In the realm of chemical manufacturing, understanding the fundamental properties and structural characteristics of raw materials is essential for innovation and efficient production. 4-Chlorophenol (CAS 106-48-9) stands out as a versatile chemical intermediate, and its utility is directly linked to its molecular makeup and physical attributes. As a provider of high-quality chemical intermediates, we aim to shed light on what makes 4-Chlorophenol such a valuable compound.

Decoding the Structure: 4-Chlorophenol (CAS 106-48-9)

4-Chlorophenol, with the chemical formula C₆H₅ClO, is an organochlorine compound and a derivative of phenol. Its structure consists of a benzene ring substituted with a hydroxyl group (-OH) and a chlorine atom (-Cl). The '4-' designation indicates that the chlorine atom is positioned at the para position relative to the hydroxyl group on the benzene ring. This specific arrangement of functional groups significantly influences its reactivity and physical properties.

Key Physical and Chemical Properties

The properties of 4-Chlorophenol are critical for its application as an intermediate:

• Appearance: It is typically found as a white crystalline solid. This solid form, often in powder or crystal aggregates, is important for handling and storage.
• Odor: The compound possesses a distinctive, often described as unpleasant, odor. This is a characteristic that sensory evaluators and safety personnel note.
• Melting Point: With a melting point around 43.1 °C, it is a solid at room temperature but can melt relatively easily with slight warming. This property is relevant for certain processing techniques.
• Boiling Point: Its boiling point is approximately 219 °C, indicating moderate volatility at elevated temperatures.
• Solubility: 4-Chlorophenol exhibits limited solubility in water (about 27.1 g/L at 25 °C) but is readily soluble in many organic solvents such as ethanol, ethyl ether, and benzene. This solubility profile dictates its use in various reaction media.
• Acidity: As a phenol derivative, it is weakly acidic, with a pKa of 9.41. This acidity can be relevant in certain catalytic or reaction conditions.

How Properties Drive Applications

The specific positioning of the chlorine atom and the hydroxyl group on the benzene ring imbues 4-Chlorophenol with reactivity that is essential for its role as an intermediate. For instance:

• The hydroxyl group can be readily derivatized, and the chlorine atom can be displaced or influence reactions elsewhere on the ring. This dual functionality makes it a versatile starting material for synthesizing complex molecules needed in pharmaceuticals and agrochemicals.
• Its solvent capabilities, stemming from its polarity and solubility in organic media, are leveraged in applications like mineral oil refining.
