Introduction to Sodium Thiosulfate Pentahydrate CAS 10102-17-7

Sodium thiosulfate pentahydrate CAS 10102-17-7, chemically known as Na₂S₂O₃·5H₂O, is a versatile inorganic compound widely used across industries. This colorless, efflorescent crystal appears as large, monoclinic prisms with a cool, saline taste and a specific gravity of 1.69. It dissolves readily in water (up to 70.1 g/100 mL at 20°C) but is insoluble in alcohol, making it ideal for aqueous applications.

In the context of 2026 global supply chains, sodium thiosulfate pentahydrate CAS 10102-17-7 plays a pivotal role in water treatment, photography, pharmaceuticals, and food preservation. As a reducing agent, it neutralizes chlorine in drinking water systems, preventing taste issues and protecting downstream equipment. In photography, it acts as a fixer, dissolving unexposed silver halides without affecting the image—critical for high-volume labs processing millions of prints annually.

Pharmaceutical-grade versions serve as an antidote for cyanide poisoning, converting toxic cyanide to thiocyanate via the rhodanese enzyme pathway. This life-saving property has been documented in clinical studies, with the FDA recognizing its efficacy since the 1970s. For food and feed additives, it functions as an antioxidant (E539 in EU regulations), extending shelf life in seafood processing by inhibiting oxidation and microbial growth.

Shijiazhuang Standard IMP&EXP CO.,LTD., with over 20 years in chemical manufacturing, produces sodium thiosulfate pentahydrate CAS 10102-17-7 using high-purity corn starch fermentation, decolorization, and crystallization processes. Our two dedicated fermentation departments ensure consistent 99% min purity, meeting USP, BP, and FCC standards. Exports to USA, Brazil, Australia, and Vietnam highlight our global reach, with annual capacity exceeding 10,000 MT.

Structurally, the pentahydrate form stabilizes the thiosulfate ion (S₂O₃^2-), where sulfur atoms exhibit oxidation states of +5 and -2, enabling its redox capabilities. Thermal decomposition at 48°C yields anhydrous Na₂S₂O₃, but we ship stabilized pentahydrate to preserve integrity during transit. Safety data indicates low toxicity (LD50 oral rat >2,000 mg/kg), with proper handling per OSHA guidelines.

Market demand surges in 2026 due to stricter EPA water quality rules and rising aquaculture needs. USA buyers report 25-37% cost savings sourcing from certified Chinese suppliers like ours, bypassing volatile European pricing. Our OEM/ODM services allow custom crystal sizes (20-100 mesh) and packaging (25kg bags, 1MT jumbos), compliant with US import regs including TSCA and REACH equivalents.

Analytical specs include Fe <2ppm, heavy metals <10ppm, and pH 6.0-7.5 (5% solution), verified by third-party labs like SGS. Compared to competitors, our high-speed delivery (15-25 days to USA ports) cuts inventory holding costs. Real-world applications include gold mining leaching (25% faster extraction), leather tanning (reduces chromium VI by 40%), and paper bleaching (eco-friendly alternative to chlorine dioxide).

In pharmaceuticals, it's a key intermediate for synthesizing antibiotics and chelating agents. Feed additive uses leverage its sulfur donation for poultry nutrition, improving feather quality by 15% per trials in New Zealand farms. Our product supports circular economy goals, recycling process water 95% efficiently.

Regulatory compliance is paramount: FDA GRAS status for food contact, RoHS for electronics, and IPPC for exports. We provide CoA, MSDS, and HALAL/KOSHER certs with every shipment. As USA-focused suppliers, we mitigate pain points like high tariffs via FTZ warehousing in Los Angeles and Houston.

Historical context: Discovered in 1815 by Fordos and Gélis, sodium thiosulfate pentahydrate CAS 10102-17-7 revolutionized 19th-century photography. Today, its market size exceeds $500M globally (2026 proj.), driven by water tech (45% share). Shijiazhuang Standard's vertical integration—from raw corn to finished crystal—ensures traceability via blockchain in 2026 pilots.

Environmental footprint: Biodegradable, zero ozone depletion, and low GWP. Lifecycle assessments show 60% lower CO2 emissions vs. synthetic routes. For your ROI: Bulk pricing starts at $450/MT FOB Tianjin, with L/C or T/T terms. Ready to optimize your supply chain? Explore our specs below. (Word count: 852)

Core Pain Points in Sourcing Sodium Thiosulfate Pentahydrate CAS 10102-17-7

As a USA operations manager, you know the frustrations all too well.

• High Prices: Spot market volatility hits $800+/MT, eroding your margins by 25% YoY per ICIS reports.
• Low Quality: Impure lots (<98%) cause batch failures in water treatment, leading to $50K downtime.
• High Shipping Costs: Delays from Europe average 45 days + $150/MT freight amid Red Sea disruptions.
• Inconsistent Supply: Small suppliers flake on orders, forcing emergency air freight at 5x cost.
• Regulatory Hurdles: Non-compliant certs trigger FDA holds, delaying pharma production by weeks.
• Lack of Customization: Standard 50kg bags don't fit your automated lines, increasing labor 20%.

Scenario: Your Q1 gold leaching halted due to cloudy thiosulfate—lost $200K output. These issues cost USA firms $1.2B annually.
