Description

2-(4-Methyl-5-Thiazolyl)Ethyl Isobutyrate is a high-purity organic ester compound valued for its unique thiazole-based structure, which serves as a critical intermediate and flavor/fragrance component. This compound matters for its ability to impart specific organoleptic characteristics and act as a versatile building block in advanced organic synthesis. It is primarily needed by manufacturers in the flavor and fragrance industry, as well as by pharmaceutical and agrochemical research organizations developing novel active ingredients.

Application

• As a key flavor and fragrance ingredient, imparting unique savory, roasted, or nutty notes to food products and perfumes.
• As a versatile chemical intermediate in the synthesis of more complex pharmaceutical compounds and active ingredients.
• In agrochemical research for the development of novel pesticides or herbicides utilizing the thiazole moiety.
• As a reference standard in analytical laboratories for quality control and method development in flavor and fragrance analysis.
• For use in organic electronic materials research, exploring the properties of thiazole derivatives.
• In the development of specialty polymers and functional materials where specific ester groups are required.

Quality Control

Our 2-(4-Methyl-5-Thiazolyl)Ethyl Isobutyrate is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including chromatography and spectroscopy, to ensure high purity and consistent organoleptic profile suitable for flavor, fragrance, and synthetic applications. Certificates of Analysis (COA) documenting identity, assay, and impurity levels are available upon request to support your quality assurance and regulatory compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). Due to its properties of being easily oxidized and highly volatile, it is recommended to store under an inert atmosphere (e.g., nitrogen) for long-term preservation and to minimize exposure to strong acids and organic solvents. Keep away from heat and open flame.
