Understanding the Chemical Profile of 3-Chloropropylbenzene (CAS 104-52-9)

3-Chloropropylbenzene, also known by synonyms such as (3-chloropropyl)benzene or 3-phenylpropyl chloride, is an organochlorine compound with the molecular formula C9H11Cl and a molecular weight of 154.64 g/mol. Its structure consists of a benzene ring attached to a three-carbon propyl chain, with a chlorine atom at the terminal position of the propyl chain. This structural arrangement imbues it with specific chemical characteristics:

• Appearance: It is typically observed as a clear, colorless to light yellow liquid.
• Solubility: It exhibits slight solubility in water but is generally soluble in common organic solvents.
• Reactivity: The presence of the chlorine atom makes it susceptible to nucleophilic substitution reactions. This allows for the introduction of various functional groups onto the propyl chain, opening doors for diverse synthetic pathways. The phenyl group provides aromatic character and can participate in electrophilic aromatic substitution reactions under appropriate conditions.
• Physical Properties: With a boiling point of approximately 220.2 °C at 760 mmHg and a flash point of 87.2 °C, it possesses moderate volatility and flammability characteristics relevant for industrial handling.
