A deep understanding of chemical properties is fundamental for any industrial application, and Pentamethyldiethylenetriamine (PMDETA) is no exception. As a premier manufacturer and supplier of specialty chemicals, we are dedicated to providing our clients with comprehensive insights into the materials they source. PMDETA, a tertiary amine with the CAS number 3030-47-5, possesses a unique molecular structure and physical characteristics that make it indispensable in various industrial sectors.

Chemically, PMDETA is characterized as N,N,N’,N”,N”-Pentamethyldiethylenetriamine. Its molecular formula, C9H23N3, and a molecular weight of approximately 173.3 g/mol, define its composition. The molecule features multiple tertiary amine groups, which are the active sites responsible for its potent catalytic abilities. This structural configuration allows PMDETA to effectively catalyze the reaction between isocyanates and water, a crucial step in polyurethane foam formation. It also facilitates the urethane (gel) reaction, ensuring robust polymer network development.

Physically, PMDETA is described as a colorless to light yellow clear liquid. Its solubility in water and its ready solubility in organic solvents like benzene and alcohol make it highly compatible with a wide range of industrial formulations. This versatility ensures ease of integration into existing manufacturing processes. Key physical properties such as a boiling point around 198°C and a relatively low melting point of -20°C indicate its stability across various operational temperatures. Furthermore, its refractive index of 1.442 contributes to its characterization and quality control.

For procurement managers and R&D scientists, understanding these properties is vital when considering PMDETA for applications such as polyurethane foam production, or as an intermediate in agrochemical, pesticide, and pharmaceutical synthesis. Its capacity to act as an acylating agent for materials like polyamide and luminescent agents further highlights its diverse chemical utility. As a leading supplier from China, we ensure our PM DETA consistently meets high standards, with a typical assay of 98% minimum purity.

We are committed to providing our clients with not just high-quality chemicals but also the knowledge to leverage them effectively. Whether you are looking to buy PMDETA for catalysis or synthesis, understanding its chemical and physical properties is the first step towards successful application. We invite you to connect with us to discuss your specific needs and learn more about the dependable supply of PMDETA from our manufacturing facilities.
