NINGBO INNO PHARMCHEM CO.,LTD. is proud to be at the forefront of supplying critical ingredients for the global fragrance market. Today, we explore the intricate science behind Watermelon Ketone (CAS 28940-11-6), a compound celebrated for its characteristic marine and fruity scent. Understanding its chemical structure, synthesis, and application is key to harnessing its full potential in perfume creation.

Chemically identified as 7-methyl-2H-1,5-benzodioxepin-3(4H)-one, Watermelon Ketone is a synthetic organic compound. Its molecular formula, C10H10O3, and molar mass of 178.18 g/mol, describe a molecule that has captivated perfumers for decades. Typically appearing as a white to off-white powder or crystal, it possesses a melting point range of 37-41 °C, indicating its solid state at room temperature. The odor profile is consistently described as fresh, watery, clean melon, green, marine, and ozonic, with phenolic undertones – a complex bouquet that makes it indispensable for specific fragrance types.

The synthesis of Watermelon Ketone involves precise chemical reactions. Common methods often start with the etherification of 4-methylcatechol, followed by a Dieckmann condensation and subsequent hydrolysis and decarboxylation. This multi-step process ensures the high purity required for its application in perfumery. The availability of this compound with assay levels of 99% or higher, as supplied by NINGBO INNO PHARMCHEM CO.,LTD., guarantees consistent performance and quality in formulations.

The applications of Watermelon Ketone are diverse, primarily centering on its role as a 'marine' aroma chemical.
