General description

3,3′-Dichlorobenzidine is a persistent hydrophobic organic contaminant, found to be carcinogenic in nature and is released into the environment as an intermediate from dye manufacturing processes.

Application

3,3′-Dichlorobenzidine may be used as a certified reference standard for the quantification of the analyte and its congeners in environmental samples using high-performance liquid chromatography technique.
Refer to the product′s Certificate of Analysis for more information on a suitable instrument technique. Contact Technical Service for further support.

A simple, rapid, and reliable online methodology for the determination of benzidine and 3,3'-dichlorobenzidine (3,3'-DCB) in natural waters is proposed. The analytes are extracted and preconcentrated from aqueous samples in a small stainless steel precolumn packed with a polymeric PLRP-S
