Trifluoroacetic acid as excipient destabilizes melittin causing the selective aggregation of melittin within the centrin-melittin-trifluoroacetic acid complex
(American Crystallographic Association, 2015-05)
Trifluoroacetic acid (TFA) may be the cause of the bottleneck in high resolution structure determination for protein-peptide complexes. Fragment based drug design often involves the use of synthetic peptides which contain ...
Separation of four isomeric tropane alkaloids from Schizanthus grahamiii by non-aqueous capillary electrophoresis
(2005)
The potential of non-aqueous capillary electrophoresis was investigated for the separation of four isomeric tropane alkaloids, namely 3α-senecioyloxy-7β-hydroxytropane, 3α-hydroxy-7β-senecioyloxytropane, 3α-hydroxy-7β-an ...
Infrared study of trifluoroacetic acid unpurified synthetic peptides in aqueous solution: Trifluoroacetic acid removal and band assignment
(Academic Press Inc Elsevier Science, 2011-03)
Synthetic peptide or protein samples are mostly unpurified with trifluoroacetic acid (TFA) used during the synthesis procedure, which strongly interferes with structure determination by infrared (IR) spectroscopy. The aim ...
Enthalpies of reaction of lanthanide trifluoroacetate trihydrate with 2-azacyclononanone to form lanthanide trifluoroacetate-tris 2-azacyclononanone
(Elsevier Science BvAmsterdamHolanda, 2007)
PREPARATION OF (+)-alpha-TERPINEOL FROM (+)-LIMONENE: MONOTERPENES WITH PLEASANT ODOR IN A PROJECT FOR UNDERGRADUATE ORGANIC CHEMISTRY LABORATORY.

Trifluoroselenoacetic acid, CF3C(O)SeH: Preparation and properties
(American Chemical Society, 2010-09-29)
The hitherto unknown trifluoroselenoacetic acid was prepared through the reaction of trifluoroacetic acid with Woollins' reagent. The compound was fully characterized by mass spectrometry, 1H, 19F, 77Se, and 13C NMR, ...
Trifluoroacetic acid and trifluoroacetic anhydride radical cations dissociate near the ionization limit
(American Chemical Society, 2019-06)
The threshold photoelectron spectra (TPES) and ion dissociation breakdown curves for trifluoroacetic acid (TFA) and trifluoroacetic anhydride (TFAN) were measured by imaging photoelectron photoion coincidence spectroscopy ...
Analysis of total glucosinolates and chromatographically purified benzylglucosinolate in organic and conventional vegetables
(2013-01-01)
The limited availability of foods that are free of pesticides has led Brazil to search for alternative production methods to meet the desires of consumers. Currently, organic cultivation represents a production system that ...
