General description

Methylene violet 3RAX [MV3RAX, 3-amino-7-(diethylamino)-5-phenyl phenazinium chloride] is a phenazinium dye and is cationic in nature. It has several applications in staining chemistry. Methylene violet 3RAX dye has an antimalarial property. It is used as a probe for investigating guest–host interactions in dendrimers and this may have relevance in drug–DNA interactions.

Application

Methylene Violet 3RAX has been used as a reagent in a preparation of citrate methylene violet, which is used for staining yeast cells. It is also used as an internal standard in tandem mass spectrometry (MS/MS) for the quantification of methylene blue in blood samples.
