4,4'-Dichlorodiphenyl sulfoxide is an organosulfur compound with a melting point of 141-144°C (lit.) and predicted boiling point of 406.2±30.0°C. It has a density of 1.3778 (estimate) and flash point of 199.5°C. This compound is classified as toxic (LD₅₀: 500 mg/kg in mice, intraperitoneal) and should be handled with appropriate precautions (Safety code: S24/25 - avoid skin/eye contact). It is primarily used as:
A key intermediate in pharmaceutical synthesis (e.g., leprosy drug precursors)
A building block for polymers like polysulfones and polyethersulfones
A reagent in organic transformations.
Storage conditions recommend sealing in dry, room temperature environments. The compound produces toxic sulfur oxides and chloride fumes when burned.
