Methylene blue (methylthioninium chloride) is a phenothiazinium dye that cycles between an oxidized blue form and a reduced colorless (leuco) form. This makes it a standard redox indicator in biochemical and enzymatic assays. It is also a common biological stain and a photosensitizer used in light-activated photochemistry experiments.
This product is a 1% w/v aqueous solution (10 mg methylene blue per mL), supplied ready to dilute.
