(2-Chloroethyl)benzene, a compound with the CAS number 622-24-2, presents a distinct set of physical and chemical properties that dictate its handling, storage, and application spectrum. NINGBO INNO PHARMCHEM CO.,LTD. ensures its products are well-characterized, providing essential data for users.

Physically, (2-Chloroethyl)benzene is characterized as a colorless liquid. It possesses a density of approximately 1.069 g/mL at 25°C and a relatively low melting point of -60°C, meaning it remains liquid under most ambient conditions. Its boiling point is reported in the range of 82-84°C at 16 mmHg, or up to 198.2°C at standard pressure. The flash point, a measure of flammability, is around 64°C, indicating it requires careful handling around ignition sources. Its solubility in water is minimal, a common trait for many halogenated aromatic hydrocarbons, which also influences its behavior in different reaction media.

Chemically, the reactivity of (2-Chloroethyl)benzene is largely governed by the presence of the chlorine atom on the ethyl side chain and the phenyl ring. The chlorine atom can participate in nucleophilic substitution reactions, making it a useful precursor for introducing various functional groups. The phenyl ring itself can undergo electrophilic aromatic substitution, although the ethyl substituent might influence the regioselectivity of such reactions. Computational analyses, such as Fukui function calculations, help identify the most reactive sites on the molecule for specific types of chemical transformations.

Understanding these properties is crucial for both synthesis and application. For instance, its low water solubility dictates that reactions involving it might be carried out in organic solvents. Its liquid state at room temperature simplifies handling and transfer compared to solid chemicals. The flammability necessitates appropriate safety measures in storage and processing areas. NINGBO INNO PHARMCHEM CO.,LTD. provides comprehensive safety data sheets (SDS) that detail these properties, ensuring responsible use of (2-Chloroethyl)benzene in industrial and research settings.
