Usage

General Description

4-chloro-2-nitro-m-cresol is a chemical compound that is also known as PCMX, parachlorometaxylenol, and chloroxylenol. It is a chlorinated derivative of phenol that is commonly used as an antiseptic and disinfectant. It is effective against a wide range of bacteria, fungi, and viruses, and is commonly found in household cleaning products, hand soaps, and surgical scrubs. It works by disrupting the cell walls of microorganisms, leading to their destruction. However, it is important to use this chemical with caution, as it can be toxic in high concentrations and can cause skin and eye irritation. Despite these potential hazards, 4-chloro-2-nitro-m-cresol is an important ingredient in many products that help maintain proper hygiene and cleanliness.

Improved Protocol for Mononitration of Phenols with Bismuth(III) and Iron(III) Nitrates

A simple and efficient multigram procedure was developed for the selective mononitration of various activated phenols. The reaction proceeded smoothly with 0.5 equivalents of Bi(NO3)3 · 5H2O or Fe(NO3)3 · 9H2O in acetone at ambient temperature or at reflux. The desired products were isolated in 62-93% total yield and essentially no overnitrated compounds were detected.

Formation of 4-Halo-4-nitrocyclohexa-2,5-dienones on Nitration of p-Halophenols and p-Halophenyl Acetates.

Nitration of p-chloro-, p-fluoro-, and p-bromo-phenol or the corresponding p-halophenyl acetates at -40 deg C and below gives the 4-halo-4-nitrocyclohexa-2,5-dienones in addition to the 4-halo-2-nitrophenols.The dienones isomerize to the nitrophenols at temperatures between -40 deg C and 0 deg C.Nitration of 4-chloro-2-methylphenol or its acetate gives both 4-chloro-2-methyl-4-nitrocyclohexa-2,5-dienone and 4-chloro-6-methyl-6-nitrocyclohexa-2,4-dienone. 4-Chloro-3-methylphenol and its acetate give 4-chloro-3-methyl-4-nitrocyclohexa-2,5-dienone.
