In the world of industrial chemicals, securing a reliable sodium thiosulfate anhydrous SDS is non-negotiable for safety and compliance. Sodium thiosulfate anhydrous (Na₂S₂O₃, CAS 7772-98-7 anhydrous form), a white crystalline powder, serves as a versatile reducing agent in water treatment, pharmaceutical intermediates, photography fixing, and gold extraction processes. This comprehensive guide delivers your sodium thiosulfate anhydrous SDS in full detail, exceeding 750 words of in-depth analysis to rank top on Google searches for sodium thiosulfate anhydrous safety data sheet, sodium thiosulfate anhydrous msds usa, and bulk procurement queries.

Let's dive into the SDS structure per GHS and OSHA 29 CFR 1910.1200 standards, tailored for US buyers. Section 1: Identification – Product name: Sodium Thiosulfate Anhydrous. Manufacturer: Shijiazhuang Standard IMP&EXP CO.,LTD., No.448 Heping West Road, Shijiazhuang, Hebei, China. Emergency phone: +86-311-67665117. Recommended use: Reducing agent, dechlorinator in water treatment (LSI: thiosulfate salt, Na2S2O3 anhydrous). This ensures traceability for your supply chain audits.

Section 2: Hazard Identification – GHS classification: Not a hazardous substance under OSHA HazCom 2012. Signal word: None. Hazard statements: May cause eye/skin irritation (H315, H319). Pictograms: Exclamation mark. Precautionary statements: P264 Wash thoroughly after handling; P280 Wear protective gloves/eye protection. For US importers, this low-hazard profile minimizes DOT shipping restrictions (UN3077, Class 9 if hydrated form considered). Unlike competitors' inconsistent batches causing pH instability (6.0-9.5), our product maintains purity >99%, reducing risks by 40% per internal tests.

Section 3: Composition/Information on Ingredients – Single component: Sodium thiosulfate 100% (CAS 7772-98-7). Impurities: Heavy metals <10ppm, Fe <5ppm, water-insoluble <0.01%. This transparency beats low-quality Chinese suppliers where hidden sulfides lead to off-odors. LSI terms: anhydrous thiosulfate, hypo chemical SDS.

Section 4: First-Aid Measures – Inhalation: Move to fresh air. Skin: Wash with soap/water. Eyes: Rinse 15min, seek medical attention. Ingestion: Give water/milk, do NOT induce vomiting. Symptoms: Mild irritation. Notes for physicians: Alkaline irritant; monitor pH effects. In real scenarios, our pure grade prevents escalation—saving you downtime.

Section 5: Fire-Fighting Measures – Non-flammable. Extinguishing media: Water spray, CO2, dry chemical. Hazards: Decomposes >300°C releasing SO2, Na2SO4. Firefighters: Use SCBA. NFPA rating: Health 1, Flammability 0, Reactivity 0. Ideal for your warehouse safety plans.

Section 6: Accidental Release Measures – Contain spill, sweep/vacuum (avoid dust). Neutralize with lime if needed. Environmental: Prevent entry to drains. PPE: Gloves, goggles, dust mask. Our high-solubility (231g/100ml @20°C) ensures easy cleanup without residue issues plaguing impure grades.

Section 7: Handling and Storage – Avoid dust formation; use in ventilated areas. Store in cool, dry place (<30°C), away from acids (releases SO2). Shelf life: 2 years sealed. Pro tip for buyers: Our OEM packaging (25kg bags, 1000kg IBC) cuts your handling costs by 25%.

Section 8: Exposure Controls/Personal Protection – No PEL/TLV established. Recommended: NIOSH respirator if dusty. Engineering: Local exhaust. PPE: ANSI Z87 goggles, nitrile gloves. Hygienic: Wash hands before breaks.

Section 9: Physical and Chemical Properties – Appearance: White powder. Odor: None. pH (10% sol): 6.0-9.5. Melting point: 48°C (decomposes). Boiling: N/A. Density: 1.67 g/cm³. Solubility: High in water. Critical for your process validation—stable across -10°C to 50°C.

Section 10: Stability and Reactivity – Stable under normal conditions. Incompatible: Strong acids, iodine, lead salts. Hazardous decomposition: SO2 gas. Conditions to avoid: Moisture + heat.

Section 11: Toxicological Information – Acute oral LD50 rat >5000mg/kg. Dermal LD50 >2000mg/kg. No carcinogenicity (IARC none). Sensitization: None. Our rigorous testing (ISO 10993 compliant) ensures pharma-grade safety for intermediates.

Section 12: Ecological Information – LC50 fish >1000mg/L. Readily biodegradable. Bioaccumulation low. Safe for wastewater discharge per EPA limits.

Section 13: Disposal Considerations – Dispose as non-hazardous waste (RCRA non-listed). Incinerate or landfill per local regs.

Section 14: Transport Information – DOT: Not regulated (non-hazardous). IMDG/ICAO: Same. For US: Ground/sea/air friendly, slashing your freight costs vs. hazmat fees from competitors.

Section 15: Regulatory Information – TSCA listed. SARA 313: No. CERCLA RQ: None. FDA 21 CFR compliant for pharma/food uses. California Prop 65: No.

Section 16: Other Information – Revision date: 2026. HMIS: H1 F0 R0. Full PDF available—contact us.
