Sodium Sulfite ACS is a crystalline or powdery substance that appears white in color. Comprised of sodium ions (Na+) and sulfite ions (SO3^2-), sodium sulfite is an inorganic salt that readily dissolves in water. It is commonly employed as a reducing agent and finds extensive use in various industries. Functioning as an inorganic sodium salt with sulfite as its counterion, sodium sulfite ACS is represented by the chemical formula Na2SO3. It is suitable for laboratory purposes.

ChemieR provides an extensive selection of high-purity salts, acids, base and high purity solvents, including alkali metals, alkaline earth compounds, perchlorates, heavy metals, rare earths, transition metals, silver and precious metals, and triflates. ChemieR specialize in inorganic chemicals, offering materials with low moisture content and minimal trace metals. ChemieR stands out with a diverse range of laboratory chemicals, from organic and inorganic reagents to solvents.

Application :

  • Sodium sulfite ACS is also used for sulfonation and sulfomethylation reactions.
  • It can be used as a reducing agent in the hydroxylation of arylboronic acids and arylboronic esters into corresponding phenols, in the transformation of α-amino alcohol methanesulfonate hydrochlorides to sodium α-amino alkanesulfonates and as a SO2 precursor in the multigram synthesis of DABCO·(SO2)2 abbreviated as DABSO.
  • As an oxygen and free chlorine scavenger, it is employed in the water treatment process. It is also used in the production of sodium thiosulfate, detergents, and dyes.
  • Sodium sulfite ACS participates in the purification and isolation of aldehydes and ketones by forming adducts with them.

Benefits :

  • Meet the toughest regulatory standards for quality and purity
  • As an antioxidant
  • As a reducing agent
  • Versatile and effective product
