Description

Ethyl Thiobutyrate is a volatile organic compound valued for its distinctive sulfurous, fruity aroma, which is pivotal in flavor and fragrance engineering. This organosulfur ester is a key intermediate in the synthesis of more complex aroma chemicals and functional materials. It serves the needs of flavor and fragrance manufacturers, agrochemical producers, and research laboratories developing novel sulfur-containing compounds.

Application

• Flavor and Fragrance Industry: A key building block for creating sulfurous, tropical, and fruity notes (e.g., pineapple, passion fruit) in food flavorings and perfumery.
• Agrochemical Synthesis: Serves as a versatile intermediate in the production of pesticides, herbicides, and other active ingredients requiring a thioester moiety.
• Organic Synthesis: Used as a reagent in various chemical transformations, including thioacetal formation and as a source of the thiobutyryl group.
• Research and Development: Employed in academic and industrial R&D for studying reaction mechanisms and developing new synthetic methodologies involving sulfur compounds.
• Specialty Chemicals: A precursor for manufacturing specialty polymers, lubricant additives, and corrosion inhibitors where specific organosulfur functionality is required.

Quality Control

Our Ethyl Thiobutyrate is produced under strict quality management protocols. Every batch undergoes comprehensive analytical testing, including GC and IR spectroscopy, to ensure identity, purity, and consistency. We provide full traceability and Certificates of Analysis (COA) are available for all shipments, confirming compliance with agreed specifications.

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 to prevent evaporation and maintain product integrity. Recommended storage temperature is 2-8°C for long-term stability.
