Original price was: $ 19.00.Current price is: $ 18.54.
Sodium Hydrogen Sulphite Extra Pure is a white to pale yellow crystalline powder with a pungent sulfur dioxide odor. It is a versatile reducing agent widely used in laboratory, industrial, and food applications for its antioxidant, preservative, and dechlorinating properties. In laboratories, it serves as a reagent for redox reactions and oxygen scavenging. It is also used in water treatment for chlorine removal and in food processing as an antimicrobial and antioxidant agent (E221). Due to its ability to release sulfur dioxide gas, careful handling and storage in sealed containers are essential to maintain quality and ensure safety. The Extra Pure grade ensures high purity suitable for analytical, pharmaceutical, and food industry applications.
