CAS 76-05-1: Acido trifluoroacetico
Descrizione:
Acido trifluoroacetico (TFA) è un liquido incolore e pungente con la formula chimica C2HF3O2. È un acido organico forte, caratterizzato dalla presenza di tre atomi di fluoro attaccati alla struttura del carbonio, che aumenta significativamente la sua acidità rispetto all'acido acetico. Il TFA è altamente solubile in acqua e in molti solventi organici, rendendolo un reagente versatile in varie reazioni chimiche. La sua forte acidità è utilizzata nella sintesi organica, in particolare nella preparazione di derivati trifluoroacetilici e come catalizzatore in alcune reazioni. Il TFA è anche noto per la sua capacità di stabilizzare i carbanioni ed è comunemente usato nella sintesi di peptidi e nella chimica delle proteine. Tuttavia, è importante maneggiare il TFA con cura, poiché è corrosivo e può causare gravi ustioni al contatto con la pelle. Inoltre, il TFA è considerato ambientalmente persistente e il suo uso è regolamentato in alcune regioni a causa dei potenziali impatti ecologici. In generale, Acido trifluoroacetico è un composto prezioso sia in contesti industriali che di laboratorio, grazie alle sue uniche proprietà chimiche.

CAS:The combination of properties like solubility in most of the solvents, volatility, catalytic property, and strong acidity with non-oxidizing nature makes it a widely used reagent in organic synthesis. Trifluoroacetic acid is an important building block in the synthesis of pharmaceuticals, agrochemicals and performance products. It is a precursor to many fluorinated compounds, and widely used in peptide synthesis and other organic transformations involving deprotection of t-BOC group. TFA finds use as an ion pairing agent in liquid chromatography, as a solvent in NMR spectroscopy and as a calibrant in mass spectrometry.
