4-Chlorophenol (p-Chlorophenol) Product Overview
4-Chlorophenol (CAS 106-48-9), commonly known as p-Chlorophenol or para-Chlorophenol, is one of the three positional isomers of monochlorophenol. In this molecule, the chlorine substituent is located at the para position relative to the phenolic hydroxyl group.
With a melting point around 42–45°C, 4-Chlorophenol is normally handled as a crystalline solid at ambient temperature but can be maintained in molten form under controlled heating. It is used primarily as an intermediate and aromatic building block in organic synthesis.
Basic Information of 4-Chlorophenol
4-Chlorophenol (CAS 106-48-9), also known as p-Chlorophenol or para-Chlorophenol, is the para-substituted isomer of monochlorophenol. It has the molecular formula C6H5ClO and a molecular weight of 128.55 g/mol. At normal ambient temperature, 4-Chlorophenol is generally a crystalline solid and becomes molten when heated above its melting range of approximately 42–45°C.
It is primarily used as an aromatic intermediate in organic synthesis, including the preparation of pharmaceutical, agrochemical, dye, pigment and other specialty chemical intermediates.
