes like photographic fixing or leaching. Our high-purity Na2S2O3 5H2O guarantees zero heavy metals (<10ppm Pb), pH 6.0-7.5, and iron content <0.001% – specs verified by third-party labs like SGS.
Procuring from us means high-speed delivery: 7-14 days to USA ports via optimized sea routes from Tianjin, slashing shipping costs by 30% vs. fragmented suppliers. OEM/ODM customization? We handle particle size (20-80 mesh) and packaging (25kg bags, 1MT jumbos) to your specs.
Backed by our powerful factory in Shijiazhuang – two fermentation departments scaled for 50,000MT/year – we control the supply chain end-to-end. No middlemen markups. Just pure value for your purchasing decisions.
Technical edge: Density 1.69g/cm³, molecular weight 248.18. Store in cool, dry places to maintain pentahydrate form. Safety: Non-toxic, non-flammable, but wear PPE for dust.

3 Core Pain Points Sourcing Na2S2O3·5H2O for USA Operations
As a purchasing manager, you face relentless pressure for cost control and quality. Here's the reality:
- High Prices: Competitors charge $800-1200/MT due to inefficient China's supply chains – inflating your COGS by 20%.
- Low Quality: Impure batches (<98%) cause process failures, like 10-15% downtime in water dechlorination plants. Heavy metals exceed FDA limits, risking recalls.
- High Shipping Costs: Delayed 30+ day deliveries add $150/MT fees, disrupting your JIT inventory.
- Inconsistent Supply: Geopolitical issues halt exports, forcing expensive spot buys.
- Compliance Headaches: Non-FDA compliant product stalls customs, costing weeks.
- No Customization: One-size-fits-all packaging fails your OEM needs.
Data: 68% of USA buyers report quality issues per ICIS reports. Don't let this erode your ROI.
