Overview
Nonanedioic acid dimethyl ester, also known as dimethyl azelate, is an organic compound with the molecular formula C11H20O4. It is commonly used as a plasticizer in polymer production due to its ability to improve flexibility and durability. This ester is also employed as an intermediate in the synthesis of fragrances, lubricants, and specialty chemicals. The compound is characterized by its high boiling point and low volatility, making it suitable for applications requiring thermal stability. Its compatibility with a wide range of polymers enhances its utility in industrial processes.
Physical and Chemical Properties
Nonanedioic acid dimethyl ester is a colorless to pale yellow liquid with a density of approximately 1.01 g/cm³. It has a boiling point range of 280-290°C and is soluble in most organic solvents, though it is insoluble in water. These properties make it ideal for use in high-temperature applications and formulations requiring organic solubility. The ester exhibits low volatility and good chemical stability, which contribute to its effectiveness as a plasticizer. Its molecular weight of 216.28 g/mol and ester functional groups allow it to interact favorably with various polymer matrices.
Main Applications
The primary use of nonanedioic acid dimethyl ester is as a plasticizer in the production of flexible polymers, such as PVC and polyurethanes. It enhances the flexibility, elongation, and durability of these materials, making them suitable for applications like cables, films, and coatings. Additionally, this compound serves as an intermediate in the synthesis of fragrances, lubricants, and other specialty chemicals. Its high boiling point and thermal stability make it a valuable component in high-performance lubricants and heat-resistant formulations.
Safety and Storage
Nonanedioic acid dimethyl ester should be handled with care to avoid inhalation, ingestion, or skin contact. Personal protective equipment (PPE), including gloves and goggles, is recommended when working with this chemical. Adequate ventilation should be maintained to minimize exposure to vapors. Storage conditions should include a cool, dry, and well-ventilated area away from direct sunlight and ignition sources. The compound should be kept in tightly sealed containers to prevent contamination and degradation. In case of spillage, absorb with inert material and dispose of according to local regulations.
B2B Procurement Guide
When procuring nonanedioic acid dimethyl ester, industrial buyers should verify the CAS number (124-70-9) to ensure product authenticity. Purity requirements should be clearly specified, as they can impact the compound's performance in specific applications. Suppliers should provide certifications and technical data sheets to confirm quality and compliance with industry standards. Buyers should also consider the scale of procurement, as bulk purchases may offer cost advantages. Establishing long-term relationships with reputable suppliers can ensure consistent quality and reliable supply chains. Additionally, inquire about packaging options and transportation logistics to optimize handling and storage.
