Hydrogen Peroxide 12% ACS Grade

Product Overview

Hydrogen Peroxide 12% ACS Grade is a high-purity, colorless oxidizing solution manufactured to meet American Chemical Society (ACS) specifications. Commonly referred to by its formula H2O2 or simply as peroxide in laboratory settings, this reagent is essential for analytical workflows requiring low contaminant levels. The solution maintains a tight assay specification (11.7% to 12.3%) and is stabilized to ensure consistent performance in titrations, oxidative digestions, and inorganic preparations.

This formulation is characterized by ultra-low levels of heavy metals, chlorides, and sulfates, minimizing interference in sensitive instrumentation. It is widely used in chemical manufacturing, semiconductor processing, and laboratory research where trace metal impurities must be strictly controlled. As a strong oxidizer, it effectively supports reaction synthesis and sample preparation. All documentation, including SDS and COA, confirms compliance with ACS Reagent Grade standards.

Safety Precautions

Hydrogen Peroxide 12% is a strong oxidizer and must be handled with appropriate safety protocols. Store in a cool, vented area away from direct sunlight, combustibles, and reducing agents. Personnel should utilize proper Personal Protective Equipment (PPE), including splash goggles, chemical-resistant gloves, and lab coats to prevent skin and eye contact.

Refer to the Safety Data Sheet (SDS) for detailed handling instructions. In the event of exposure, rinse the affected area with copious amounts of water immediately. Ensure adequate ventilation during use. This product is regulated as a hazardous material for transport (UN 2984, Class 5.1).
