• Canonical SMILES: CC(CBr)Br
• Uses: 1,2-Dibromopropane is used in organic synthesis and solvent. It was used to study the effect of reductant concentration, reductant contact time and suspension pH on reductive dechlorination of carbon tetrachloride by soil manipulated with Fe(II) and HS-. It was used as internal standard during the determination of nitrogenous disinfection byproduct trichloronitromethane by gas chromatography mass spectrometry.
