Description
2-Methylbutyl isovalerate, also known as 2-Methylbutyl-3-methylbutanoate, is a colorless liquid with a herbaceous, fruity, and somewhat earthy fragrance. It has a sweet, herbaceous, and fruity flavor, and can be prepared by direct esterification of 2-methylbutanol with isovaleric acid. It is soluble in alcohol and fixed oils but insoluble in water.
Uses
Used in Flavor Industry:
2-Methylbutyl isovalerate is used as a flavoring agent for its herbaceous, fruity, and somewhat earthy fragrance, as well as its sweet, herbaceous, and fruity flavor. It is commonly used to impart a fruity, estery taste with a berry-apple and tutti-frutti nuance to various products.
Used in Food Industry:
2-Methylbutyl isovalerate is used as a food additive for its ability to enhance the flavor of various food products. It has a taste threshold value of 5 to 15 ppm, which allows it to impart a fruity, estery taste with a berry-apple and tutti-frutti nuance to foods.
Used in Fragrance Industry:
2-Methylbutyl isovalerate is used as a fragrance ingredient for its herbaceous, fruity, and somewhat earthy fragrance. It can be used to add depth and complexity to perfumes and other scented products.
Occurrence:
2-Methylbutyl isovalerate has been reported to be found in various natural sources, including tomato, peppermint and oil, Scotch spearmint oils, cheddar cheese, hop oil, sherry, quince, jackfruit, and whiskey.
Preparation
By direct esterification of 2-methylbutanol with isovaleric acid.
Check Digit Verification of cas no
The CAS Registry Mumber 2445-77-4 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,4,4 and 5 respectively; the second part has 2 digits, 7 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 2445-77:
(6*2)+(5*4)+(4*4)+(3*5)+(2*7)+(1*7)=84
84 % 10 = 4
So 2445-77-4 is a valid CAS Registry Number.

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.
