Sodium bisulfite, mixture of NaHSO3 and Na2S2O5 (CAS 7631-90-5)
QUICK LINKS
Sodium bisulfite, a mixture of sodium bisulfite (NaHSO3) and sodium metabisulfite (Na2S2O5), is widely recognized for its reducing and antioxidant properties, making it a valuable chemical in various scientific applications. It is extensively used in organic synthesis for the selective reduction of aldehydes and ketones to alcohols, and in biochemical processes to prevent oxidation that could degrade sensitive compounds. One of its key roles in research is in the field of epigenetics, where it facilitates bisulfite sequencing by converting cytosine to uracil, allowing for detailed mapping of DNA methylation patterns—a crucial aspect of gene regulation studies. Additionally, sodium bisulfite is employed in environmental chemistry for the detoxification of heavy metals in waste streams, effectively reducing toxic metals like chromium and mercury to less harmful states. This dual functionality in both advanced genetic research and environmental management underscores its importance and versatility in scientific and industrial sectors.
