Hydrogen Peroxide 25% ACS Grade

Product Overview

Hydrogen Peroxide 25% ACS Grade is a high-purity aqueous solution of hydrogen peroxide, formulated to meet the strict analytical standards of the American Chemical Society. This chemical intermediate, represented by the molecular formula H2O2, has a molecular weight of 34.015 and a CAS registry number of 7722-84-1. As a premier distributor based in Texas, Alliance Chemical provides this high-quality oxidizer for facilities requiring rigorous quality controls. Check our selection of industrial bases for other high-purity chemical offerings. This specific concentration balances oxidative power with stability, providing an essential reagent for diverse laboratory, manufacturing, and industrial workflows.

This colorless liquid exhibits unique chemical properties, acting primarily as a strong oxidizing agent in controlled environments. With a density of 1.11 at 68 °F, this aqueous solution is denser than water and will sink in unstirred systems. Our formulation is processed to minimize trace impurities, ensuring that your chemical manufacturing processes remain consistent from batch to batch. We supply this solution in multiple packaging configurations, ranging from 1-quart bottles to bulk quantities, catering to both research laboratories and large-scale industrial plants.

Why This Grade

Selecting ACS Grade ensures that the impurity tolerances are strictly defined and verified, preventing unexpected reaction variations. For many chemical processes, using a lower technical grade introduces metal ions like iron or copper, which act as catalysts for the rapid, uncontrolled decomposition of H2O2. This 25% concentration is specifically chosen over higher concentrations because it offers a safer handling profile while maintaining sufficient oxidizing strength for synthesis, bleaching, and chemical modification.

Using the incorrect grade or concentration can lead to significant failure modes in industrial operations. High level trace contaminants in non-ACS grades can poison sensitive catalysts, ruin expensive batches of chemical products, or cause dangerous pressure buildup in storage vessels due to accelerated decomposition. For processes engineered specifically for a 25% concentration, substituting a higher or lower concentration can alter reaction kinetics, resulting in incomplete reactions or excessive heat generation.

Industrial Applications

• Chemical Synthesis — Used as a highly controlled oxidizing agent in the synthesis of organic and inorganic chemicals, preventing side reactions.
• Textile and Pulp Bleaching — Employed in the bleaching of wood pulp and textiles to achieve high brightness without damaging the structural fibers.
• Surface Treatment and Etching — Utilized in the semiconductor and electronics industries for precision surface etching and cleaning of silicon wafers.
• Wastewater Treatment — Acts as an oxidizing agent to neutralize sulfur compounds and reduce chemical oxygen demand in industrial effluent streams.
• Laboratory Analysis — Serves as an analytical reagent in laboratory research and quality control testing where high-purity standards are mandatory.

Hazmat & Shipping

Hydrogen Peroxide 25% ACS Grade is a regulated hazardous material. The proper shipping name is Hydrogen peroxide, aqueous solution, with not less than 20 percent but not more than 60 percent hydrogen peroxide. It is classified under UN2014 as Hazard Class 5.1 (Oxidizer), with subsidiary hazard properties (Corrosive), and is assigned to Packing Group II. The GHS Signal Word is Danger. Due to its oxidizing nature, it can accelerate the combustion of other materials and must be shipped in accordance with strict DOT regulations.

Personnel handling this material must wear appropriate Personal Protective Equipment (PPE) aligned with the GHS Hazard Statements H271, H302, H314, and H332. Specifically, handlers must wear chemical-resistant gloves, protective clothing, and eye or face protection, as indicated by GHS Precautionary Statements like P280 and P283. Because this solution causes severe skin burns and eye damage, emergency eyewash stations and safety showers must be accessible in handling areas. Alliance Chemical ensures all transport conforms to safety standards, and we include a comprehensive Safety Data Sheet (SDS) with every order.

Handling & Storage

Store Hydrogen Peroxide 25% ACS Grade in a cool, dry, well-ventilated area, away from direct sunlight and heat sources, maintaining temperatures ideally below 86 °F. Keep containers tightly closed in their original, vented packaging — hydrogen peroxide can slowly decompose to release oxygen gas, generating pressure. Compatible container materials include high-density polyethylene (HDPE) and certain passivated stainless steels. Avoid contact with incompatible substances such as organic materials, strong reducing agents, heavy metals, strong bases, and combustible materials, which can trigger rapid decomposition.
