Methylene blue (methylthioninium chloride) is an organic-synthetic, basic and cationic dye derived from phenothiazine. It is available as a dark blue, crystalline powder that dissolves in water to form a vibrant blue solution.
Our methylene blue is distinguished by its exceptional purity. This synthetic blue dye is pharmaceutical-grade (99.8% purity) and dissolved in 99% purified water. As a result, this 1% aqueous solution is ideal for scientific purposes, laboratory applications, and research use. The solution is supplied in a light-protected amber glass bottle with a precise dropper.
