Hydrogen Peroxide 5% Technical Grade

Product Overview

Hydrogen Peroxide 5% Technical Grade (synonyms: H2O2 5%, Hydrogen Dioxide 5%) is a colorless, clear liquid with a characteristic sharp odor and strong oxidizing properties. This 5% technical grade solution is formulated for stability and consistent performance in water treatment, pH adjustment, and ancillary industrial processes where controlled oxidation is required. The product is supplied under controlled conditions to minimize decomposition, with tight specifications on assay, color, and trace impurities to support reliable downstream results in process streams and analytical workflows. Typical assay is near 5% w/w with a permitted range of 4.5–5.5% as determined by the potassium permanganate time test (titration with standardized KMnO4).

In addition to its primary oxidizing role, this grade is designed for compatibility with moderate-use bleaching, disinfection, and chemical synthesis steps where material compatibility and predictable concentration stability are paramount. The solution is soluble in water, with a near-neutral density and low organic impurity profile, enabling straightforward integration into aqueous systems without significant phase separation or odor issues. Storage in appropriate HDPE or glass containers and proper handling in ventilated environments are essential to preserve efficacy and minimize decomposition risks.

Safety Precautions

Handle and store Hydrogen Peroxide 5% Technical Grade in well-ventilated areas away from direct sunlight and organic materials. Use containers made of HDPE or glass to prevent container-initiated reactions. Keep away from reducing agents and incompatible substances, and ensure containers are properly labeled and closed when not in use. PPE should include chemical-resistant gloves, splash goggles, and protective clothing; appropriate fume management is advised to minimize inhalation exposure. Follow the storage guidelines to prevent disproportionation and maintain product stability during warehousing and distribution.

For spill response and emergency procedures, evacuate the area as needed and follow standard chemical spill clean-up protocols. In case of contact with eyes or skin, rinse immediately with copious water for several minutes and remove contaminated clothing; seek medical attention for exposure incidents. Inhalation of vapors should be mitigated by moving to fresh air; if symptoms persist, seek medical evaluation. Refer to the Safety Data Sheet (SDS) for UN 2014 Hydrogen Peroxide, Class 5.1, Packing Group II guidelines, first-aid measures, and transport recommendations to ensure compliance with OSHA and local regulations.
