Overview
Decanoate, also known as decyl ester or caprate, is an ester derived from decanoic acid. It is widely used in various industries due to its stability and mild properties. In pharmaceuticals, it serves as an excipient or active ingredient in prolonged-release formulations. The food industry utilizes it as a flavoring agent or preservative, while industrial applications include its use in lubricants and plasticizers. Decanoate is synthesized through esterification reactions involving decanoic acid and alcohols. Its versatility and relatively low toxicity make it a preferred choice in formulations requiring slow release or enhanced stability. Regulatory bodies often approve its use in food and pharmaceuticals, provided it meets purity standards.
Physical and Chemical Properties
Decanoate is a colorless to pale yellow liquid with a mild odor. It has a molecular weight of 172.26 g/mol and a density of approximately 0.89 g/cm³. The compound is insoluble in water but dissolves readily in organic solvents such as ethanol and ether. Its boiling point ranges between 270-280°C, depending on purity and atmospheric conditions. Chemically, decanoate is stable under normal conditions but may degrade under extreme heat or prolonged exposure to strong acids or bases. Its ester linkage provides moderate reactivity, making it suitable for controlled-release applications. The compound’s low volatility and high boiling point contribute to its utility in high-temperature industrial processes.
Main Applications
In the pharmaceutical industry, decanoate is commonly used in depot injections, where it slows the release of active ingredients like antipsychotics or hormones. This property enhances patient compliance by reducing dosing frequency. In food production, it acts as a flavor enhancer or preservative, particularly in dairy and baked goods. Industrial applications include its use as a lubricant additive or plasticizer in polymers. Its ability to improve viscosity and reduce friction makes it valuable in machinery maintenance. Additionally, decanoate is explored in cosmetic formulations for its emollient properties, though this use is less widespread compared to other esters.
Safety and Storage
Decanoate is generally considered low-toxicity, but precautions are necessary to avoid skin contact or inhalation. Personal protective equipment (PPE), such as gloves and goggles, should be worn during handling. In case of exposure, rinse affected areas with water and seek medical advice if irritation persists. Storage recommendations include keeping the compound in a cool, dry place away from direct sunlight and oxidizing agents. Containers should be tightly sealed to prevent contamination or evaporation. Bulk storage requires inert conditions to maintain stability over long periods. Always refer to the material safety data sheet (MSDS) for specific guidelines.
B2B Procurement Guide
When procuring decanoate, prioritize suppliers with certifications like ISO or GMP, especially for pharmaceutical or food-grade applications. Request certificates of analysis (CoA) to verify purity, which typically ranges from 95% to 99%. Price varies based on quantity and purity, with bulk purchases often qualifying for discounts. Logistics considerations include ensuring proper packaging to prevent leaks or degradation during transit. For international shipments, confirm compliance with regional regulations, such as REACH in the EU or FDA in the US. Establish long-term contracts with reliable suppliers to secure consistent quality and pricing.
