Hydrogen Peroxide Extra Pure
SHORT DESCRIPTION
Hydrogen Peroxide Extra Pure is a clear, colorless liquid widely used as a strong oxidizing agent in laboratory and industrial settings. This high-purity grade ensures minimal contamination, making it ideal for analytical chemistry, disinfection, bleaching, and redox reactions. In research labs, it serves as a reliable reagent for oxidation processes and sterilization. Its extra pure formulation enhances consistency and accuracy in sensitive procedures. Due to its reactive and potentially unstable nature, it should be stored in cool, dark conditions in vented containers and handled with appropriate protective equipment.
USES
Primary Laboratory Uses:
- Oxidizing Agent in Chemical Reactions:
Widely used in redox reactions, including organic synthesis, epoxidation, and hydroxylation processes. - Disinfectant and Sterilization Agent:
Serves as a high-purity antimicrobial for sterilizing laboratory equipment, surfaces, and sometimes tissue culture tools. - Environmental and Analytical Testing:
Used in chemical oxygen demand (COD) tests and as a reagent in colorimetric assays for detecting trace elements or functional groups.
Secondary Laboratory Uses:
- Bleaching and Stain Removal in Sample Prep:
Applied to bleach organic material in biological specimens or to remove stains during microscopic slide preparation. - Oxygen Source in Controlled Decomposition Reactions:
Decomposes to release oxygen gas, useful for oxidative degradation studies or oxygen-limited reaction environments. - Component in Fenton’s Reagent:
Combined with iron salts to produce hydroxyl radicals for advanced oxidation processes in environmental chemistry.

FIRST AID MEASURES
Inhalation:
- Move to fresh air immediately.
- Seek medical attention if symptoms like coughing or shortness of breath persist.
Skin Contact:
- Rinse with plenty of water for at least 15 minutes.
- Remove contaminated clothing.
- Seek medical advice if irritation or whitening of skin occurs.
Eye Contact:
- Rinse cautiously with water for several minutes.
- Remove contact lenses if present and easy to do.
- Continue rinsing and get immediate medical attention.
Ingestion:
- Rinse mouth thoroughly with water.

- Do not use combustible extinguishing agents like dry sawdust.
Hazardous Combustion Products:
- Oxygen gas, steam, and potentially explosive vapors in confined spaces.
Firefighter Protection:
- Wear self-contained breathing apparatus (SCBA) and full protective gear.
Approach with caution—containers may rupture under fire conditions.
