3-ethynyloxetane; CAS No.: 1290541-38-6; 3-ethynyloxetane. PROPERTIES: 3-ethynyloxetane appears as a colorless to pale yellow liquid with a slight odor. Its molecular formula is C5H6O2, corresponding to a molecular weight of approximately 102.09 g/mol. The compound exhibits a boiling point around 100-105 C at 760 mmHg and a density of about 1.0 g/cm? at 25 C. It demonstrates moderate solubility in common organic solvents such as methanol, acetone, and diethyl ether but is sparingly soluble in water. The substance is sensitive to strong bases and Lewis acids, which may cause alkyne polymerization or ring-opening reactions. Proper storage requires keeping it in a tightly sealed, amber glass container in a cool, dry location away from direct sunlight and heat sources. The temperature should be maintained below 10 C if possible. Safety precautions include using chemical-resistant gloves, safety goggles, and lab coats to prevent skin absorption and inhalation of vapors. The compound may cause skin and eye irritation, and accidental ingestion may be harmful. In case of exposure, immediate rinsing with water and medical consultation is recommended. APPLICATIONS: 3-ethynyloxetane serves as a versatile intermediate in organic synthesis, particularly valuable in the preparation of agrochemicals and specialty chemicals. Its oxetane and ethynyl groups enable participation in click chemistry reactions and nucleophilic substitutions. In pharmaceutical research, it functions as a building block for creating bioactive molecules, including certain anticancer agents and enzyme inhibitors. Additionally, it finds application in the development of certain analytical reagents and chromogenic agents, where its ethynyl group undergoes selective reactions to produce colorimetric or fluorimetric signals. The compound is also employed in the synthesis of certain heterocyclic compounds and conjugated systems used in materials science for their optical and electronic properties.
