Methanol is a colorless, flammable liquid used in the manufacture of formaldehyde and acetic acid, in chemical synthesis, antifreeze, and as a solvent. Ingestion of methanol is toxic and may cause blindness. It is the simplest alcohol, and is a light, volatile, colourless, flammable, poisonous liquid with a distinctive odor that is somewhat milder and sweeter than ethanol . Methanol is responsible for accidental, suicidal, and epidemic poisonings, resulting in death or permanent sequelae. Toxicity is due to the metabolic products of alcohol dehydrogenase (ADH) and aldehyde dehydrogenase. The rapid and accurate diagnosis of toxic alcohol poisoning due to methanol (methyl alcohol) is paramount in preventing serious adverse outcomes. The quantitative measurement of specific serum levels of methanol using gas chromatography is expensive, time consuming and generally only available at major tertiary-care facilities.
