NATIVE and MASS-LABELLED HALOGENATED CARBAZOLES - Reference Standards

Wellington Laboratories Logo    Wellington Laboratories Catalogue Image


Halogenated carbazoles have recently been recognized as emerging environmental contaminants, but research groups have been reporting their existence in environmental samples since 1984. There may be multiple sources of these pollutants, but it has recently been suggested that they were produced as by- products during the synthesis of halogenated indigo dyes. Since unsubstituted carbazoles are known to be lost during acid silica clean-up, it is very important that reference standards be used when processing samples.

In order to aid researchers in the detection of halogenated carbazoles in environmental samples, Wellington has produced certified reference standards of selected halogenated carbazoles (CCZ-3, CCZ-36, CCZ-1368, CCZ-2367, BCZ-3, BCZ-27, BCZ-136, BCZ-1368, 1-B-36-CCZ, and 18-B-36-CCZ) as well as two certified reference standards of mass-labelled chlorinated carbazoles (MCCZ-36 and MCCZ-1368).
