In the realm of fine chemicals and industrial intermediates, certain compounds emerge as cornerstone materials due to their versatility and essential roles in manufacturing processes. Monomethyl Sebacate, identified by its CAS number 818-88-2, is precisely such a compound. This article delves into its chemical properties, explores its significant industrial applications, and offers insights into navigating its global supply chain for procurement managers and R&D professionals.

Monomethyl Sebacate is a chemical compound that typically presents as a white powder. Its molecular formula is C11H20O4, and it possesses a molecular weight of approximately 216.28 g/mol. The compound's key physical characteristics include a melting point between 41-44°C and a boiling point of 168-170°C at 3 mmHg, indicating its thermal behavior under different conditions. It is essentially a monoester formed from sebacic acid and methanol, making it a derivative of a long-chain dicarboxylic acid. This structure is fundamental to its reactivity and its suitability for various chemical transformations and applications.

The industrial applications of Monomethyl Sebacate are diverse and critical. One of its primary uses is as an intermediate in the synthesis of polyesters. Polyesters are a broad class of polymers that play a significant role in many industries, from textiles and packaging to automotive components and coatings. As a difunctional molecule (containing both a carboxylic acid group and an ester group), Monomethyl Sebacate can participate in polymerization reactions, contributing specific chain characteristics to the final polyester. For manufacturers aiming to produce specialized polyesters with tailored properties, sourcing high-purity Monomethyl Sebacate is key. When considering a purchase, looking for suppliers that offer this chemical with a CAS number of 818-88-2 and a high purity level (e.g., ≥98.0%) ensures reliable performance in polymerization processes.

Another significant application is its role as a plasticizer. Plasticizers are crucial additives that enhance the flexibility, durability, and workability of polymers. By reducing the glass transition temperature of polymers, Monomethyl Sebacate allows them to be more easily molded and shaped, and it contributes to their improved mechanical properties. This makes it valuable in the production of plastics, films, and coatings where flexibility is a critical requirement. Product formulators looking to enhance their material’s performance should investigate the benefits of adding Monomethyl Sebacate to their formulations. Obtaining a quote from an established chemical supplier can help assess its cost-effectiveness for your specific application.

Furthermore, Monomethyl Sebacate is increasingly being recognized for its contribution to the development of sustainable and biodegradable materials. As industries worldwide pivot towards more environmentally friendly solutions, the use of intermediates that can form biodegradable polymers is on the rise. Its structure can be incorporated into polymer backbones designed to decompose naturally, offering an eco-conscious alternative to conventional plastics. Companies focused on green chemistry and sustainable product development will find Monomethyl Sebacate to be a valuable component in their research and production efforts.

Navigating the global supply chain for Monomethyl Sebacate, especially when seeking competitive pricing, often leads to exploring manufacturers in China. China's chemical industry is a major global player, offering a wide range of intermediates at competitive costs. For procurement managers, the process of buying involves careful supplier selection. This includes verifying quality certifications, understanding production capacities, and ensuring reliable logistics. Requesting comprehensive product specifications and a detailed price list from potential manufacturers is a standard practice. Many suppliers offer this chemical as a readily available product, ensuring that it can be procured for both research-scale and large-scale industrial needs.

In essence, Monomethyl Sebacate (CAS 818-88-2) is a fundamental chemical intermediate with a broad spectrum of industrial relevance. Its chemical properties make it indispensable for polyester synthesis, plasticizer applications, and the advancement of biodegradable materials. For those looking to procure this compound, understanding its characteristics and the global supply chain dynamics, particularly the offerings from China, is crucial for informed purchasing decisions and successful integration into manufacturing processes.
