2-Acetylthiophene (CAS: 88-15-3) is a high-purity heterocyclic ketone that features a distinctive and versatile aroma profile, characterized by pronounced popcorn-like, nutty, roasted, and slightly sulfurous notes with subtle caramel and cereal undertones. This compound belongs to the thiophene family and is widely recognized in the flavor and fragrance industry for its ability to impart warm, toasted, and savory characteristics to various formulations.

With a molecular formula of C₆H₆OS, 2-Acetylthiophene presents as a colorless to pale yellow crystalline solid at room temperature, with a melting point range of 10°C to 12°C. It exhibits excellent solubility in ethanol, propylene glycol, and most organic solvents commonly used in flavor and fragrance applications. The product is manufactured under strict quality control standards to ensure consistent purity, typically exceeding 99%, and reliable batch-to-batch uniformity.

In flavor applications, 2-Acetylthiophene is highly valued for its ability to create authentic roasted, nutty, and popcorn-like profiles. It is extensively used in savory snack seasonings, where it contributes to the characteristic aroma of roasted nuts, such as peanut, hazelnut, and almond. The compound also plays a key role in popcorn flavor formulations, providing the distinctive buttery-roasted character associated with freshly popped corn. Additionally, it finds application in coffee, chocolate, caramel, and cereal-type flavors, adding depth and complexity to both sweet and savory product lines.

Beyond flavor applications, 2-Acetylthiophene serves as a valuable intermediate in pharmaceutical synthesis and organic chemistry. Its thiophene ring structure makes it a useful building block for the preparation of various biologically active compounds, including antimicrobial agents, anti-inflammatory drugs, and other therapeutic molecules. In fragrance compositions, it contributes warm, nutty, and slightly roasted accords that enhance gourmand and oriental-type perfumes.

Each batch undergoes comprehensive quality control testing, including gas chromatography analysis to verify purity, organoleptic evaluation to confirm aroma profile, and physical property testing to ensure compliance with established specifications. The product is manufactured in accordance with applicable industry standards for flavor and fragrance ingredients.
