H2O2 Physical & Chemical Properties

Hydrogen Peroxide (H2O2) Solution Properties  (CAS 7722-84-1)

 

Standard Grade hydrogen peroxide is formulated with an inorganic tin-based stabilizer system for high stability and long-term storage.

The 70% concentration can be diluted to 27%, 35% or 50% concentration with most ordinary tap water found in North America. This permits a customer to achieve maximum economy by purchasing hydrogen peroxide at 70% concentration and diluting it to 27%, 35% or 50% for storage. This hydrogen peroxide product is suitable for storage at 70% concentration if desired. Product diluted and drummed at terminal locations meets the stringent assay and stability specifications below.

Standard Grade Hydrogen Peroxide is used extensively for pulp, textile, and environmental applications. It is the most suitable grade available for industrial purposes and should be used whenever possible.

H2O2 has a molecular weight of 34.02 and is nonflammable at any concentration.
