A laboratory route to 2- and 4-chlorotoluene proceeds from 2- and 4-toluidines (i.e. 2- and 4-aminotoluene). These compounds are diazotized followed by treatment with cuprous chloride. [1] Industrially, the diazonium method is reserved for 3-chlorotoluene. The industrial route to 2- and 4-chlorotoluene entails direct reaction of toluene with ...

All three have been synthesized by various routes: 1-Bromo-2-chlorobenzene: from 2-chloroaniline, via diazotization followed by a Sandmeyer reaction [1]; 1-Bromo-3-chlorobenzene: by (3-chlorophenyl)trimethylgermanium by electrophilic substitution [2] [better source needed]
o-Toluidine (ortho-toluidine) is an organic compound with the chemical formula CH 3 C 6 H 4 NH 2. It is the most important of the three isomeric toluidines . It is a colorless liquid although commercial samples are often yellowish.
1-Bromo-3-chloropropane is an organohalogen compound with the formula Br(CH 2) 3 Cl. It is a colorless liquid, produced by free-radical addition of hydrogen bromide to allyl chloride. [1] It is used as an alkylating agent to install the –(CH 2) 3 Cl [2] [3] and –(CH 2) 3 – groups. [4] For example, it is a precursor to 4-chlorobutyronitrile.
Seed oils — plant-based cooking oils often used in processed, packaged foods — have been linked to an increased risk of colon cancer, according to a new study published in the medical journal Gut.
January 3, 2025 at 8:32 AM. WASHINGTON (Reuters) - -Alcoholic drinks should carry a label warning consumers about their cancer risks, the U.S. Surgeon General said in an advisory on Friday, noting ...
[1] Some dichlorotoluenes are precursors to commercial pesticides. 2,4-Dichlorotoluene is the precursor to pyrifenox, butafenacil, and the pyrazole derivatives pyrazoxyfen and [pyrazolynate]]. The 2,6 isomer is a precursor to dichlobenil (2,6-dichlorobenzonitrile). 3,5-Dichlorotoluene is used to prepare propyzamide. [2]
