2-Sulfobenzaldehyde Sodium Salt is a sulfonated aromatic aldehyde used as a versatile intermediate in the synthesis of fluorescent dyes, surfactants, & specialty chemicals. This Sodium Salt has dual functionality (aldehyde and sulfonate) allows for selective reactivity in organic synthesis, especially in coupling reactions and anion exchange processes. As it preferred in Functional Intermediate in Dye and Surfactant Chemistry, 2-Sulfobenzaldehyde Sodium Salt enables synthesis pathways requiring both electron-withdrawing sulfonate groups and reactive aldehyde moieties. Manufacturers known it as Sodium o-formylbenzenesulfonate as frequently used in azo dye coupling, optical brighteners, and functional polymers demanding ionic conductivity or hydrophilic aromatic backbones.
