Methyl salicylate ( oil of wintergreen or wintergreen oil ) is an organic ester that is naturally produced by many species of plants.

Methyl salicylate can be produced by esterifying salicylic acid with methanol.

Methyl salicylate is used in high concentrations as a rubefacient in deep heating liniments ( such as Bengay ) to treat joint and muscular pain.

Methyl salicylate is among the compounds that attract male orchid bees, who apparently gather the chemical to synthesize pheromones ; it is commonly used as bait to attract and collect these bees for study.

Methyl salicylate has the ability to clear plant or animal tissue samples of color, and as such is useful for microscopy and immunohistochemistry when excess pigments obscure structures or block light in the tissue being examined.

Methyl salicylate, though its source plants are not true mints, is used as a mint in some kinds of chewing gum and candy, as an alternative to the more common peppermint and spearmint oils.

Methyl salicylate can be used as a transfer agent, to produce a manual copy of an image on a surface.

Methyl salicylate is added in small amounts to glacial acetic acid to lower its freezing point for transport in cold countries.

Methyl salicylate is used as a simulant or surrogate for the research of chemical warfare agent sulfur mustard, due to its similar chemical and physical properties.

Methyl phenyl ether is anisole, because it was originally found in aniseed.

Methyl group is an alkyl derived from methane, containing one carbon atom bonded to three hydrogen atoms — CH < sub > 3 </ sub >.

Methyl is the IUPAC nomenclature of organic chemistry term for an alkane ( or alkyl ) molecule, using the prefix " meth -" to indicate the presence of a single carbon.

Methyl bromide is a controversial fumigant.

The most common form uses methanol ( converted to sodium methoxide ) to produce methyl esters ( commonly referred to as Fatty Acid Methyl Ester-FAME ) as it is the cheapest alcohol available, though ethanol can be used to produce an ethyl ester ( commonly referred to as Fatty Acid Ethyl Ester-FAEE ) biodiesel and higher alcohols such as isopropanol and butanol have also been used.

Methyl palmitate, which has been extracted from green husks of J. regia has insecticidal properties: at a concentration of 10 mg / ml, it killed 98 % of Tetranychus cinnabarinus ( carmine spider mites ) in one study.

Methyl butyrate is present in small amounts in several plant products, especially pineapple oil.

Methyl bromide was among the most widely used fumigants until its production and use was restricted by the Montreal Protocol due to its role in ozone depletion.

Methyl iodide had been approved for use as a pesticide by the United States Environmental Protection Agency in 2007 as a pre-plant biocide used to control insects, plant parasitic nematodes, soil borne pathogens, and weed seeds.

Methyl iodide can also be prepared by the reaction of methanol with potassium iodide, catalyzed by acid:

Methyl red is classed by the IARC in group 3-unclassified as to carcinogenic potential in humans.

As an azo dye, Methyl Red may be prepared by diazotization of anthranilic acid, followed by reaction with dimethylaniline:

In microbiology, methyl red is used in the Methyl Red ( MR ) Test, used to identify bacteria producing stable acids by mechanisms of mixed acid fermentation of glucose ( cf.

Methyl isocyanate was the causative agent in the Bhopal Disaster that killed thousands of people.

Methyl iodide, a naturally occurring substance, however, does not have ozone-depleting properties and the United States Environmental Protection Agency has designated the compound a non-ozone layer depleter.

Methyl parathion, malathion, and pyrethroids were subsequently used, but environmental and resistance concerns arose as they had with DDT and control strategies changed.

Methyl violet can be formulated to change from orange to green, or orange to colorless.
