Chemical Properties

off-white powder

Uses

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).

Definition

ChEBI: 4-dodecylbenzenesulfonic acid is a member of the class dodecylbenzenesulfonic acids that is benzenesulfonic acid in which the hydrogen at position 4 of the phenyl ring is substituted by a dodecyl group.

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.
