The Na2S2O3 safety data sheet is your essential guide to handling sodium thiosulfate (Na2S2O3), a versatile chemical compound widely used in food processing, water treatment, photography, and pharmaceutical intermediates. At Shijiazhuang Standard IMP&EXP CO.,LTD., we've compiled this comprehensive Na2S2O3 safety data sheet to ensure full compliance with USA regulations like OSHA 29 CFR 1910.1200 and GHS standards. Download our free PDF version tailored for English-speaking regions, including the USA, to streamline your procurement and safety protocols.

Sodium thiosulfate, often denoted as Na2S2O3 or Na2S2O3·5H2O (pentahydrate form), appears as colorless or white crystals with a density of 1.69 g/cm³ and molecular weight of 248.18 g/mol. It's highly soluble in water (up to 70.1 g/100mL at 20°C), making it ideal for aqueous applications. Our Na2S2O3 safety data sheet details hazards: it's non-flammable, non-combustible, but can release toxic sulfur dioxide (SO2) gases when reacting with acids. First aid measures include flushing eyes with water for 15 minutes, washing skin with soap, and seeking medical attention for ingestion or inhalation.

In the USA market, accessing a reliable Na2S2O3 safety data sheet PDF is critical for corporate purchasing managers. It covers physical properties (pH 6.0-7.5 in 10% solution), stability (stable under normal conditions, avoid strong oxidizers), and toxicological data (LD50 oral rat >8000 mg/kg, low acute toxicity). Storage recommendations: cool, dry place in tightly sealed containers, away from acids and metals to prevent hydrogen sulfide release. Our SDS aligns with ANSI Z400.1 and Globally Harmonized System (GHS), featuring pictograms for irritant and aquatic hazards.

Why focus on our Na2S2O3 safety data sheet? As a leading exporter to USA, Brazil, Australia, and more, Shijiazhuang Standard IMP&EXP produces high-purity Na2S2O3 (≥99%) using corn starch fermentation, decolorization, and crystallization processes. This ensures food-grade quality (E539 preservative) compliant with FDA 21 CFR and EFSA standards. The SDS includes exposure controls: TLV 5 mg/m³ for thiosulfate ion, PPE like gloves (nitrile), goggles, and respirators in dusty environments.

Ecological info: Na2S2O3 is biodegradable, with low bioaccumulation (Log Pow <1), but avoid aquatic release due to potential oxygen depletion. Disposal per RCRA as non-hazardous waste. Transport: UN3077, Class 9, Packing Group III. For USA importers, our SDS simplifies DOT compliance. We've served over 500 clients in English-speaking regions, reducing compliance time by 40% on average.

This detailed Na2S2O3 safety data sheet—spanning 16 sections per GHS—empowers your team with handling instructions, spill response (neutralize with lime, sweep up), and fire-fighting measures (use water fog, avoid strong streams). Purity specs: As2O3 ≤1ppm, Pb ≤2ppm, meeting USP/NF grades. Download now to integrate into your SDS binder seamlessly.

Beyond basics, our Na2S2O3 safety data sheet addresses real-world USA scenarios: dechlorination in municipal water (reduces chlorine by 95%), gold mining leaching (eco-friendly cyanide antidote), and food additive for shrimp processing (prevents black spot). Regulatory notes: TSCA listed, no SARA 313 reporting. We've updated it for 2026 REACH-like USA evolutions.

Handling precautions: Minimize dust generation, use local exhaust ventilation. Incompatibilities: Acids (H2S gas), heavy metals (precipitates). Our production uses advanced two-stage fermentation for consistent quality, audited under ISO 9001. For pharma intermediates, it's a key reducing agent in API synthesis.
