Anethole, bearing the CAS number 4180-23-8, is a compound whose chemical identity is intrinsically linked to its widespread use in various industries. Its molecular formula, C10H12O, and a molar mass of approximately 148.2017 g/mol, provide the fundamental building blocks for its distinctive sensory attributes and functional properties.

One of the most significant chemical properties of anethole is its stereoisomerism. It exists primarily as trans-anethole and cis-anethole, with the trans isomer being the more commercially dominant and preferred form due to its stronger and sweeter aroma profile. The anethole chemical properties, such as its boiling point of 234-237°C and a melting point of 20-21°C, classify it as a liquid at room temperature, often appearing as a pale yellow substance. Its relatively low solubility in water but high solubility in ethanol is what famously causes the 'ouzo effect' in certain alcoholic beverages, a phenomenon of spontaneous microemulsion formation.

The purity of anethole is critical for its applications. Typically supplied at a purity of 99%, this ensures consistency and effectiveness, particularly in the sensitive fragrance and flavor sectors. The industry actively seeks out high-purity synthetic anethole to guarantee predictable results in formulations. Understanding the nuances of these anethole chemical properties allows manufacturers to precisely incorporate it into their products.

These chemical characteristics directly influence its adoption. As a key component in anethole in fragrance, its aroma is described as sweet, floral, and herbaceous, with a prominent anise or licorice note. This makes it invaluable for creating popular scent profiles. In the flavor industry, its taste complements confectionery, beverages, and oral care products, contributing to its broad appeal.

The exploration of anethole CAS number 4180-23-8 also leads to understanding its sourcing. While naturally found in anise and fennel, commercial anethole is largely derived as a by-product of turpentine processing, a testament to efficient chemical engineering. This availability, coupled with its desirable anethole chemical properties, solidifies its position as a staple aroma chemical.

For businesses looking to harness the power of this compound, knowing the specific anethole chemical properties is paramount. Whether for its aromatic qualities, its flavor contribution, or its functional aspects like antimicrobial activity, anethole remains a compound of significant industrial importance.
