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.

Other Notes

This Certified Reference Material (CRM) is produced and certified in accordance with ISO 17034 and ISO/IEC 17025. All information regarding the use of this CRM can be found on the certificate of analysis.

Laboratory experiments have been conducted to elucidate the photochemical behavior of 3,3'-dichlorobenzidine (DCB) and its congeners in aquatic systems. Photodechlorination of DCB was observed in aqueous samples that were irradiated with monochromatic radiation from a variable-wavelength laser at several wavelengths
