Usage

General Description

Amyl Isobutyrate, also known as Isobutyric acid amyl ester, is a chemical compound used often as a flavoring agent due to its fruity odor. It is most commonly used in foods, beverages, and confectioneries. Other uses include as a solvent for chemicals and as a synthetic fruit flavoring in baked goods, gelatins, candies, fats, oils, and beverages. This chemical compound has a clear, colorless liquid appearance and is insoluble in water but has good solubility in alcohol and oils. Despite its broad usage, Amyl Isobutyrate can be harmful if swallowed or inhaled and can cause skin allergies.

Nematicidal activity of natural ester compounds and their analogues against pine wood nematode, bursaphelenchus xylophilus

In this study, we evaluated the nematicidal activity of natural ester compounds against the pine wood nematode, Bursaphelenchus xylophilus, to identify candidates for the development of novel, safe nematicides. We also tested the nematicidal activity of synthesized analogues of these ester compounds to determine the structure-activity relationship. Among 28 ester compounds tested, isobutyl 2-methylbutanoate, 3-methylbutyl 2-methylbutanoate, 3-methylbutyl tiglate, 3-methyl-2-butenyl 2- methylbutanoate, and pentyl 2-methylbutanoate showed strong nematicidal activity against the pine wood nematode at a 1 mg/ mL concentration. The other ester compounds showed weak nematicidal activity. The LC50 values of 3-methylbutyl tiglate, isobutyl 2-methylbutanoate, 3-methylbutyl 2-methylbutanoate, 3-methyl-2-butenyl 2-methylbutanoate, and pentyl 2- methylbutanoate were 0.0218, 0.0284, 0.0326, 0.0402, and 0.0480 mg/mL, respectively. The ester compounds described herein merit further study as potential nematicides for pine wood nematode control.
