Description

N,N'-Dicyclohexylcarbodiimide is a carboxyl activating reagent used in peptide synthesis. It acts as a dehydrating agent for the preparation of amides, ketones and nitriles. It is involved in the preparation of esters by reacting tertiary alcohols with carboxylic acid. It is utilized for the stereo chemical inversion of secondary alcohols by forming formyl ester followed by saponification. It is associated with dimethyl sulfoxide and used in Pfitzner-Moffatt oxidation to convert alcohols into aldehydes and ketones.

The original Alfa Aesar product / item code or SKU reference has not changed as a part of the brand transition to Thermo Scientific Chemicals.

Applications
Le N,N′-Diccyclohexylcarbodiimide est un réactif d’activation carboxylique utilisé dans la synthèse des peptides. Il agit comme agent déshydratant pour la préparation d’amides, de cétones et de nitriles. Il est impliqué dans la préparation des esters en faisant réagir les alcools tertiaires avec de l’acide carboxylique. Il est utilisé pour l’inversion chimique stéréophonique des alcools secondaires en formant un ester formyle suivi de la saponification. Il est associé au diméthylsulfoxyde et utilisé dans l’oxydation de Pfitzner-Moffatt pour convertir les alcools en aldéhydes et cétones.

Solubilité
Soluble dans le méthanol, le chloroforme, le dichlorométhane, l’acétonitrile, le tétrahydrofurane et le diméthylformamide. Insoluble dans l’eau.

Remarques
Incompatible avec les agents oxydants forts.
