Laboratory & Industrial Uses

• Biological Staining: Biologists use it as a stain to visualize cell nuclei, bacteria, DNA, and RNA under a microscope, as it binds to negatively charged cell components.
• Redox Indicator: In chemistry, it acts as a a redox (oxidation-reduction) indicator, changing color from blue (oxidized) to colorless (reduced) in the presence of certain agents.
• Aquaculture: Fish hobbyists use it as a treatment for fungal infections on fish eggs and to protect fish from nitrite poisoning.
• Dyeing Agent: It was originally developed as a synthetic dye for textiles like silk, wool, and cotton, and is still used for dyeing paper and other materials.

Methylene Blue (C.I. Basic Blue 9, C.I. 52015) is a classic, versatile thiazine dye, appearing as a dark green powder that gives a vibrant blue color in solution, used widely in textiles (silk, wool), paper, as a biological stain for nucleic acids, and even as a medical treatment (antidote, photosensitizer) due to its redox properties, staining negatively charged cell parts like DNA.
