In the vast landscape of specialty chemicals, Isoeugenol (CAS 97-54-1) holds a significant position, particularly within the flavor and fragrance sectors. This aromatic compound, known for its distinctive spicy and clove-like aroma, is a critical ingredient for product development and also serves as a valuable intermediate in chemical synthesis. For procurement managers, R&D scientists, and product formulators, a comprehensive understanding of Isoeugenol's properties, applications, and sourcing is essential.

Physico-Chemical Profile of Isoeugenol

Isoeugenol typically presents as a pale yellow, oily liquid with a characteristic sweet, spicy, and warm aroma often associated with cloves. Its chemical structure, C10H12O2, with a molecular weight of 164.20, features a phenylpropene backbone with methoxy and hydroxyl groups, contributing to its reactivity and aromatic qualities. Key physical properties include a density around 1.08 g/mL and a high boiling point (around 266°C), indicating its relative low volatility. Its refractive index typically falls between 1.572 and 1.578. These characteristics are vital for formulators when considering compatibility and application methods. Understanding its isomerism, particularly the cis and trans forms, is also important as their relative proportions can subtly influence the final aroma profile.

Key Applications Across Industries

The versatility of Isoeugenol is evident in its wide range of applications:

  • Flavor Industry: It is extensively used to impart spicy notes in food products, including savory items like processed meats and seasonings, as well as in confectionery, baked goods, and beverages. Its profile complements fruits like raspberries and peaches, and spices like nutmeg and cinnamon.
  • Fragrance Industry: Isoeugenol is a foundational ingredient for creating floral fragrances, especially carnation notes, and adds warmth and complexity to oriental, woody, and spicy perfume compositions. It is also used in cosmetics, soaps, and detergents for its scent.
  • Chemical Synthesis: A primary use is as a precursor for vanillin production, a globally significant flavor compound. It also serves as a starting material for other derivatives like dihydrogenol, making it a strategic choice for chemical manufacturers.
  • Other Uses: Historically, it has seen application in dental materials and is being explored for its potential antimicrobial and antioxidant properties.

Sourcing and Procurement Considerations

For businesses looking to procure Isoeugenol, the focus must be on quality, consistency, and a reliable supply chain. Purchasing from reputable manufacturers, often based in China, ensures access to high-purity material (typically ≥99.0% assay). Buyers should always request detailed specifications, including CAS number (97-54-1), and relevant safety data sheets (SDS). Obtaining quotes from multiple suppliers is advisable to compare pricing, MOQs, and lead times. Establishing a relationship with a trusted supplier is crucial for long-term success, ensuring consistent quality and timely delivery for your production needs.

Safety and Handling

While valuable, Isoeugenol requires careful handling. It is classified as a skin irritant and sensitizer, and can be harmful if swallowed. Adherence to recommended safety protocols, including wearing appropriate personal protective equipment (gloves, eye protection) and working in well-ventilated areas, is essential. Consulting the SDS is the first step in ensuring safe usage and compliance with regulatory standards.

In conclusion, Isoeugenol (CAS 97-54-1) is a multifaceted compound indispensable to the flavor, fragrance, and chemical synthesis industries. Its unique aromatic profile, chemical reactivity, and wide-ranging applications make it a strategic ingredient for any forward-thinking business. Effective sourcing and safe handling are key to unlocking its full potential.
