Hydrogen Peroxide 5% ACS Grade

Product Overview

Hydrogen Peroxide 5% ACS Grade is a high-purity, colorless liquid oxidizer manufactured to meet the rigorous specifications of the American Chemical Society (ACS). Also known as H2O2 or Peroxide, this solution provides a precise 5.0% w/w concentration (range 4.9–5.1%), validated for consistency in sensitive analytical workflows. Unlike technical grades, ACS Reagent Grade ensures strictly controlled impurity limits, making it the preferred choice for laboratory titrations, sample preparation, and quality control applications.

This 5% solution serves as a versatile reagent in industrial and research settings. It is widely used for sample digestion, chemical synthesis, and surface oxidation protocols where residue minimization is critical. With a low residue after evaporation (typical 0.01%) and tight control over trace metals, it ensures reproducible results without contamination. The product is fully soluble in water and features a density of approximately 1.01 g/mL at 25°C.

Safety Precautions

Hydrogen Peroxide 5% is a strong oxidizer and must be handled with care. Store in a cool, well-ventilated area away from direct sunlight, heat, combustible materials, and reducing agents. Keep containers tightly closed and use vented caps if necessary to prevent pressure buildup from decomposition. Operators should wear appropriate Personal Protective Equipment (PPE), including chemical-resistant gloves and safety goggles.

Refer to the Safety Data Sheet (SDS) for detailed safety information. In the event of skin or eye contact, rinse immediately with copious amounts of water. If inhaled, move to fresh air. This product is regulated for transport as an oxidizer (UN 2014, Class 5.1).
