Hydrogen Peroxide 12% ACS Grade

Product Overview

Hydrogen Peroxide 12% ACS Grade is a colorless, high-purity oxidizing solution designed for analytical and industrial laboratory applications. The product, formulated as an ACS-grade reagent, delivers consistent performance in titrations, oxidative digestions, and analytical prep workflows. Typical assay is 12 wt%, with a narrow specification window (min 11.7%, max 12.3%) verified by iodometric or standardized thiosulfate titration, ensuring reliable reagent integrity across batches. At 20°C, the solution exhibits a specific gravity near 1.111 and a color alpha maximum around 2 (typical), supporting rapid visual assessment and compatibility with spectroscopic and chromatographic methods. The formulation is tuned to minimize residues after evaporation and to maintain low contaminant levels critical for analytical procedures.

This ACS-grade hydrogen peroxide is stabilized for stability and supplied with ultra-low levels of chloride, nitrate, sulfate, phosphate, and heavy metals to reduce interference in sensitive analyses. The product is suitable for laboratory reagents, oxidizing reactions, and as a bleaching and sanitizing adjunct in controlled environments where precise oxygen delivery is required. All handling and storage considerations align with standard laboratory practices for oxidizers, with clear guidance provided in the accompanying SDS and COA to support compliance with regulatory expectations (ACS Reagent Grade, USP-NF Monograph).

Safety Precautions

Handle with care as a strong oxidizer. Store in a cool, dry place away from direct sunlight, in compatible containers (HDPE or glass). Ensure proper ventilation and use of PPE including chemical-resistant gloves, splash goggles, and a lab coat. Keep away from organic materials and reducing agents to prevent hazardous reactions; follow SDS-based handling procedures and verify container integrity prior to use.

In case of spills or exposure, evacuate unprotected personnel, ventilate the area, and consult the SDS for emergency guidance. For skin or eye contact, rinse thoroughly with water for several minutes and remove contaminated clothing. If inhaled or ingested, seek immediate medical attention and follow first aid instructions in the SDS. Transport and labeling comply with UN 2014 Hydrogen Peroxide, Class 5.1, Packing Group II requirements.
