Product Description
2,5,7,10-Tetraoxaundecane (CAS 4431-83-8) is a synthetic organic compound characterized by an undecane backbone containing four ether linkages. Its molecular skeleton is constructed from an eleven-carbon undecane main chain, where four oxygen atoms are inserted to form repeated ether bonds, forming a typical polyether architecture with regularly distributed ether functional groups. As a member of the polyether family, it exhibits a flexible molecular structure and favorable solubility in a variety of organic solvents. The rotation freedom of C–O–C ether bonds endows the molecule with great chain flexibility, which further brings unique rheological and interfacial properties. It can dissolve readily in many common organic media such as alcohols, esters, ketones and aromatic hydrocarbons, while its solubility in water can be tuned by the quantity of ether oxygen atoms within the molecule.
The presence of multiple ether groups also provides opportunities for its use in chemical synthesis, materials science, and pharmaceutical-related applications. The ether linkages are chemically stable under neutral and mild alkaline environments, and can participate in targeted derivatization reactions under specific catalytic conditions, opening pathways for molecular modification and functional grafting. In chemical synthesis, it can act as a reaction medium or building block; in materials science, its flexible polyether segment helps to adjust the toughness, hydrophilicity and processing performance of polymer materials. In pharmaceutical research, its biocompatible polyether skeleton makes it a promising candidate for drug carrier research and formulation auxiliary development.
It may serve as a useful intermediate for the preparation of polymers and other structurally complex compounds. It can undergo polymerization, grafting or crosslinking reactions to build polyether-modified macromolecules, and it can also be used to construct complex organic molecular frameworks by connecting with other functional monomers, helping chemists design custom functional polymer materials and fine chemical derivatives.
Depending on its purity, formulation, and physical state, 2,5,7,10-Tetraoxaundecane can exist as a colorless liquid or solid under ambient conditions. High-purity samples tend to show more distinct phase transition behavior; trace impurities will affect crystallization tendency, so commercial grades may appear as transparent free-flowing liquid or crystalline solid at room temperature. Its physical and chemical properties, including melting point, boiling point, and reactivity, may vary according to its molecular structure, composition, and the functional groups involved. Minor differences in isomer composition or residual impurities will shift thermal parameters such as melting and boiling points. Meanwhile, the rich ether groups dominate its chemical reactivity: it shows good resistance to hydrolysis under mild conditions, but may undergo cleavage of ether bonds under strong acid, high temperature or special catalytic environments. Such tunable thermal stability and reactivity make this polyether compound a versatile building block for diversified fine chemical R&D and manufacturing scenarios.
