2-Formylbenzenesulfonic acid sodium salt Usage And Synthesis

Chemical Properties	white to beige crystalline powder
Uses	2-Formylbenzenesulfonic acid sodium salt was used as precursor to test the ability of fungal strains for transformation of phenolic and non-phenolic precursors into stable and non-toxic dyes.
General Description	2-Formylbenzenesulfonic acid sodium salt reacts with chitosan in the presence of sodium cyanoborohydride to yield N-benzyl derivatives.
Purification Methods	It forms prisms or plates by extracting with boiling EtOH, filtering, evaporating to dryness and recrystallising the Na salt from a small volume of H2O. The N-phenylhydrazone sodium salt recrystallises from H2O with m 174.5o. [Gnehm & Schüle Justus Liebigs Ann Chem 299 363 1898, Beilstein 11 IV 652.]
