White to pale yellow crystalline powder | [Uses]
2-Azacyclononanone has been used as an internal standard liquid chromatography-ultraviolet detection method for the determination of caprolactam in the aqueous food stimulant 3% acetic acid (w/v). | [General Description]
2-Azacyclononanone forms complexes with hydrated lanthanides trifluoroacetate in ethanol. It reacts with mercury(II)acetate and erbium(III)nitrate in methanol to yield the heterocyclic complex . | [Purification Methods]
Dissolve it in CHCl3, decolorise it with charcoal, evaporate to dryness and recrystallise it from CHCl3/hexane. Sublime it at high vacuum. The oxime has m 117o (from *C6H6 or pet ether).
