Dichlorophene | CAS No. 97-23-4

Q: What are the physical and chemical properties of Dichlorophene (CAS: 97-23-4)?

Dichlorophene (CAS: 97-23-4) is a crystalline compound with a molecular weight of approximately 164.01 g/mol. It has a low solubility in water but is soluble in common organic solvents. Chemically, it is reactive towards nucleophiles and can participate in substitution reactions. Dichlorophene is stable under normal conditions but should be stored in a cool, dark place to prevent photochemical degradation.

Q: How is Dichlorophene (CAS: 97-23-4) typically synthesized?

Dichlorophene (CAS: 97-23-4) is synthesized through the chlorination of phenol. Commonly, this involves the reaction of phenol with chlorine gas in the presence of a Lewis acid catalyst like iron(III) chloride. The reaction is exothermic and requires careful control of temperature to achieve high yield and selectivity.

Q: What industries use Dichlorophene (CAS: 97-23-4)?

Dichlorophene (CAS: 97-23-4) is primarily used in the pharmaceutical industry for the synthesis of intermediate compounds. It is also used in the production of certain polymers and in the development of sensors for detecting specific chemical species. Its reactivity makes it valuable in semiconductor manufacturing processes as well.

Q: What precautions should be taken when handling Dichlorophene (CAS: 97-23-4)?

When handling Dichlorophene (CAS: 97-23-4), it is crucial to wear appropriate personal protective equipment (PPE), including gloves and safety goggles. Store the compound in a well-ventilated area away from direct sunlight. In case of a spill, ensure the area is well-ventilated, and use appropriate containment measures. Always refer to the Safety Data Sheet (SDS) for detailed emergency procedures and storage guidelines.
