2-Ethyl-2-oxazoline oxazolines towards ring-opening by chloride ions during protonation of the imine nitrogen. The direct reaction of propanoyl chloride with 2-chloroethylamine hydrochloride in the presence of triethylamine avoids the formation of water. Propanal reacts with 2-aminoethanol in "t"-butanol to 2-ethyl-2-oxazoline in the presence of the iodinating reagent 1,3-diiodo-5,5-dimethylhydantoin (DIH) and potassium carbonate. 2-Ethyl-2-oxazoline is a readily water-soluble, colorless liquid which is also soluble in a variety of organic solvents and possesses an amine-like smell. Aqueous solutions react alkaline. The compound is stable in alkaline but hydrolyses under acid action. In anhydrous form, 2-ethyl-2-oxazoline is mostly used as a monomer. The cationic
Ethyl butylacetylaminopropionate a derivative of beta-alanine. The EPA has classified ethyl butylacetylaminopropionate as a biochemical substance (biopesticide) based on the fact that it is "functionally identical" to beta alanine. Ethyl butylacetylaminopropionate Ethyl butylacetylaminopropionate (trade name IR3535) is an insect repellent. As ethyl butylacetylaminopropionate is solely a repellent, it has no killing action and does not give rise to selection pressure or development of resistance. It is a colorless and almost odorless oil and is intended to be applied to the skin of humans and animals. It has a broad efficacy against various insects like mosquitoes, ticks, lice, and other bugs. Ethyl butylacetylaminopropionate
