Watermelon Ketone (Calone) is being classified for its dual-use in both the Pharmaceutical and Fragrance industries. Calone 1951: The Gold Standard for Aquatic and Marine Synthesis. Calone 1951 is an ultra-pure crystalline intermediate (≥99%) engineered for industries where scent precision and chemical stability are non-negotiable. While legendary in the fragrance industry for creating the "sea breeze" and "watermelon" accords of iconic aquatic perfumes, its unique benzodioxepinone structure also serves as a specialised scaffold in medicinal chemistry research. Whether formulating a high-end luxury fragrance or exploring the bioactivity of oxygen-heterocyclic compounds, our grade provides the olfactory clarity and isomeric purity required for world-class results. We are a globally established Pharmaceutical AND Aroma chemical supplier, along with a broad portfolio of various ‘Intermediates’ worldwide through comprehensive regulatory documentation (CoA), traceability, and consistent global supply capabilities, ensuring reliable lead times and quality assurance across all grades.
