Products Description
4‑Chloro‑3‑methylphenol takes the form of colourless crystals. Its melting point is 66 °C (or 55.5 °C) and boiling point is 235 °C. At 20 °C, one gram of this substance dissolves in 250 mL water, and its solubility rises markedly in hot water. It dissolves freely in organic solvents such as benzene, ether, ethanol, acetone, chloroform and petroleum ether.
This compound is steam‑volatile. It is deployed in organic synthesis for the manufacture of dyes and film preservatives, and it also sees frequent use as a preservative for pharmaceuticals.
