Aromatic chemical

Methylene blue, with the formula C16H18SCl, is a heterocyclic aromatic compound used in a variety of fields, from biology to chemistry. Curiously, as a solid it forms an odourless green powder, which produces a deep blue solution when dissolved in water. Should not be confused with methyl blue or methyl violet, which are common stain and pH indicators.

Many different applications

This compound has many different uses, ranging from redox indictor to treatment for malaria:

  • Widely used as a redox indicator: solution turns from blue to colourless in the presence of a reducing compound
  • Can also be used as a peroxide generator: releases a single oxygen atom when exposed to light
  • Water testing: Known as an MBAS assay, it can detect surfactants, such as phosphates, sulfonates, carboxylates or sulphates
  • Used as a dye in many biology-related areas: Can be used to stain RNA and DNA or differentiate between live and dead cells, for example.
  • Used to treat fungal infections in fish
  • Common ingredient in drugs prescribed as urinary analgesic and anti-spasmodic
  • Was used as a treatment for malaria, but has been replaced with alternative treatments as most patients disliked that fact that it turned urine green
  • Can be used in the treatment of carbon monoxide poisoning
  • Used in the treatment of blood disorder, methemoglobinemia
  • Very useful in cases of extremely low blood pressure after heart surgery, such as cardiac by-pass
  • Used in the treatment of potassium cyanide poisoning
  • Used as a dye in various situations, from detecting urinary leaks to endoscopies to remove polyps
  • Recently used in a new drug to prevent the development of Alzheimer’s disease
