1-Chloro-2-phenoxybenzene(CAS: 2689-07-8)

1-Chloro-2-phenoxybenzene (CAS: 2689-07-8) is a crystalline solid with a molecular weight of approximately 225.6 g/mol. It has a pKa of around 9.9 in water. The compound is only slightly soluble in water but more soluble in organic solvents like ethanol and dichloromethane. It is moderately reactive towards nucleophiles and electrophiles, making it useful in various synthetic reactions.

1-Chloro-2-phenoxybenzene can be synthesized via a side-chain chlorination of 2-phenoxybenzoic acid. Commonly, this process involves heating the acid with thionyl chloride in an inert solvent like dichloromethane. The reaction is carried out in the presence of a catalyst, often a basic substance to enhance the reactivity. The yield is typically around 70-80%, with good selectivity towards the chloro substitution.

1-Chloro-2-phenoxybenzene is used in a variety of industries including pharmaceuticals, where it serves as a precursor for drug synthesis, and in the production of organic pigments. It is also utilized in the development of sensors and as a component in certain polymer formulations. Its versatile nature makes it relevant across multiple sectors.

When handling 1-Chloro-2-phenoxybenzene (CAS: 2689-07-8), it is important to use appropriate personal protective equipment (PPE) such as gloves, goggles, and a lab coat. Ensure the work is conducted in a fume hood to minimize exposure to vapors. Spills should be immediately cleaned up with appropriate absorbent materials. Always consult a safety data sheet (SDS) for detailed information on handling and disposal procedures.
