2-AZACYCLONONANONE Usage And Synthesis

Chemical Properties

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).
