Potassium Thiosulfate (CAS 10294-66-3) is a chemical compound valued for its versatility across industries. Available in distinct forms – a high-purity solid and a concentrated liquid – understanding their specifications is crucial for procurement managers and R&D scientists. As a leading manufacturer and supplier, we provide both forms, ensuring clients can select the optimal product for their specific needs, whether for pharmaceutical synthesis, agricultural applications, or other industrial processes.

Potassium Thiosulfate: Solid (97% Assay)

The solid form of Potassium Thiosulfate typically presents as a white crystalline powder. Its high assay of 97% makes it suitable for applications demanding precise chemical composition and minimal impurities. Key specifications for our solid Potassium Thiosulfate include:

  • Appearance: White crystalline powder
  • Assay (Titration): ≥ 97.0%
  • Loss on Drying: ≤ 0.30% MAX
  • Magnesium (Mg): ≤ 5 ppm MAX
  • Iron (Fe): ≤ 10 ppm MAX

This high-purity solid is ideal for laboratory use, pharmaceutical intermediates where stringent purity is required, and dry blending applications where precise measurement is critical. For businesses looking to buy this form, consistent quality and reliable sourcing are key considerations.

Potassium Thiosulfate: Liquid (50% Solution)

Our liquid Potassium Thiosulfate is a clear, often colorless to light yellow, transparent solution with a specified concentration. Commonly presented as a 50% solution, it offers convenience in handling and application, particularly in liquid-based industrial processes and agricultural fertigation. The typical specifications for our liquid Potassium Thiosulfate are:

  • K₂S₂O₃ Concentration: ≥ 50 g/100g
  • K₂O Content: ≥ 25 g/100g
  • S Content: ≤ 17 g/100g
  • Sulphate (SO₄): ≤ 2 g/100g
  • Density (20°C): ≤ 0.5 kg/l (Note: This density spec seems unusual for a 50% solution, typical density would be higher. This may be a typo in the source data and should be verified.)
  • pH-value (10%): 3.8-4.8
  • Fe Content: ≤ 200 mg/kg

The liquid form is highly valued for its ease of incorporation into irrigation systems for agriculture or for use in industrial processes where liquid handling is preferred. Its solubility and readily available nutrient forms (K₂O and S) make it efficient for plant uptake in agricultural settings.

Choosing the Right Form and Partnering with a Supplier

The choice between solid and liquid Potassium Thiosulfate depends heavily on the application. For pharmaceutical synthesis requiring high purity and dry reactions, the solid form is often preferred. For agricultural fertigation or industrial mixing where liquid systems are in place, the 50% solution offers convenience and efficiency. As a leading manufacturer and supplier, we offer both to cater to the diverse needs of our clientele. When you need to purchase Potassium Thiosulfate, understanding these specifications ensures you acquire the correct product. We provide detailed technical data and competitive price quotations, making us your ideal partner for chemical sourcing from China.
