💡 Commercial Applications
Octadecanal, also known as stearyl aldehyde, is commonly used in the commercial and industrial sectors for various applications. It is widely used in the production of perfumes, soaps, and cosmetics due to its pleasant scent and its ability to act as a fragrance fixative. Additionally, octadecanal is used in the manufacturing of plasticizers, lubricants, and surfactants, making it a versatile compound in various industries.
In the realm of drug and medication applications, octadecanal has shown promise as a potential therapeutic agent. Research has suggested that octadecanal possesses anti-inflammatory and anti-cancer properties, making it a candidate for the development of new pharmaceutical drugs. Furthermore, octadecanal has been studied for its potential use in drug delivery systems, where it can help improve the stability and efficacy of medications targeted for specific medical conditions.
⚗️ Chemical & Physical Properties
Octadecanal is a white solid compound with a waxy appearance and a pleasant odor similar to that of jasmine flowers.
With a molar mass of approximately 284.48 g/mol and a density of 0.826 g/cm³, Octadecanal is relatively heavier than common household items like water (molar mass of 18.015 g/mol, density of 1 g/cm³) and air (molar mass of 28.97 g/mol, density of 0.0012 g/cm³).
Octadecanal has a melting point of around 59°C and a boiling point of approximately 340°C. These values are significantly higher than those of water (melting point of 0°C, boiling point of 100°C) and common cooking oils (melting point typically below 0°C, boiling point below 200°C).
Octadecanal is practically insoluble in water due to its non-polar nature, and it exhibits a relatively high viscosity compared to common household liquids like water and alcohol. The low solubility in water and elevated viscosity make Octadecanal less miscible and more resistant to flow compared to these common household items.
🏭 Production & Procurement
Octadecanal, also known as stearyl aldehyde, is primarily produced through the oxidation of the corresponding alcohol, octadecanol. This process involves the use of oxidizing agents such as potassium permanganate or chromic acid, leading to the formation of Octadecanal as a result of the cleavage of a carbon-carbon bond within the alcohol molecule.
In terms of procurement, Octadecanal can be obtained from various chemical suppliers or manufacturers that specialize in producing aldehydes. It is typically transported in liquid form, often packaged in drums or tanks for safe and efficient handling during transit. Additionally, Octadecanal can also be synthesized in laboratory settings for research purposes, requiring careful attention to safety protocols and proper handling of hazardous materials.
⚠️ Safety Considerations
Safety considerations for Octadecanal, also known as Stearaldehyde, should be taken seriously due to its potential hazards. This substance may cause skin and eye irritation upon contact, and inhalation of its vapors may result in respiratory irritation. It is important to handle Octadecanal in a well-ventilated area and wear appropriate personal protective equipment, such as gloves and goggles, to minimize the risk of exposure.
In terms of pharmacology, Octadecanal is a long-chain aldehyde commonly used in various industries, including the cosmetic and fragrance industries. It has been found to exhibit antibacterial properties and is often used as a flavoring agent in food products. Additionally, Octadecanal has been studied for its potential to induce apoptosis in cancer cells, making it a subject of interest in cancer research.
The hazard statements for Octadecanal include “Causes skin irritation” and “Causes serious eye irritation.” It is also classified as harmful if swallowed and may cause respiratory irritation. It is important to handle this substance with caution and follow proper safety protocols to avoid potential health risks associated with Octadecanal exposure.
Precautionary statements for handling Octadecanal include wearing protective gloves and eye protection, as well as ensuring adequate ventilation in the working area. In case of skin irritation or contact with eyes, it is advised to wash the affected area thoroughly with water and seek medical attention if necessary. It is also recommended to store Octadecanal in a cool, dry place away from sources of ignition to prevent potential hazards.
