Containing nitrogen or nitrogenous compounds; fixed or combined with azote (nitrogen).
From 'azote' (nitrogen) + '-ed' (adjective suffix), created in the late 18th century to describe substances that contained or had incorporated nitrogen into their composition.
An 'azoted substance' is really a nitrogenous compound, but the obsolete term appears in historical chemistry texts and reminds us that scientists had to find ways to describe 'nitrogenated' before settling on modern terminology.
