However, it is occasionally used in pharmaceutical formulations as a flavoring agent for oral medications and supplements to improve palatability for patients. Its fruity aroma can help mask the bitterness or unpleasant taste of certain medicines, making them more tolerable for consumption.
Overall, ethyl undecanoate plays a vital role in enhancing the sensory experience of various consumer products in the commercial and industrial sectors. While its applications in drugs and medications are limited, its ability to improve taste and scent makes it a valuable additive in a range of industries.
⚗️ Chemical & Physical Properties
Ethyl undecanoate is a colorless liquid with a fruity odor, resembling that of ripe peaches or apricots.
The molar mass of Ethyl undecanoate is approximately 200.31 g/mol, with a density of about 0.875 g/cm³. This places it in the range of common food items such as vegetable oil (Molar mass: 784.00 g/mol, Density: 0.920 g/cm³) and vinegar (Molar mass: 60.05 g/mol, Density: 1.01 g/cm³).
Ethyl undecanoate has a melting point of around -22°C and a boiling point of approximately 264°C. These properties differ from common food items like sugar (Melting point: 186°C, Boiling point: 186°C) and salt (Melting point: 801°C, Boiling point: 1465°C).
Ethyl undecanoate is slightly soluble in water, with a viscosity similar to that of coconut oil. This sets it apart from common food items like salt (Insoluble in water, Low viscosity) and sugar (Very soluble in water, Low viscosity).
🏭 Production & Procurement
Ethyl undecanoate is primarily produced through the esterification of undecanoic acid with ethanol. This reaction, typically carried out in the presence of an acid catalyst, results in the formation of Ethyl undecanoate, a clear liquid with a fruity odor commonly used in the fragrance and flavor industries.
In terms of procurement, Ethyl undecanoate can be obtained from chemical suppliers who specialize in the production and distribution of esters. It is often available in bulk quantities, stored in sealed containers to prevent oxidation or contamination. Transportation of Ethyl undecanoate is typically done via tanker trucks or drums, ensuring proper handling and adherence to safety regulations.
Upon arriving at its destination, Ethyl undecanoate is usually stored in a cool, dry area away from direct sunlight to maintain its stability and quality. Proper labeling of containers is essential to ensure the correct identification and handling of the substance. Users of Ethyl undecanoate must adhere to relevant safety guidelines and protocols to prevent accidents or exposure risks.
⚠️ Safety Considerations
Safety considerations for Ethyl undecanoate include its flammability, as it is a highly flammable liquid that should be stored away from heat, sparks, and open flames. In addition, prolonged or repeated exposure may cause skin irritation, and it should be handled with appropriate protective equipment such as gloves, goggles, and a lab coat. Ethyl undecanoate should be used in a well-ventilated area to prevent inhalation of its vapors, and spills should be cleaned up immediately to avoid slipping hazards.
Hazard statements for Ethyl undecanoate include “Causes skin irritation” and “Highly flammable liquid and vapor.” These statements indicate the potential for skin irritation upon contact and the flammability of the substance. It is important to handle Ethyl undecanoate with care to prevent skin irritation and to minimize the risk of fires or explosions.
Precautionary statements for Ethyl undecanoate include “Keep away from heat/sparks/open flames/hot surfaces” and “Wear protective gloves/eye protection/face protection.” These statements emphasize the importance of avoiding ignition sources and using proper protective equipment when handling the substance. It is crucial to follow these precautionary measures to ensure safe use of Ethyl undecanoate and minimize the risk of accidents or injuries.
🔬 Potential Research Directions
One potential research direction for Ethyl undecanoate is its use in the development of new fragrance formulations due to its fruity, floral, and waxy odor profile. Researchers may explore the impact of different concentrations of Ethyl undecanoate on the overall scent profile of a fragrance blend.
Another potential avenue of research is investigating the potential antimicrobial properties of Ethyl undecanoate. Studies could be conducted to assess its effectiveness against a range of bacterial and fungal strains, as well as its potential for use in disinfectant products.
Furthermore, researchers may also explore the environmental impact of Ethyl undecanoate and its biodegradability. Studies could investigate the fate of Ethyl undecanoate in different environmental matrices and assess its potential for bioaccumulation in aquatic and terrestrial ecosystems.
