Trimethylamine N-oxide

Trimethylamine N-oxide, or TMAO, is an amine oxide of trimethylamine that deep-sea fish accumulate to protect proteins from pressure and whose blood levels have been linked to heart disease.

Trimethylaminuria (TMAU, fish odor syndrome) is a metabolic disorder in which FMO3 enzyme deficiency leaves trimethylamine unoxidized, causing fishy odor in sweat, urine, and breath; managed by diet, antibiotics, and hygiene.

Trimethylglycine

Trimethylglycine (betaine, glycine betaine) is a zwitterionic quaternary ammonium compound, C5H11NO2, discovered in sugar beets; it acts as an osmolyte and methyl donor via BHMT, lowering homocysteine.

Trimethylolpropane

Trimethylolpropane (TMP), also called 2-ethyl-2-(hydroxymethyl)propane-1,3-diol, is a trifunctional polyol with three primary hydroxyl groups, used industrially in alkyd resins, saturated polyesters, polyurethanes, and synthetic jet engine lubricant esters.

Trimethylphosphine

Trimethylphosphine (PMe3) is the simplest tertiary phosphine, a colorless, flammable liquid that ignites in air and is best known as a strongly electron-donating ligand in organometallic chemistry.

Trimethylsilyl azide

Trimethylsilyl azide (azidotrimethylsilane, TMS-N₃) is a moisture-sensitive, flammable liquid used in organic synthesis as an azide transfer reagent, making triazoles and tetrazoles, and as a safer substitute for hydrazoic acid.

Trimethylsilyl chloride

Trimethylsilyl chloride (TMSCl), also called chlorotrimethylsilane, is a colorless, moisture-sensitive organosilicon liquid with formula (CH₃)₃SiCl, used to silylate alcohols in synthesis and as a catalyst in gas chromatography derivatization.

Trimethylsilyl cyanide

Trimethylsilyl cyanide (TMSCN) is an organosilicon compound used in organic synthesis as a convenient cyanide source, adding the CN group to carbonyl compounds and imines in reactions such as cyanosilylation and the Strecker synthesis.

Trimethylsilyl ether

A trimethylsilyl (TMS) ether is an organosilicon compound of the form R–O–Si(CH₃)₃, formed by protecting an alcohol or phenol; the least stable silyl protecting group, it is easily removed under mild conditions.

Trimethylsilyl trifluoromethanesulfonate

Trimethylsilyl trifluoromethanesulfonate (TMSOTf), also called trimethylsilyl triflate, is a colorless, moisture-sensitive liquid silylating agent and Lewis acid used in organic synthesis for enol ether formation, glycosylation, and acylation.

Trimethylsilylacetylene

Trimethylsilylacetylene, also called ethynyltrimethylsilane, is a volatile organosilicon liquid whose trimethylsilyl group caps acetylene, serving as a protected two-carbon building block in organic synthesis, most prominently in Sonogashira couplings.

Trimetrexate

Trimetrexate (Neutrexin, trimetrexate glucuronate) is a lipophilic non-classical folate antagonist and DHFR inhibitor used with leucovorin as alternative therapy for Pneumocystis pneumonia and tested as an anticancer agent.

Trimipramine

Trimipramine (Surmontil) is a sedating tricyclic antidepressant for depression, atypical in that its effect is not explained by monoamine reuptake inhibition; dosed 50-300 mg/day orally.

Trimix (breathing gas)

Trimix is a three-gas diving mixture of oxygen, nitrogen, and helium, used below about 60 m to reduce nitrogen narcosis and breathing resistance; hypoxic mixes need travel gases, and helium adds cost, heat loss, and HPNS risk.
