C13H18O2 Mol. Wt. 206.28
Chemical name or synonyms: Phenyl Acetic acid Isoamyl ester, Iso Amyl Phenyl Acetate, 3-methylbutyl 2-phenylacetate
Content Isoamyl Phenylacetate: contains not less than 98.0% of isoamyl phenylacetate (C13H18O2)
Description: Isoamyl Phenylacetate is a colorless, transparent liquid having a characteristic odor
Identification:
(1) To 2 ml of Isoamyl Phenylacetate, add 10 ml of ethanolic 10% potassium hydroxide TS, and boil gently with a reflux condenser in a water bath for 1 hour. The characteristic odor disappears, and an odor of isoamyl alcohol is evolved.
(2) To the solution of (1) above, add 10 ml of water, distill, discard 15 ml of the initial distillate, and acidify the remaining distillate with diluted hydrochloric acid. Crystals are deposited. Collect the crystals by filtration, wash with water, and recrystallize from boiling water. The melting point is 76 to 78.
