Find out more about methoxy chlorobiphenyls

Methoxy chlorobiphenyl is an organic molecule of the substituted biphenyl family, containing both a methoxy group (-OCH₃) and one or more chlorine atoms on a biphenyl skeleton (two linked benzene rings).

Applications and benefits

These compounds can be:

synthesis intermediates in organic chemistry.
models for studying methylated or hydroxylated PCBs, particularly in environmental or toxicological contexts.

Some derivatives are being studied for their biological activity, or as transformation products of PCBs in the body.

Solutions prepared by Wellington Labs

The range of MeO-PCBs offered by Wellington Laboratories includes:

Individual compounds: specific MeO-PCBs, each with a defined position of the methoxy group and chlorine atoms on the biphenyl backbone.
Mixtures in solution: prepared in nonane, with concentrations and chemical purity greater than 98%, for precise quantitative analysis.
Isotopically labelled solutions: used as internal standards to improve the precision of analytical methods.
