Methylene blue: complete encyclopedic guide
Welcome to this resource dedicated to methylene blue, a fascinating chemical compound whose history dates back to 1876. This guide offers an in-depth exploration of its properties, its practical applications and the contemporary scientific debates surrounding its therapeutic uses.
What is methylene blue?
Methylene blue is a synthetic dye belonging to the thiazine family. Discovered accidentally by the German chemist Heinrich Caro in 1876 during organic synthesis experiments, this compound quickly established itself as an indispensable tool in chemistry, biology and medicine. Its chemical formula C₁₆H₁₈ClN₃S characterises a cationic molecule with remarkable redox properties, which explains its versatility of use.
Today, methylene blue is experiencing a resurgence of scientific interest, particularly in the fields of neuroprotection, photodynamic therapy and metabolic approaches to cancer.
