Propyl Hexanoate, identified by CAS number 626-77-7, is more than just a pleasant aroma; it's a molecule with a specific set of chemical properties that dictate its broad utility. Understanding these characteristics is fundamental for anyone looking to effectively utilize this ester, whether for its flavor, fragrance, or industrial applications. As a leading chemical manufacturer, we highlight these key attributes of Propyl Hexanoate.

At its core, Propyl Hexanoate is an ester formed from hexanoic acid and propanol. This ester linkage (R-COO-R') is responsible for its relatively stable yet reactive nature. Its molecular formula, C9H18O2, and molecular weight of approximately 158.24 g/mol, are standard identifiers for this compound. Physically, it presents as a clear, colorless liquid, a visual characteristic that aligns with its high purity, often exceeding 98%.

The defining feature of Propyl Hexanoate, from an application standpoint, is its olfactory profile – a sweet, fruity scent often likened to pineapple. This characteristic is due to the specific arrangement of its carbon chain and ester group, which interact with olfactory receptors to produce this distinct aroma. This makes it a sought-after component when you buy Propyl Hexanoate for use in perfumes, cosmetics, and food flavorings.

Chemically, Propyl Hexanoate exhibits good solubility in organic solvents such as ethanol and ether. This is a common trait for esters with moderate hydrocarbon chains, enabling it to be easily incorporated into various formulations. However, its solubility in water is limited due to the hydrophobic nature of the hexyl chain, a factor that influences its application in aqueous systems.

Its boiling point, around 186-188°C, and flash point, approximately 68°C (closed cup), are important safety and handling parameters. These properties indicate its moderate volatility and flammability, requiring appropriate storage and handling procedures, a standard practice for chemical suppliers. For industrial applications, its role as a solvent and plasticizer is linked to its ability to interact with and modify the properties of other materials.

The consistent chemical properties of Propyl Hexanoate, such as its aroma, solubility, and stability, are what make it a reliable choice for manufacturers. When you choose to buy Propyl Hexanoate from a reputable chemical supplier in China, you are investing in a well-understood and highly effective chemical ingredient.
