General description

4-Dodecylbenzenesulfonic acid (DBSA) is an alkyl sulfonate. It participates in the preparation of a polymer along with polystyrene-block-poly(4-vinylpyridine) and a comb-coil A-block-(B-graft-C) type of copolymer.

Application

4-Dodecylbenzenesulfonic acid (p-dodecylbenzenesulfonic acid, DBSA) may be used:
  • As a solvent for the synthesis of 2-(1,5-diaryl-1,4-pentadien-3-ylidene)-hydrazinecarboximidamide hydrochlorides.
  • In situ coating of rutile nanoparticles.
  • As a stabilizer in the preparation of colloidal CdS.
  • In the fabrication of solid-state dye-sensitized solar cells (DSSCs).
