Hydrogen Peroxide 25% ACS Grade

Product Overview

Hydrogen Peroxide 25% ACS Grade is a colorless, highly oxidizing liquid formulated to meet ACS specifications for laboratory and analytical use. With a typical assay of 25% and stringent impurity controls, the solution provides predictable reactivity for quantitative oxidations, bleaching, and disinfection procedures. The product exhibits a low color (APHA typically around 5) and minimal residue after ignition, supporting reproducible results in sensitive analytical workflows. Its density at 20°C is typically 1.1125 g/mL, and the solution remains soluble in water with a boiling range near 151.2°C. The formulation is prepared to minimize trace metals to reduce interference in chemistries and to maintain purity in ACS-grade applications.

Designed for industrial, laboratory, and environmental settings, this ACS-grade hydrogen peroxide delivers reliable performance in oxidizing reactions, water treatment processes, and analytical reagent applications. The product is stabilized to maintain stability under controlled handling and storage conditions, with careful control of chloride, nitrate, sulfate, and heavy metal content to meet stringent industry standards. It is suitable for use in analytical chemistry where stringent purity and consistent specification adherence are required, while being compatible with HDPE or glass containment to minimize potential material interactions.

Safety Precautions

Handle in a well-ventilated area, away from organic materials and reducing agents. Store in cool, dry conditions in HDPE or glass containers, away from direct sunlight to minimize decomposition. Use appropriate PPE, including chemical resistance gloves and splash goggles, and ensure spill control materials are available. Maintain containment to prevent exposure to vapors and contact with skin or eyes. Follow grade-appropriate handling practices per SDS and regulatory requirements.

Observe exposure limits and emergency procedures outlined in the SDS: in case of contact with skin or eyes, rinse immediately with plenty of water and seek medical attention. If inhaled, move to fresh air and consult medical personnel. In the event of ingestion, rinse mouth and do not induce vomiting; seek medical help. For spills, evacuate personnel, ventilate the area, contain with inert absorbents, and dispose of waste per local regulations. UN 2014 classification indicates oxidizing properties; transport with caution according to applicable regulations.
