Triflic acid, the short name for trifluoromethanesulfonic acid, TFMS, TFSA, HOTf or TfOH, is a sulfonic acid with the chemical formula CF 3 SO 3 H. It is one of the strongest known acids. Triflic acid is mainly used in research as a catalyst for esterification. [2] [3] It is a hygroscopic, colorless, slightly viscous liquid and is soluble in ...
Trimethylsilyl trifluoromethanesulfonate ( TMSOTf) is an organosilicon compound with the formula (CH3)3SiO3SCF3. It is a colorless moisture-sensitive liquid. It is the trifluoromethanesulfonate derivative of trimethylsilyl. [1] It is mainly used to activate ketones and aldehydes in organic synthesis .
Trifluoromethanesulfonic anhydride, also known as triflic anhydride, is the chemical compound with the formula (CF 3 SO 2) 2 O. It is the acid anhydride derived from triflic acid. This compound is a strong electrophile, useful for introducing the triflyl group, CF 3 SO 2. Abbreviated Tf2O, triflic anhydride is the acid anhydride of the ...

Tetramethylsilane (abbreviated as TMS) is the organosilicon compound with the formula Si (CH 3) 4. It is the simplest tetraorganosilane. Like all silanes, the TMS framework is tetrahedral. TMS is a building block in organometallic chemistry but also finds use in diverse niche applications.
Trifluoromethyltrimethylsilane (known as Ruppert-Prakash reagent, TMSCF 3) is an organosilicon compound with the formula CF 3 Si (CH 3) 3. It is a colorless liquid. The compound is a reagent used in organic chemistry for the introduction of the trifluoromethyl group. The compound was first prepared in 1984 by Ingo Ruppert [1] and further ...
It has a relatively short elimination half-life and mean residence time of 2 days and 4 days, respectively. As such, it has a short duration of action and must be administered two to three times per week. Intramuscular injection of testosterone propionate as an oil solution, aqueous suspension, and emulsion has been compared.
The Exotic Shorthair sub-breed qualifies for every cat coat variation that TICA recognises. Eye colours range widely and may include blue, copper, odd-eyed blue and copper, green, blue-green, and hazel. Various TICA and CFA coat categorisations come with specific eye-colour requirements.
