For professionals in the chemical industry, a thorough understanding of a compound's properties is fundamental to its safe and effective utilization. 4-Chlorotoluene (CAS 106-43-4) is a compound that requires careful attention to its chemical and physical characteristics. As a trusted supplier and manufacturer, we aim to provide comprehensive insights into this versatile intermediate.

Key Physical Properties of 4-Chlorotoluene
4-Chlorotoluene is a clear to colorless liquid at room temperature, possessing a distinct aromatic odor. Its key physical properties include:

• Melting Point: -93.9 °C. This extremely low melting point indicates that it remains liquid even at very cold temperatures, simplifying handling in many environments.
• Boiling Point: 162 °C. This moderate boiling point allows for purification via distillation and influences its behavior in reactions.
• Density: 1.07 g/ml at 25 °C. Being slightly denser than water, it will typically form a lower layer if immiscible with water.
• Vapor Density: 4.38 (vs air). Its vapor is significantly heavier than air, which is an important consideration for ventilation and safety in enclosed spaces.
• Refractive Index: n20/D 1.52. This optical property is often used for quality control and identification.
• Flash Point: 121 °F (49 °C). The flash point indicates the temperature at which the vapor can ignite in the presence of an ignition source. This is a critical parameter for fire safety protocols when handling the chemical.

Chemical Reactivity and Applications
The presence of the chlorine atom on the toluene ring makes 4-Chlorotoluene a valuable reactant in various organic synthesis pathways. The chlorine atom can undergo nucleophilic substitution reactions, while the methyl group can be oxidized or further functionalized. These reactive sites allow it to be used as a precursor for:

• Pharmaceutical intermediates
• Agrochemical components
• Dyes and pigments
• Specialty polymers
• Research chemicals

Safe Handling and Storage Considerations
Due to its properties, proper handling and storage of 4-Chlorotoluene are essential. Key safety considerations include:

• Ventilation: Work in well-ventilated areas or under a fume hood to prevent the accumulation of vapors, especially given its vapor density and flash point.
• Personal Protective Equipment (PPE): Always wear appropriate PPE, including chemical-resistant gloves, safety goggles, and protective clothing, to prevent skin and eye contact.
• Ignition Sources: Keep away from heat, sparks, open flames, and hot surfaces. As a flammable liquid, it requires careful management of potential ignition sources.
• Storage: Store in a cool, dry, well-ventilated place in tightly closed containers. Recommended storage temperature is often around 0-6°C for optimal long-term stability.
