4-BUTOXYANILINE Chemical Properties,Usage,Production

Chemical Properties

CLEAR DARK BROWN LIQUID

Uses

4-Butoxyaniline was used in the preparation of:

• bis-4-butoxyphenyl-4,4′-(2,2′-bipyridyl)carbamide
• 1-(4-butoxyphenyl)-3-(6-methyl-3-oxo-2-phenyl-2,3-dihydropyridazin-4-yl)urea

General Description

4-Butoxyaniline undergoes low-pressure hydrogenation in the presence of rhodium on alumina to yield 4-butoxycyclohexylamine.
