In the intricate world of aroma chemicals, precision and understanding are key. For professionals in the fragrance and flavor industry, identifying and sourcing high-quality ingredients is a continuous pursuit. One such pivotal compound is identified by its CAS number 28940-11-6, widely recognized as Watermelon Ketone, or its proprietary name Calone.

This synthetic ingredient, chemically designated as 8-methyl-1,5-benzodioxepin-3-one, is celebrated for its distinctive contribution to the olfactory landscape. Its primary characteristic is a powerful marine and ozonic scent, often described as reminiscent of sea breeze, with underlying notes of melon and a subtle floral undertone. This unique profile has made it a cornerstone in the creation of aquatic, marine, and oceanic fragrances since its widespread adoption in the 1990s.

For R&D scientists and procurement specialists, understanding the technical specifications of CAS 28940-11-6 is crucial. Key parameters include its appearance (typically a white powder or pale yellow liquid), purity (often exceeding 99.0% via HPLC), and its organoleptic properties—its scent strength, type, and substantivity. These details are vital when evaluating potential suppliers and ensuring the ingredient meets the stringent requirements of fine perfumery.

When sourcing this essential aroma chemical, identifying reliable manufacturers and suppliers is a top priority. Buyers often look for suppliers in regions known for chemical production, such as China, which offers competitive pricing and large-scale manufacturing capabilities. A supplier's ability to provide detailed product documentation, including safety data sheets (SDS) and certificates of analysis (CoA), is also a critical factor. Furthermore, the availability of samples for evaluation and clear communication regarding order placement, payment terms, and delivery schedules are hallmarks of a trustworthy partner.

The application of Watermelon Ketone is not limited to fine fragrances. It also serves as an analytical standard and can be used in olfactory research. Its unique scent profile allows perfumers to create a wide range of effects, from the refreshing scent of a sea spray to the breezy freshness of an open-air landscape.

For those in the market to buy CAS 28940-11-6, exploring options from established chemical manufacturers in China can provide a cost-effective and reliable solution. By focusing on quality, consistency, and transparent communication, procurement teams can secure a steady supply of this indispensable marine aroma chemical, empowering them to create truly captivating fragrances.
