Descrizione

Descrizione generale

(R)-(+)-a-Methylbenzyl isocyanate [(R)-(+)-MBIC] is a derivatizing agent.

Applicazioni

(R)-(+)-MBIC has been used in derivatization of 4-(methylnitrosamino)-1-(3-pyridyl)-1-butanol to form 4-(methylnitrosamino)-1-(a-methylbenzylcarbamoyl)-1-(3-pyridyl)butane. It has also been used in isolating hydroxyl acid, converting it to Methyl-4-[(S)-a-methylbenzylcarbamoyl]-4-(3-pyridyl)- butanoate which was further analysed by LC-MS/MS.1 It reacts with hydrate hydrochloride ketoaniline to yield hemiaminal, 3-((1R)-1-Phenylethyl)-(4S)-6-chloro-4-hydroxy-4-(trifluoromethyl)-1,3,4-trihydroquinazolin-2-one.
