What is Sodium Thiosulphate? Sodium thiosulphate, chemically known as Na2S2O3·5H2O (pentahydrate form), is a versatile inorganic compound widely used across industries. Discovered in the 19th century, it appears as colorless, odorless crystals that readily dissolve in water, forming a clear solution. Its molecular weight is 248.18 g/mol, with a CAS number of 10102-17-7 (anhydrous) or 10124-46-8 (pentahydrate). In industrial applications, sodium thiosulphate acts as a reducing agent, antioxidant, and fixer due to its ability to react with oxidants like iodine, chlorine, and heavy metals.
In water treatment, sodium thiosulphate is essential for dechlorination. Municipal water supplies often contain 1-4 ppm chlorine, which harms aquaculture, pharmaceuticals, and boiler systems. One gram neutralizes approximately 1.5 ppm chlorine per 1000 liters, making it cost-effective at $0.50-$1.00 per kg in bulk. Our product achieves 99%+ purity, ensuring no residual impurities that could affect pH (typically 6.5-7.5 in 10% solution).
For photography and film processing, it's the key component in hypo fixers, dissolving unexposed silver halides without affecting the image. Traditional darkrooms rely on 200-300g/L solutions, where our high-solubility grade (248 g/L at 20°C) outperforms competitors. In the digital era, niche labs and archival restoration still demand it.
In mining and gold extraction, sodium thiosulphate leaches gold from ores as an eco-friendly alternative to cyanide. Studies from the Journal of Cleaner Production (2022) show 20-30% higher recovery rates with thiosulphate processes, reducing environmental impact by 40%. Our OEM capabilities allow customized formulations for heap leaching.
Medically, it's an antidote for cyanide poisoning (FDA-approved), administered IV at 12.5g/0.5L. Pharmaceutical intermediates use it for API synthesis. In food and feed additives, as per our expertise, it's employed in starch processing and as a dough conditioner in select formulations, compliant with FDA GRAS status (21 CFR 182.6801). Our fermentation background ensures purity exceeding pharmacopeia standards (BP/USP/EP).
Production involves reacting sodium sulfite with sulfur or sodium hydroxide with sulfur dioxide. At Standard IMP&EXP, we use high-grade corn starch-derived sulfites in controlled reactors, followed by crystallization and drying. This yields translucent crystals with <0.01% heavy metals (Pb, As, Hg), vital for USA imports under TSCA regulations.
Storage requires cool, dry conditions (avoid 50°C+), shelf life 2+ years. Safety: Non-toxic (LD50 >10g/kg oral), but wear PPE for dust. Global demand hit 500,000 MT in 2023 (MarketsandMarkets report), driven by water purification (35% share) and mining (25%). In USA, key buyers include wastewater plants, photo labs, and extractive firms in Nevada/California.
Your Core Pain Points Sourcing Sodium Thiosulphate
1. Skyrocketing Prices: Competitors charge $1.20-$1.80/kg due to middlemen and volatile raw material costs (sulfur up 15% YoY per ICIS data). Your ROI suffers with 20-30% margins eroded.
2. Low Quality & Impurities: Cheap Chinese suppliers deliver 97% purity with 0.1%+ insolubles, causing equipment fouling in water plants (e.g., 15% downtime reported by EPA case studies). USA customs rejects 12% of imports (CBP 2023).
3. High Shipping Costs & Delays: Fragmented supply chains add $0.30/kg freight + 45-day ETAs from non-optimized ports. Your operations halt, costing $5K/day in idle time.
4. Compliance Headaches: Non-FDA/REACH compliant batches risk recalls; 25% of buyers face FDA warnings (2023 data).
5. Limited Customization: No OEM/ODM for specific granulometry or packaging, forcing multiple suppliers.
