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 .
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 ...
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 ...
The TICA show season runs from May 1 to April 30 of a given year at which point all Regional and International Award points are reset. All TICA shows are open to the public. A TICA cat show is a number of smaller shows all running at the same time in various “rings” throughout the show hall.
Time-of-flight mass spectrometry. Time-of-flight mass spectrometry ( TOFMS) is a method of mass spectrometry in which an ion 's mass-to-charge ratio is determined by a time of flight measurement. Ions are accelerated by an electric field of known strength. [1] This acceleration results in an ion having the same kinetic energy as any other ion ...
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 ...
TFMS is the primary automation system used by the Air Traffic Control System Command Center and nationwide traffic management units to regulate air traffic flow, manage throughput, and plan for future air traffic demand. TFMS's 31 tools exchange information and support other DSS through System Wide Information Management (SWIM). The FAA ...
