DEFINITION

Classification: 44/327

Organic azide compound, or organic compound having acyclic nitrogen double bonded to acyclic nitrogen (e.g., diazo compounds, etc.):

(under subclass 300) Compositions which contain organic compounds having acyclic nitrogen double bonded to acyclic nitrogen or organic azide compounds.

(1) Note. The azide group has no single definite structure; it can be represented by different resonance forms, such as: [figure]

The azide group is generally depicted as: [figure]

(2) Note. Organic azide compounds have the azide group attached directly or indirectly, by nonionic bonding, to carbon of an organic compound. See Glossary in the class definition for the definition of "organic compound".

(3) Note. Similarly, organic compounds having acyclic nitrogen double bonded to acyclic nitrogen must have the nitrogens attached directly or indirectly, by nonionic bonding, to carbon of an organic compound.

(4) Note. An example of an ingredient provided for herein is: [figure]
