CAS 25561-30-2: bis(trimetilsilil)trifluoroacetamide

Descrizione: bis(trimetilsilil)trifluoroacetamide (CAS 25561-30-2) è un composto chimico comunemente usato come agente derivatizzante in chimica analitica, in particolare nella cromatografia gas e nella spettrometria di massa. Presenta un gruppo funzionale trifluoroacetamide, che migliora la volatilità e la stabilità termica degli analiti, rendendoli più facili da analizzare. Il composto è caratterizzato dalla sua alta reattività grazie alla presenza del gruppo trifluoroacetamide, che può formare derivati stabili con vari gruppi funzionali, inclusi alcoli e ammine. La sua struttura include due gruppi trimetilsililici, che contribuiscono alla sua capacità di proteggere gruppi funzionali sensibili durante l'analisi. bis(trimetilsilil)trifluoroacetamide è tipicamente un liquido incolore o giallo pallido con un odore distintivo. È solubile in solventi organici ed è generalmente stabile in condizioni di laboratorio standard. Tuttavia, deve essere maneggiato con cura a causa del suo potenziale di liberare gas tossici durante la decomposizione. Si raccomandano misure di sicurezza adeguate, incluso l'uso di dispositivi di protezione individuale, quando si lavora con questo composto.
