Description
2,4,5-Trimethyl-3-oxazoline is an organic compound characterized by its yellow-orange liquid appearance and a powerful, musty, nut-like odor. It is soluble in alcohol, propylene glycol, and water, but insoluble in fixed oils. 2,4,5-TRIMETHYL-3-OXAZOLINE is known for its characteristic meat aroma, making it a valuable ingredient in the food industry.
Uses
Used in Flavor Industry:
2,4,5-Trimethyl-3-oxazoline is used as a flavor enhancer for its meaty aroma, particularly in the fish industry. It helps to improve the taste and overall sensory experience of various food products.
Used in Food Additives:
As a food additive, 2,4,5-Trimethyl-3-oxazoline contributes to the musty, nutty, cocoa, brown, vegetative, and bready taste characteristics at a concentration of 10 ppm, with a slight bitter nuance. It is commonly found in boiled, cooked, and heated beef, canned beef stew, fried chicken, and roasted peanut, enhancing the flavor profile of these dishes.
Chemical Properties:
2,4,5-Trimethyl-δ-3-oxazoline has a powerful, musty, slight green, wood, nut-like odor, which makes it an essential component in the creation of artificial flavors and fragrances that mimic the natural aroma of cooked meats and other food products.
Safety Profile
When heated to
decomposition emits toxic fumes of NOx.
Check Digit Verification of cas no
The CAS Registry Mumber 22694-96-8 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,2,6,9 and 4 respectively; the second part has 2 digits, 9 and 6 respectively.
Calculate Digit Verification of CAS Registry Number 22694-96:
(7*2)+(6*2)+(5*6)+(4*9)+(3*4)+(2*9)+(1*6)=128
128 % 10 = 8
So 22694-96-8 is a valid CAS Registry Number.

Mechanistic Studies of 2-(1-Hydroxyethyl)-2,4,5-trimethyl-3-oxazoline Formation under Low Temperature in 3-Hydroxy-2-butanone/Ammonium Acetate Model Systems

Volatile compounds formed from the reaction of 3-hydroxy-2-butanone/ammonium acetate at 25, 55 and 85 °C were investigated. Six compounds were characterized by gas chromatography - mass spectrometry (EI and CI). Among the volatile compounds identified, an interesting intermediate compound, 2-(1-hydroxyethyl)-2,4,5-trimethyl-3-oxazoline, was found. 15N-Labeled ammonium acetate was used to confirm the structure of 2-(1-hydroxyethyl)-2,4,5-trimethyl-3-oxazoline. The formation pathway of these volatile compounds was proposed. In these model systems, 2-(1-hydroxyethyl)-2,4,5-trimethyl-3-oxazoline was formed at the reaction temperature below 25 °C. On the other hand, tetramethylpyrazine was the major component when the reaction temperature was higher than 85 °C. The amounts of 2-(1-hydroxyethyl)-2,4,5-trimethyl-3-oxazoline and tetramethylpyrazine increased linearly with the increasing heating time at 55 °C. Protic solvents did not promote 2-(1-hydroxyethyl)-2,4,5-trimethyl-3-oxazoline formation but did favor the formation of tetramethylpyrazine. A kinetic study of 2-(1-hydroxyethyl)-2,4,5-trimethyl-3-oxazoline formation was also performed, and the activation energy was found to be 16.5 kcal/mol.
