1-Heptadecanol, identified by CAS number 1454-85-9, is a saturated fatty alcohol with a molecular formula of C17H36O. This compound is characterized by its long, unbranched carbon chain of seventeen atoms, capped by a primary hydroxyl (-OH) group. This structural feature dictates its chemical behavior and physical properties, making it a valuable compound in numerous industrial and scientific applications. Understanding the fundamental chemical properties of 1-Heptadecanol is key to appreciating its diverse utility.

Physically, 1-Heptadecanol typically presents as a white crystalline powder. Its melting point is around 53-56 °C, classifying it as a solid at room temperature. While sparingly soluble in water, it exhibits good solubility in common organic solvents such as methanol, ethanol, and chlorinated hydrocarbons. This solubility profile is a direct consequence of its long hydrophobic carbon chain, which dominates its interaction with nonpolar solvents. The hydroxyl group, however, allows for some degree of interaction with polar solvents and enables participation in hydrogen bonding.

Chemically, the hydroxyl group in 1-Heptadecanol is the primary site of reactivity. It readily undergoes esterification reactions with carboxylic acids or their derivatives to form fatty acid esters. These esters are widely used in cosmetics as emollients, providing a smooth skin feel and reducing moisture loss. They also find applications as lubricants and plasticizers. The alcohol can also be converted into ethers, halides, or oxidized to the corresponding aldehyde or carboxylic acid, demonstrating its utility as a versatile intermediate in organic synthesis. Many researchers investigate the 1-Heptadecanol chemical properties to unlock new applications.

The long alkyl chain of 1-Heptadecanol contributes to its surface-active properties when incorporated into surfactant molecules. These surfactants are essential in detergents, emulsifiers, and foaming agents across many industries. In the pharmaceutical sector, 1-Heptadecanol itself can serve as an excipient, aiding in drug formulation due to its emollient and stabilizing effects. Its low volatility and chemical stability further enhance its suitability for various applications, from cosmetic formulations to industrial lubricants. The consistent availability of high-purity 1-Heptadecanol from trusted 1-Heptadecanol suppliers ensures its continued relevance in these fields.
