Description

Hydrogen peroxide(Lab and commercial) chemical suppliers in Tamilnadu, Coimbatore, Shree Vissnu scientific company. Hydrogen peroxide is a chemical compound with the formula H2O2. In its pure form, it is a pale blue, clear liquid, slightly more viscous than water. Hydrogen peroxide is the simplest peroxide (a compound with an oxygen–oxygen single bond). It is used as an oxidizer, bleaching agent and antiseptic. Concentrated hydrogen peroxide, or "high-test peroxide", is a reactive oxygen species and has been used as a propellant in rocketry.[5] Its chemistry is dominated by the nature of its unstable peroxide bond. Hydrogen peroxide is unstable and slowly decomposes in the presence of light. Because of its instability, hydrogen peroxide is typically stored with a stabilizer in a weakly acidic solution. Hydrogen peroxide is found in biological systems including the human body. Enzymes that use or decompose hydrogen peroxide are classified as peroxidases.Hydrogen peroxide Structural formula of hydrogen peroxide space filling model of the hydrogen peroxide molecule Names IUPAC name Hydrogen peroxide Other names Dioxidane Oxidanyl Perhydroxic acid 0-hydroxyol Dihydrogen dioxide Oxygenated water Identifiers CAS Number 7722-84-1 ☑ 3D model (JSmol) Interactive image ChEBI CHEBI:16240 ☑ ChEMBL ChEMBL71595 ☑ ChemSpider 763 ☑ ECHA InfoCard 100.028.878 EC Number 231-765-0 IUPHAR/BPS 2448 KEGG D00008 ☑ PubChem CID 784 RTECS number MX0900000 (>90% soln.)
