3,5-Dichlorophenol(CAS: 591-35-5)

3,5-Dichlorophenol (CAS: 591-35-5) is a white crystalline solid with a molecular weight of 168.01 g/mol. It has a pKa of approximately 8.5 and is slightly soluble in water. It is moderately reactive, particularly towards nucleophilic substitution reactions. This compound is commonly used in organic synthesis and as a precursor in the production of other chlorinated phenolic compounds.

3,5-Dichlorophenol is typically synthesized through the chlorination of phenol. The reaction involves treating phenol with chlorine gas in the presence of a Lewis acid catalyst such as iron(III) chloride. The yield is generally high, and the selectivity towards 3,5-dichlorophenol is good. This method ensures a clean and efficient synthesis process.

3,5-Dichlorophenol (CAS: 591-35-5) is used in various industries. It is a key precursor in the pharmaceutical industry for the synthesis of certain drugs. In the polymer industry, it serves as a stabilizer and antioxidant. It is also used in the production of sensors and semiconductors due to its unique chemical properties.

When handling 3,5-Dichlorophenol (CAS: 591-35-5), it is essential to wear appropriate personal protective equipment (PPE) such as gloves, goggles, and a lab coat. Work should be conducted in a fume hood to minimize exposure. Spills should be cleaned up immediately using absorbent materials. In case of eye or skin contact, wash thoroughly with water and seek medical attention. Always consult the Material Safety Data Sheet (MSDS) for detailed safety information.
