1-methoxy-2-vinylbenzene; CAS No.: 612-15-7; 1-methoxy-2-vinylbenzene. PROPERTIES: 1-methoxy-2-vinylbenzene appears as a colorless to pale yellow liquid with a slight aromatic odor. Its molecular formula is C9H10O, corresponding to a molecular weight of approximately 138.18 g/mol. The compound exhibits a boiling point around 160-165 C at 760 mmHg and a density of about 1.02 g/cm? at 25 C. It demonstrates moderate solubility in common organic solvents such as ethanol, acetone, and diethyl ether but is sparingly soluble in water. The substance is sensitive to oxidation and may form explosive peroxides upon prolonged storage. Proper storage requires keeping it in a tightly sealed, amber glass container with a suitable stabilizer, 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: 1-methoxy-2-vinylbenzene serves as a versatile intermediate in organic synthesis, particularly valuable in the preparation of agrochemicals and specialty chemicals. Its vinyl and methoxy functionalities enable participation in polymerization reactions and nucleophilic substitutions, facilitating the synthesis of complex molecular frameworks (Journal of Organic Chemistry). In the fragrance and flavor industry, 1-methoxy-2-vinylbenzene functions as a flavoring agent and fragrance component, providing fruity and floral notes in various formulations (Perfume & Flavourist). Additionally, it finds application in the development of certain analytical reagents and chromogenic agents, where its methoxy and vinyl groups undergo selective reactions to produce colorimetric or fluorimetric signals (Analytical Chemistry). 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 (Tetrahedron Letters).
