High impact information on Tris-n-butylamine

• When performed in chloroform:methanol (2:1), extensive cleavage to water-soluble radioactive material occurred due to hydrolysis caused by the reaction medium, even when buffered with tributylamine [1].
• Amphetamine, ammonium chloride, tributylamine, and monensin, at concentrations that produce similar reductions in acidic pH gradients, increased dopamine release [2].
• [reaction: see text] o-(1-Alkynyl)benzaldimines react with aryl iodides and 1 atm of CO in the presence of tri-n-butylamine and a Pd(PPh(3))(4) catalyst to afford good yields of 3-substituted 4-aroylisoquinolines by acylpalladation of the carbon-carbon triple bond and cyclization [3].
• Functionally designed elastomeric nanofiber fabrics made of the equimolar copolyester, poly(L-lactide-co-epsilon-caprolactone) (PLCL), with type I collagen or the tri-n-butylamine salt of heparin (heparin-TBA) were co-electrospun using 1,1,1,3,3,3-hexafluoro-2-propanol (HFIP) as a solvent [4].
• As part of a study of mutagenic, reproductive and subchronic effects of these agents, we measured unscheduled DNA repair synthesis in isolated rat hepatocytes after exposure to GBI (stabilized with tributylamine), GBII (stabilized with diisopropylcarbodiimide) or GD [5].

Associations of Tris-n-butylamine with other chemical compounds

• ILM are equimolar mixtures of conventional MALDI matrix compounds such as 2,5-dihydroxybenzoic acid (DHB), alpha-cyano-4-hydroxycinnamic acid (CCA) or sinapinic acid (SA) together with organic bases [e.g., pyridine (Py), tributylamine (TBA) or N,N-dimethylethylenediamine (DMED)] [6].

Analytical, diagnostic and therapeutic context of Tris-n-butylamine

• The shapes of the titration curves depend on dendrimer generation, but in any case, the effect of the acid can be fully reversed by successive addition of a base (tributylamine) [7].
• Except for SPAM, the 3- and 4-sulfo-isomers of the analytes were separated by HPLC using volatile tributylamine as ion-pairing agent [8].
