Hydrogen Peroxide 5% ACS Grade

Product Overview

Hydrogen Peroxide 5% ACS Grade (Dihydrogen Dioxide; Hydrogen Peroxide Solution) is a colorless, highly reactive oxidizer formulated to meet ACS specifications for reagent-grade applications. This 5% solution provides a reliable balance of reactivity and stability, delivering consistent performance in analytical and laboratory workflows. The product is supplied as a clear, colorless liquid with a slight, bleach-like odor and is fully soluble in water. Typical assay is 5.0% w/w, with a stringent specification window (4.9–5.1%) validated by titration with standardized NaOH, ensuring precise concentration control for reproducible results in titration, oxidation, and cleaning protocols. The ACS Reagent Grade designation indicates compliance with high-purity criteria and traceability to recognized standards.

In addition to analytical reagents use, this ACS 5% solution supports a range of laboratory and industrial tasks such as sample digestion, surface oxidation protocols, and controlled bleaching in textile and paper processing. The solution’s low residue after evaporation (typical 0.01% with a maximum of 0.05%) minimizes carryover in sensitive analyses. With a density near 1.01 g/mL at 25°C and a refractive index of approximately 1.406 at 20°C, the product is well-characterized for integration into calibrated analytical systems and quality control procedures.

Safety Precautions

Handle Hydrogen Peroxide 5% ACS Grade in a well-ventilated area, away from organic materials and reducing agents. Store in HDPE or glass containers, protected from direct sunlight and heat sources to minimize decomposition. Use appropriate PPE, including chemical-resistant gloves and splash-protective eyewear, and ensure spill containment measures are in place to manage accidental releases. Follow standard handling procedures per SDS and ensure compatible materials in contact with the solution to avoid unwanted reactions.

In case of exposure or contact, follow the SDS guidance: for eyes or skin, rinse cautiously with water for several minutes and remove contaminated clothing; seek medical attention if irritation persists. If inhaled, move to fresh air and maintain comfortable breathing. For ingestion, rinse mouth and do not induce vomiting; obtain medical attention promptly. Transport is classified as UN 2014, Hydrogen Peroxide, Class 5.1, Packing Group II, reflecting its oxidizing hazard profile and required packaging standards.

Benefits

✔ ACS Grade Purity – Meets stringent ACS Reagent Grade specifications, ensuring high purity and repeatable analytical performance.
✔ Accurate Titration and QC – Certified assay (4.9–5.1 wt%) with validated test methods supports precise concentration control and method transfer.
✔ Low Impurity Profile – Trace metals and anions are tightly controlled (e.g., Fe, Cu, Ni, Zn, Cl⁻, NO₃⁻) to minimize interference in analytical procedures.
✔ Stability and Traceability – Controlled storage and handling guidelines prevent premature decomposition; compliant with ACS and USP-NF monographs for reliability across batches.
