Description

4-Ethyl-2,5-Dimethyloxazole is a heterocyclic organic compound belonging to the oxazole class, valued for its role as a versatile flavor and fragrance intermediate. This compound is particularly significant for imparting roasted, nutty, or green sensory notes, making it a key building block in the creation of complex aroma profiles. It is primarily needed by manufacturers in the flavor and fragrance, food ingredient, and fine chemical synthesis industries.

Application

• Flavor & Fragrance Industry: A key intermediate for synthesizing complex aroma chemicals that replicate roasted coffee, nutty, cocoa, or green vegetable notes.
• Food Ingredient Manufacturing: Used in the development of savory flavorings, reaction flavors (e.g., meat, bread), and natural-identical flavor compounds.
• Fine Chemical Synthesis: Serves as a valuable heterocyclic building block for pharmaceutical research and the synthesis of more complex organic molecules.
• Agrochemical Intermediates: Potential use in the research and development of novel active ingredients and performance chemicals.
• Research & Development: Utilized in academic and industrial R&D for studying heterocyclic chemistry and developing new synthetic pathways.

Quality Control

Our 4-Ethyl-2,5-Dimethyloxazole is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including GC or HPLC analysis, to ensure high purity and consistent performance. Certificates of Analysis (COA) detailing identity, purity, and specific impurity profiles are available upon request to support your quality assurance protocols.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials. Due to its highly volatile nature, ensure containers are kept tightly sealed when not in use. Recommended storage temperature is 2-8°C for extended stability, though short-term storage at controlled room temperature (15-25°C) is acceptable.
