CAS 3849-21-6

Etil 2-ciano-2-(idrossimino)acetato

Descrizione:

Etil 2-ciano-2-(idrossimino)acetato, con il numero CAS 3849-21-6, è un composto organico caratterizzato dai suoi gruppi funzionali, tra cui un gruppo ciano e un gruppo idrossimino. Questo composto appare tipicamente come un liquido o solido incolore o giallo pallido, a seconda della sua purezza e forma. È solubile in solventi organici polari, il che facilita il suo utilizzo in varie reazioni chimiche. Etil 2-ciano-2-(idrossimino)acetato è spesso utilizzato nella sintesi organica, in particolare nella preparazione di vari derivati e come intermediario nella sintesi di prodotti farmaceutici e agrochimici. La presenza del gruppo ciano contribuisce alla sua reattività, permettendogli di partecipare a reazioni di addizione nucleofila. Inoltre, il gruppo idrossimino può impegnarsi in tautomerizzazione, influenzando la reattività e la stabilità del composto. Devono essere adottate precauzioni di sicurezza quando si maneggia questa sostanza, poiché può comportare rischi per la salute se ingerita o inalata, e deve essere utilizzato un adeguato equipaggiamento di protezione.

Oxyma

CAS: 3849-21-6

Ethyl isonitrosocyanoacetate, generally known as Oxyma or OxymaPure, is an additive used in amide coupling reactions as a racemisation suppressant. Oxyma is a safe alternative to the explosive HOAt and HOBt and is mainly used in combination with the carbodiimides EDCI, DCC or DIC. Oxyma is stable, can be used in solution, solid-phase and microwave-assisted synthesis, has great capacity to inhibit epimerisation, excellent coupling efficiencies and shows no risk of capping the resin or the peptide upon hydrolysis of the ethyl ester.

Oxyma Pure®

CAS: 3849-21-6

OxymaPure® is a hydrogen bond-based molecular probe that binds to the hydroxamic acid group of bacterial cell walls. It has been shown to have an antibacterial activity against Staphylococcus aureus and Escherichia coli. OxymaPure® is soluble in water, making it suitable for oral administration. The safety profile of OxymaPure® includes studies in rats, indicating that it does not cause any toxic effects at doses up to 2000 mg/kg body weight. OxymaPure® can be synthesized on a solid phase by using carbodiimides as reactive agents and linkers as additive materials. This process is relatively rapid and produces high yields of the desired product.
