Methylene blue is a monoamine oxidase inhibitor (MAOI) [39] and, if infused intravenously at doses exceeding 5 mg/kg, may result in serotonin syndrome if combined with any selective serotonin reuptake inhibitors (SSRIs) or other serotonergic drugs (e.g., duloxetine, sibutramine, venlafaxine, clomipramine, imipramine). [40]
Methyl blue is a chemical compound with the molecular formula C 37 H 27 N 3 Na 2 O 9 S 3.It is used as a stain in histology, [1] and stains collagen blue in tissue sections. It can be used in some differential staining techniques such as Mallory's trichrome stain and Gömöri trichrome stain, and can be used to mediate electron transfer in microbial fuel cells.

New methylene blue (also NMB) [clarify] is an organic compound of the thiazine class of heterocycles. It is used as a stain and as an antimicrobial agent. It is classified as an azine dye, and the chromophore is a cation, the anion is often unspecified.
A methylene blue active substances assay, or MBAS assay, is a colorimetric analysis test method that uses methylene blue to detect the presence of anionic surfactants (such as a detergent or foaming agent) in a sample of water. An anionic surfactant detected by the color reaction is called a methylene blue active substance (MBAS). [1]
Dimethyl-4-phenylenediamine can be converted to methylene blue by reaction with dimethylaniline and sodium thiosulfate in several steps: [3] It is used as accelerator for the vulcanization of rubber, being first converted to the corresponding mercaptobenzothiazole.
The Wayson stain is a basic fuchsin-methylene blue, ethyl alcohol-phenol microscopic staining procedure. It was originally a modified methylene blue stain used for diagnosing bubonic plague. [1] With this stain, Yersinia pestis appears purple with a characteristic safety-pin appearance, [2] which is due to the presence of a central vacuole.
The original sources of azure B (one of the oxidation products of methylene blue) were from polychromed methylene blue solutions, which were treated with oxidizing agents or allowed to naturally age in the case of Romanowsky. [3] [13] Ernst Malachowsky in 1891 was the first to purposely polychrome methylene blue for use in a Romanowsky-type stain.
