1,3-dichloro-2,4-difluorobenzene; CAS No.: 36556-37-3; 1,3-dichloro-2,4-difluorobenzene. PROPERTIES: This polyhalogenated aromatic compound possesses molecular formula C6H2Cl2F2 with molecular weight 181.00 g/mol. It generally appears as colorless liquid, exhibiting characteristic reactivity of chloro and fluoro substituents. The compound demonstrates good solubility in non-polar and slightly polar organic solvents like hexanes and dichloromethane, while being sparingly soluble in water. Its boiling point ranges between 115-120 C at 760 mmHg, and it exhibits IR absorption bands corresponding to the C-Cl (~800-600 cm??) and C-F (~1300-1100 cm??) stretches. Thermogravimetric analysis indicates decomposition onset above 150 C under nitrogen atmosphere. For optimal stability, 1,3-dichloro-2,4-difluorobenzene should be stored at 2-8 C in tightly sealed glass containers, protected from moisture and prolonged light exposure. As with halogenated compounds, it may cause severe skin burns and eye damage; therefore, rigorous containment and personal protection measures are essential during manipulation. APPLICATIONS: The versatile halogenation pattern of 1,3-dichloro-2,4-difluorobenzene makes it valuable as a building block in pharmaceutical and agrochemical syntheses. It serves as key intermediate in the preparation of diverse aryl-containing compounds through sequential nucleophilic aromatic substitution reactions, where the chloro and fluoro groups provide orthogonal reactivity as demonstrated in organic synthesis research (Journal of Fluorine Chemistry). Additionally, the compound participates in the synthesis of liquid crystal materials, where its dichlorodifluoro substitution pattern contributes to desired mesomorphic properties and thermal stability (Liquid Crystals). In materials science, it functions as monomer for preparing polyaryl ethers with enhanced flame retardancy, where the halogen substituents provide valuable fire-resistant characteristics (Polymer International). Furthermore, the compound serves as starting material in the development of halogenated solvents with specialized applications in chemical processes requiring specific polarity and solvation properties (Green Chemistry).
