Grignard degradation at one time was a tool in structure elucidation in which a Grignard RMgBr formed from a heteroaryl bromide HetBr reacts with water to Het-H (bromine replaced by a hydrogen atom) and MgBrOH. This method allows the determination of the number of halogen atoms in an . In modern usage Grignard degradation is used in the chemical analysis of certain triacylglycerols.

A side reaction may take place in the reaction between phenylmagnesium bromide and ..

The Grignard reagent is readily prepared from 4-bromo--dimethylaniline. Addition of this Grignard reagent to diethyl carbonate, followed by acid hydrolysis gives the triarylmethane dye Crystal Violet. Addition of the Grignard reagent to methyl benzoate, followed by acid hydrolysis gives the dye Malachite Green. A procedure suitable for an undergraduate laboratory course is presented.
