In the intricate science of aroma and flavor, understanding the chemical foundation of key ingredients is crucial. Isoeugenol (CAS 97-54-1) is a prime example of such a compound, a phenylpropene that serves as a fundamental building block for a wide spectrum of sensory experiences. Its molecular structure dictates its characteristic aroma and its utility in various chemical transformations, making it indispensable for professionals in the flavor and fragrance sectors.

Chemically, Isoeugenol is an isomer of eugenol, differing in the placement of a double bond within its propenyl side chain. This seemingly minor alteration results in a distinct olfactory profile. While eugenol offers a more pungent, medicinal clove aroma, Isoeugenol presents a softer, sweeter, more floral, and spicy fragrance with woody undertones. This nuanced difference makes it highly desirable for applications where a less aggressive, more rounded spicy note is required. Its physical form is typically a pale yellow oily liquid, and its purity, often specified as ≥99.0%, is a critical factor for consistent performance in complex formulations.

The synthesis of Isoeugenol often involves the isomerization of eugenol, typically through alkali treatment at elevated temperatures or via catalytic processes. This chemical transformation allows manufacturers to produce a compound with a specific aromatic signature. Understanding its synthetic pathways can be beneficial for R&D scientists exploring new routes to aromatic chemicals or seeking to optimize production processes.

The primary applications for Isoeugenol leverage its compelling aroma. In perfumery, it is foundational for creating accords that mimic the scent of carnations, and it adds warmth and complexity to oriental, spicy, and floral fragrance compositions. Its excellent substantivity ensures that scents remain detectable for extended periods. For flavorists, Isoeugenol is used to impart warm, spicy notes in a variety of food products, including beverages, baked goods, and savory items, and is particularly noted for its contribution to flavors like ham, nutmeg, and certain fruit profiles.

Beyond its direct use as an aromatic ingredient, Isoeugenol plays a significant role as a chemical precursor. Its conversion into vanillin is a key industrial process, underscoring its importance in the global supply chain for vanilla flavor. This dual functionality—as a sensory ingredient and a synthesis intermediate—amplifies its value for chemical manufacturers. Sourcing high-grade Isoeugenol from a reliable manufacturer ensures that these downstream processes can be carried out efficiently and with consistent product quality.

For B2B buyers, procuring Isoeugenol involves a strategic approach. When seeking to purchase this compound, it is essential to partner with suppliers who can guarantee purity, consistency, and reliable delivery. Manufacturers often provide detailed technical specifications, including CAS numbers, and safety data sheets (SDS) for handling and compliance. Requesting quotes and samples is a standard practice to evaluate the material and establish pricing and delivery terms. The ability to buy Isoeugenol in bulk from a trusted source is vital for maintaining operational continuity.

In conclusion, Isoeugenol (CAS 97-54-1) is a cornerstone ingredient in the flavor and fragrance industries, valued for its unique aroma and its role in chemical synthesis. Its chemical properties, synthesis routes, and diverse applications highlight its significance. For businesses aiming to innovate and excel, a strategic approach to sourcing this versatile aromatic building block is key.
