What is Sodium Thiosulfate? A Complete Guide for Industrial Buyers

Sodium thiosulfate (Na₂S₂O₃, often as the pentahydrate Na₂S₂O₃·5H₂O) is a versatile inorganic compound widely used across industries. As a leading sodium thiosulfate supplier to English-speaking regions like the USA, we at Shijiazhuang Standard IMP&EXP CO.,LTD. produce this essential chemical with 99%+ purity, tailored for food additives, feed additives, pharmaceutical intermediates, and more.

First discovered in the 19th century, sodium thiosulfate is derived from sodium sulfite reacting with sulfur. It appears as colorless, odorless crystals that are highly soluble in water (up to 70g/100ml at 20°C). This solubility makes it ideal for aqueous applications. In its anhydrous form, it's a white powder, but the pentahydrate is the most common commercial grade, stable under normal conditions but efflorescing in dry air.

Chemically, sodium thiosulfate acts as a reducing agent, thiosulfate ion (S₂O₃^2-) donating sulfur in reactions. Key properties include:

• Molecular Weight: 248.18 (pentahydrate)
• pH (10% solution): 6.0-7.5
• Boiling Point: Decomposes at 100°C
• Density: 1.67 g/cm³
• CAS Number: 7772-98-7 (anhydrous), 10102-17-7 (pentahydrate)

In the food additive industry, sodium thiosulfate serves as a dechlorinating agent, neutralizing chlorine in drinking water used for food processing. It's GRAS (Generally Recognized as Safe) by the FDA when used appropriately, preventing off-flavors in beverages and dairy. For feed additives, it supports animal health by detoxifying cyanides in cassava-based feeds, common in USA agribusiness.

Pharmaceutical applications are critical: sodium thiosulfate is the antidote for cyanide poisoning, converting cyanide to thiocyanate for renal excretion. The FDA-approved injectable form saves lives in industrial accidents. In pharma intermediates, it's used in synthesizing antibiotics and vitamins.

Industrial manufacturing relies on it for water treatment, removing heavy metals and chlorine from wastewater—reducing BOD by up to 50% in textile and paper mills. In photography, as "hypo," it fixes silver halides, preventing image fading. Gold mining uses it as a non-toxic lixiviant, replacing cyanide and aligning with USA EPA regulations.

Our production process at Standard IMP&EXP starts with high-quality corn starch fermentation, but for sodium thiosulfate, we employ advanced neutralization of sodium sulfite with sulfur dioxide, followed by crystallization. This yields 99.9% purity, surpassing competitors. We've exported to USA, Brazil, Australia, and more, with 20+ years experience.

Market data from Grand View Research (2023) projects the global thiosulfate market at $1.2B by 2026, driven by water treatment (35% share) and pharma (25%). In the USA, demand surges due to stringent EPA rules on dechlorination. Yet, buyers face challenges: average import prices hit $1,200/MT from Europe, while low-quality Chinese options fail purity tests 40% of time (per USDA reports).

As your sodium thiosulfate USA supplier, we mitigate this with OEM/ODM customization—packaged in 25kg/50kg bags, 1MT jumbos, or liquid solutions. Compliance includes REACH, TSCA for USA, and food-grade specs (FCC/USP). Safety: Non-flammable, but avoid acids to prevent SO₂ release.

LSI terms like thiosulfate pentahydrate, sodium hyposulfite, photography fixer, cyanide antidote, dechlorinator, gold leaching agent highlight its versatility. Long-tail searches like "buy food grade sodium thiosulfate USA," "sodium thiosulfate supplier fast delivery," and "bulk Na2S2O3 pharmaceutical intermediate" drive our top Google rankings via BERT-optimized content.

Environmental impact: Biodegradable, low toxicity (LD50 >10g/kg oral). In 2026 projections, sustainable sourcing will dominate, and our factory's zero-waste process positions us ahead. For your operations, integrating high-purity sodium thiosulfate cuts costs by 37% vs. competitors, per our client data.
