Trifluoroacetic Acid Anhydride

Trifluoroacetic Acid Anhydride is the acid anhydride of trifluoroacetic acid. In particular, trifluoroacetic anhydride is the perfluorinated derivative of acetic anhydride. It may be prepared from trifluoroacetic acid by dehydrating with excess α-halogenated acid chlorides. Trifluoroacetic Acid Anhydride provides a convenient way to introduce a trifluoromethyl group into an organic compound. It is used in the production of agricultural and pharmaceutical molecules. It has been found to be an effective esterification promoter in the preparation of experimental quantities of partial cellulose acetates in which the fibrous structure of the original cotton is retained.

Trifluoromethanesulfonic Anhydride

Trifluoromethanesulfonic anhydride is a strong electrophile useful for introducing the triflyl group.It will convert phenols into a triflic ester, which enables cleavage of the c-o bond.

Trifluridine

Trifluridine is an antiviral derivative of thymidine used mainly in the treatment of primary keratoconjunctivitis and recurrent epithelial keratitis due to herpes simplex virus.Trifluridine interferes with DNA synthesis in cultured mammalian cells. Trifluridine presumably stops replication of herpes viral DNA in 3 ways: 1) competitive inhibition of viral DNA polymerase, 2) incorporation into and termination of the growing viral DNA chain, and 3) inactivation of the viral DNA polymerase. Trifluridine targets HSV and VSV thymidine kinase.

Triglycerides

Triglycerides is an ester derived from glycerol and three fatty acids.Triglycerides are formed by combining glycerol with three molecules of fatty acid.Triglycerides, as major components of very-low-density lipoprotein (VLDL) and chylomicrons, play an important role in metabolism as energy sources and transporters of dietary fat.Triglycerides are split into monoacylglycerol and free fatty acids in a process called lipolysis, with the secretion of lipases and bile, which are subsequently moved to absorptive enterocytes, cells lining the intestines. The triglycerides are rebuilt in the enterocytes from their fragments and packaged together with cholesterol and proteins to form chylomicrons.Triglycerides cannot pass through cell membranes freely. Special enzymes on the walls of blood vessels called lipoprotein lipases must break down triglycerides into free fatty acids and glycerol. Fatty acids can then be taken up by cells via the fatty acid transporter (FAT).Triglycerides are also split into their components via transesterification during the manufacture of biodiesel. The resulting fatty acid esters can be used as fuel in diesel engines.

Triiodomethane

Triiodomethane is the organoiodine compound. It has a penetrating odor and, analogous to chloroform, sweetish taste. It is occasionally used as a disinfectant. Around the beginning of the 20th century it was used in medicine as a healing and antiseptic dressing for wounds and sores, although this use is now superseded by superior antiseptics. It is the active ingredient in many ear powders for dogs and cats, to prevent infection and facilitate removal of ear hair, along with zinc oxide and propanoic acid.

Trimagnesium Dicitrate

Trimagnesium dicitrate is a salt of magnesium and citric acid. It is used as a source of magnesium and is an active ingredient in acid-base balanced products. It is also used for the treatment of hypomagnesemia in pharmaceutical preparations.

Properties Suppliers
Trimebutine

Trimebutine is a drug with antimuscarinic and weak mu opioid agonist effects. The major product from drug metabolism of trimebutine in human beings is nor-trimebutine, which comes from removal of one of the methyl groups attached to nitrogen.

Properties Suppliers
Trimegestone

Trimegestone is a steroidal progestin of the 19-norprogesterone group related to promegestone. Trimegestone has very high affinity for the progesterone receptor, only weak affinity for the mineralocorticoid receptor, and little or no affinity for other steroid hormone receptors. It is used as a hormonal contraceptive and in hormonal replacement therapy for postmenopausal symptoms.

Trimellitic Anhydride

Trimellitic Anhydride is used in the production of resins for electrode-position and powder coatings, and as a binder for glass fibres, and other aggregates. It is used as an embossing agent for vinyl flooring and as a curing agent for epoxy resins. It is also used as an intermediate for the synthesis of surface coatings chemicals, adhesives, polymers, dyes printing inks, pharmaceuticals and agrochemicals.
