Chloroxylenol, also known as para-chloro-meta-xylenol (PCMX), is a chlorine substituted phenol with a white to off-white appearance and a phenolic odor. The discovery of chloroxylenol was the result of efforts to produce improved antiseptics that began at the end of the 1800s. First synthesized in Germany in 1923, it was borne out of the study of coal tar components that began a decade earlier.^[2]
