2-[2-(Methylamino)ethoxy]ethan-1-ol (CAS No. 85475-01-0) is a nitrogen-containing acyclic alcohol compound with the molecular formula C₅H₁₃NO₂ and a molecular weight of 119.16. Its structure consists of a methylamino group (-NHCH₃) connected via an ethoxy group (-OCH₂CH₂-) to the terminal hydroxyl group (-OH) of ethanol, forming a linear amphiphilic molecule. It is typically produced through alkylation reactions between methylamine and derivatives of ethylene oxide, resulting in a liquid product with a purity of ≥98% after purification, which meets ISO certification standards. Due to its bifunctional characteristics, this compound is widely used as an intermediate in pharmaceutical synthesis (e.g., for anticancer agents), as a modifier for polymer materials, and in the development of surfactants. Its low boiling point (90-91°C at 4.5 Torr) and weak basicity (pKa ≈ 14.4) provide flexibility for controlling specific reaction conditions.
