3-Ethyl-3-oxetanemethanol（Cat No.:L016522）is a four-membered cyclic ether (oxetane) derivative featuring an ethyl group and a hydroxymethyl substituent at the 3-position. Its strained ring structure imparts unique reactivity, making it a valuable building block in synthetic and medicinal chemistry. The hydroxyl group allows for functionalization via esterification or ether formation, while the oxetane ring contributes to improved metabolic stability and altered physicochemical properties when incorporated into drug molecules. This compound is commonly used in the development of bioisosteres, advanced polymers, and pharmaceutical candidates to modulate solubility, permeability, and stability.
