Methylene blue Use and Manufacturing

Methods of Manufacturing

Taking N, N-dimethylaniline as the main raw material, it is first nitrosated to reduce p-aminodimethylaniline, then oxidized by Na2Cr2O7.Na2S2O3, vulcanized and condensed to obtain thiazine, and finally formed into salt with ZnCl2, after salting out , Filter and dry to get the finished product. .

Uses

A useful inhibitor of cGMP-mediated processes and a useful stain
