CAS 100367-55-3: 2-Cyano-5-nitropyridine

2-Cyano-5-nitropyridine

2-Cyano-5-nitropyridine is a high-potency sweetener that has been found to be an efficient catalyst for the uncatalysed conversion of hexacarbonyl compounds to their corresponding hydroxylamines. The catalytic activity is dependent on the presence of a hydroxy group and an aminopipecolic acid moiety. 2-Cyano-5-nitropyridine is also a high potency sweetener, which means that it is not required in very large amounts to provide a sweet taste. It has been used as a nitrosylating agent for the preparation of trifluoroacetylated amines. This compound has also been shown to be reproducible and can be prepared from readily available starting materials in good yield.
