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 ...
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 ...

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 that has the same charge.
Solid State Interlocking. A GEC-manufactured SSI interlocking cubicle. Solid State Interlocking (SSI) is the brand name of the first generation processor-based interlocking developed in the 1980s by British Rail's Research Division, GEC-General Signal and Westinghouse Signals Ltd in the UK.
TFM (3- trifluoromethyl -4- nitrophenol) is a common piscicide, i.e., a fish poison used to combat parasitic and invasive species of fish. [1] The substance was discovered in 1958 when researching means to combat sea lampreys and it currently remains the primary lampricide (lamprey-killer) in the Great Lakes area. [1]
