Understanding the chemical underpinnings of flavor and fragrance ingredients is crucial for manufacturers aiming to innovate and produce high-quality products. Gamma-Nonalactone (CAS 104-61-0), commonly known as Aldehyde C-18, is a fascinating gamma-lactone with a significant role in creating desirable scents and tastes. As a dedicated manufacturer and supplier, we aim to provide insights into the chemical nature of this important compound.

Gamma-Nonalactone is a cyclic ester with the chemical formula C9H16O2 and a molecular weight of 156.22 g/mol. Its structure features a six-membered ring containing an ester linkage, derived from nonanoic acid. This lactonic structure is key to its characteristic aroma – a rich, creamy, and sweet coconut scent with subtle milky and fruity undertones. While often called Aldehyde C-18, it's important to note its chemical classification as a lactone, which dictates its reactivity and olfactory properties.

From a chemical perspective, Gamma-Nonalactone exhibits good stability, particularly in acidic conditions. This characteristic makes it a reliable component in formulations that may involve acidic ingredients or processing steps, such as certain fruit-based flavors or cosmetic products. However, it is noted to be unstable in alkaline environments, a factor that formulators must consider. Its solubility in fixed oils, mineral oil, and propylene glycol further enhances its versatility for various applications.

The synthesis of Gamma-Nonalactone can be achieved through several chemical routes. Common methods include the lactonization of nonenoic acid, or via reactions involving methyl acrylate and hexanol in the presence of specific catalysts. These industrial processes are optimized for scalability and cost-effectiveness, allowing for the production of high-purity Gamma-Nonalactone required by the flavor and fragrance industries. As a manufacturer, our focus is on employing efficient synthesis pathways to ensure consistent quality.

The physical properties of Gamma-Nonalactone are also noteworthy. It is typically a colorless to pale yellow liquid at room temperature, with a boiling point of around 121-122 °C at 6 mm Hg. Its refractive index and density are also key parameters that quality control departments monitor to ensure product consistency. When manufacturers choose to buy Gamma-Nonalactone, they are investing in a compound with well-defined chemical and physical attributes that contribute to predictable product performance.

In essence, Gamma-Nonalactone is a chemically robust and olfactorily valuable lactone. Its structure, stability, and synthesis methods underscore why it remains a staple ingredient for creating captivating coconut and creamy notes in a myriad of products. For businesses seeking this crucial component, understanding its chemical profile is the first step towards successful formulation and innovation.
