《Oxidative chlorination of various iodoarenes to (dichloroiodo)arenes with chromium(VI) oxide as the oxidant》 was published in Journal of Chemical Research, Synopses in 1999. These research results belong to Kaimierczak, Pawet; Skulski, Lech; Obeid, Nicolas. Quality Control of 3,5-Dichloro-4-methoxybenzoic acid The article mentions the following:
Chromium(VI) oxide dissolved in a mixture of acetic acid with concentrated hydrochloric acid converts, at or near room temperature, iodoarenes to (dichloroiodo)arenes, in a very simple and efficient procedure. In the experimental materials used by the author, we found 3,5-Dichloro-4-methoxybenzoic acid(cas: 37908-97-7Quality Control of 3,5-Dichloro-4-methoxybenzoic acid)
3,5-Dichloro-4-methoxybenzoic acid(cas: 37908-97-7) belongs to organochlorine compounds. The wide structural variety and divergent chemical properties of organochlorides lead to a broad range of names, applications, and properties. Organochlorine compounds have wide use in many applications, though some are of profound environmental concern, with TCDD being one of the most notorious.Quality Control of 3,5-Dichloro-4-methoxybenzoic acid
