2-(3,4-dichlorophenyl)oxirane; CAS No.: 52909-94-1; 2-(3,4-dichlorophenyl)oxirane. PROPERTIES: This compound features a 2-(3,4-dichlorophenyl)oxirane structure, combining a dichlorophenyl substituent and an epoxide group. It typically appears as a white to off-white crystalline solid with a molecular weight of approximately 193.0 g/mol (C8H6Cl2O). The melting point ranges between 80-85 C, and it exhibits moderate solubility in common organic solvents like ethyl acetate, dichloromethane, and tetrahydrofuran while being sparingly soluble in water. Proper storage requires a tightly sealed container in a cool, dry place. Safety considerations include wearing appropriate PPE. It is classified as a skin and eye irritant (GHS07) with the hazard statement H315-H319. APPLICATIONS: 2-(3,4-Dichlorophenyl)oxirane serves as a versatile intermediate in pharmaceutical and chemical synthesis. Its 2-(3,4-dichlorophenyl)oxirane structure allows for participation in various reactions, including ring-opening reactions of the epoxide group and electrophilic substitution at the dichlorophenyl ring. In medicinal chemistry, it is used to develop bioactive molecules targeting the central nervous system and inflammatory pathways. The epoxide group can be readily opened by nucleophiles to form chiral centers. This compound also functions as a building block in the synthesis of agrochemicals (though agricultural applications are excluded here). Academic studies employ it as a model compound in Organic Chemistry journals, focusing on the development of novel dichlorophenyl oxirane derivatives based on the 2-(3,4-dichlorophenyl)oxirane scaffold.
