Dimethoate

Dimethoate is a systemic organophosphate insecticide and acaricide, introduced on the market in 1956 to control insects including mites, flies, aphids, and plant hoppers; it kills by inhibiting acetylcholinesterase.

Dimethomorph

Dimethomorph (CAS 110488-70-5) is a systemic fungicide of the CAA group, used against oomycete pathogens; the European Commission denied its EU approval in 2024 over toxicity.

Dimethoxyethane

Dimethoxyethane, formally 1,2-dimethoxyethane and commonly called monoglyme, is a colorless, water-miscible ether used as an aprotic solvent in organic synthesis and as the principal ether solvent in lithium battery electrolytes.

Dimethyl carbonate

Dimethyl carbonate, also called carbonic acid dimethyl ester, is a colorless, flammable liquid ester of carbonic acid used as a green methylating agent, solvent, and battery electrolyte co-solvent.

Dimethyl carbonate synthesis from carbon dioxide

Dimethyl carbonate synthesis from carbon dioxide converts CO₂ and methanol into dimethyl carbonate (DMC), directly or via intermediates like ethylene carbonate; low yields from water formation remain the main obstacle.

Dimethyl disulfide

Dimethyl disulfide is a colorless, oily organosulfur liquid with a garlic-like odor, the most commonly used sulfiding agent for activating petroleum refining catalysts and, under the name Paladin, a preplant soil fumigant.

Dimethyl ether

Dimethyl ether (DME, CH₃OCH₃), also called methoxymethane, is the simplest ether, a highly flammable gas used mainly as an aerosol propellant and studied as a soot-free alternative diesel fuel.

Dimethyl ether as an extraction solvent

Dimethyl ether (methoxymethane) as an extraction solvent: a low-boiling liquefied gas that extracts both polar and non-polar food components; FDA GRAS (GRN 741) and EFSA-assessed with residual limits of 3 mg/kg and 9 μg/kg.

Dimethyl fumarate

Dimethyl fumarate (DMF, Skilarence, Fumaderm, Tecfidera) is an oral fumaric acid ester immunomodulator; its active metabolite monomethyl fumarate treats moderate-to-severe plaque psoriasis and relapsing-remitting multiple sclerosis.

Dimethyl labeling

Dimethyl labeling is a chemical labeling method for quantitative proteomics in which peptide N-termini and lysine amines are reductively dimethylated with formaldehyde isotopologues, comparing protein abundance across two to five samples in one LC-MS experiment.

Dimethyl malonate

Dimethyl malonate is the dimethyl ester of malonic acid, a colorless liquid whose acidic central methylene underlies the malonic ester synthesis used to build pharmaceuticals and fragrances.

Dimethyl methylphosphonate

Dimethyl methylphosphonate (DMMP) is a colorless, water-miscible organophosphorus compound used mainly as an additive flame retardant and as the standard simulant for nerve agents such as sarin in detector testing.

Dimethyl oxalate

Dimethyl oxalate is the dimethyl ester of oxalic acid, a crystalline solid made industrially by coupling carbon monoxide with methyl nitrite and hydrogenated to ethylene glycol.

Dimethyl phthalate

Dimethyl phthalate (DMP) is the dimethyl ester of phthalic acid, a colorless oily liquid used as a plasticizer and solvent and once widely as an insect repellent.
