General description

The product is a 50% solution of hydrogen peroxide in water. Hydrogen peroxide is more commonly being used as a green oxidizing agent. It is a better alternative to other oxidants because it has high active oxygen content and the by-product is water.

Application

Hydrogen peroxide solution may be used as an oxidizing agent in the following reactions:
  • Epoxidation of alkenes in the presence of homogeneous metal catalyst.
  • Oxidative halogenation in the presence of metal catalyst.
  • Oxidation of sulfides to sulfoxides and sulfones in the presence of polymer immobilised catalyst.

Packaging

500 mL in poly bottle
4 L in poly drum

Certificate of Analysis

Certificate of Origin

  1. Which document(s) contains shelf-life or expiration date information for a given product?

    If available for a given product, the recommended re-test date or the expiration date can be found on the Certificate of Analysis.

  2. How do I get lot-specific information or a Certificate of Analysis?

    The lot specific COA document can be found by entering the lot number above under the "Documents" section.

  3. What is the molarity of the 50% Hydrogen peroxide solution, Product 516813?

    This product is a 50% (w/w) solution. We can calculate the molarity by using the density (1.197g/mL) and the molecular weight (34.01g/mol). The molarity can be calculated by the following equation: [(50g H2O2)*(1.197g solution)*(1mol H2O2)*(1000mL)] / [(100g solution)*(1mL solution)*(34.01g H2O2)*(1L) = 17.6M.

  4. Why is Hydrogen peroxide solution, Product 516813, packed in plastic bottles?

    This product is packaged in opaque white HDPE bottles because it is light sensitive and per the chemicals encyclopedia published by the Royal Society of Chemistry, has the tendency to degrade in the presence of metal or rough surfaces.

  5. Does Hydrogen peroxide solution, Product 516813, contain a stabilizer?

    Yes; the exact identity of the stabilizer is considered proprietary. However, it contains tin compounds (stannates) and chelating agents.
