What does TBA stand for?

HPLC methods applying the reversed phase technique, where the eluating buffer solution is supplemented by a large hydrophobic cationic, typically a tetrabutylammonium (TBA) compound, were probably first used for the separation of nucleotides by Juengling and Kammermeier (1980), who applied two separate isocreatic runs in different conditions to resolve Cr, PCr, and adenine nucleotides.

2], and tetrabutylammonium trifluoromethane-sulfonate (99%) were used without further purification.

2 wt% tetrabutylammonium bromide salt (tBAB) in 1:1 pX/CH solvent mixture.

2]en]+), using tetrabutylammonium tetrachloroaurate (TBA-Au[Cl.

That this downfield shift was due to the cations and not due to counter anions (perchlorate or hexafluorophosphate) was unequivocally confirmed by examining the effect of the addition of tetrabutylammonium perchlorate (TBA.

Briefly, tetrabutylammonium hydrogen sulfate is added as an ion-pairing reagent to the homogenized tissues, and the analyte ion pair is partitioned into methyl-tert-butyl ether.

20 M tetrabutylammonium hexafluorophosphate/dimethyl sulfoxide results in a well adhering, continuous and microscopically rough surfaces.

Deprotection of the TBS group with tetrabutylammonium fluoride afforded sitophilure 1 (89% yield, 42% overall yield, and 97% ee, based on the reported rotation of +27.
