Atomfair Ethanesulfonic acid, 2-bromo-, sodium salt (1:1) C2H4BrNaO3S CAS 4263-52-9

Description

Sodium 2-bromoethanesulfonate (CAS No. 4263-52-9) is a high-purity organic sulfonate compound with the molecular formula C₂H₄BrNaO₃S. This white to off-white crystalline powder is widely utilized in biochemical and pharmaceutical research due to its reactive bromoethyl functional group. With a molecular weight of 211.01 g/mol, it offers excellent solubility in water and polar organic solvents, making it ideal for nucleophilic substitution reactions. The product is rigorously tested for purity (typically ≥95-98%) and is supplied in sealed containers to ensure stability and prevent moisture absorption. Suitable for use as an alkylating agent or intermediate in organic synthesis, it is particularly valuable in the preparation of sulfonate-based ionic liquids and bioactive molecules. Store in a cool, dry place away from strong oxidizing agents.
