CAS 1099-45-2

Acetato di etil trifenilfosforanilideno

Descrizione:

Acetato di etil trifenilfosforanilideno, con il numero CAS 1099-45-2, è un composto organofosforato caratterizzato dalla sua struttura unica, che include un gruppo fosforanilidene legato a un moiety di acetato di etile. Questo composto appare tipicamente come un solido o un liquido viscoso ed è noto per il suo ruolo come reagente nella sintesi organica, in particolare nella formazione di legami carbonio-carbonio. Mostra una stabilità moderata in condizioni standard, ma può decomporsi sotto calore estremo o in presenza di acidi o basi forti. Acetato di etil trifenilfosforanilideno è spesso utilizzato nella reazione di Wittig, dove agisce come un ylide di fosfonio, facilitando la conversione di composti carbonilici in alcheni. La sua reattività è influenzata dalle proprietà donatrici di elettroni del gruppo trifenylofosfina, che ne aumenta la nucleofilia. I dati di sicurezza indicano che deve essere maneggiato con cura, poiché può comportare rischi per la salute se ingerito o inalato, richiedendo misure di sicurezza appropriate durante l'uso.

CAS: 1099-45-2

(Carbethoxymethylene)triphenylphosphorane is a pharmacological treatment that has a water-vapor reaction mechanism. It inhibits the replication of DNA by binding to the nitrogen atom in fatty acid, forming a heterocyclic compound with a hydroxyl group, which prevents the formation of ATP. This drug also binds to monoamine neurotransmitters and light emission. (Carbethoxymethylene)triphenylphosphorane is used to treat patients with Parkinson's disease, Alzheimer's disease, and other neurodegenerative diseases.
