For example, 2,6-dichlorotoluene can be prepared by chlorination of 4-toluenesulfonyl chloride followed by desulfonation. [1] Some dichlorotoluenes are precursors to commercial pesticides. 2,4-Dichlorotoluene is the precursor to pyrifenox, butafenacil, and the pyrazole derivatives pyrazoxyfen and [pyrazolynate]].
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 ...
2,4-Dichlorobenzoic acid is an organic compound with the formula C 6 H 3 Cl 2 CO 2 H. It is one of more important of several isomers of dichlorobenzoic acid. It can be prepared by oxidation of 2,4-dichlorotoluene. [2] The coenzyme A thioester of 2,4-dichlorobenzoic acid is the substrate for 2,4-dichlorobenzoyl reductase.
The molecular mass and relative molecular mass are distinct from but related to the molar mass. The molar mass is defined as the mass of a given substance divided by the amount of the substance, and is expressed in grams per mol (g/mol). That makes the molar mass an average of many particles or molecules (potentially containing different ...
3,4-Dichlorophenol 3,5-Dichlorophenol Dichlorophenols are used as intermediates in the manufacture of more complex chemical compounds, including the common herbicide 2,4-dichlorophenoxyacetic acid (2,4-D).
C 7 H 6 Cl 2 Molar mass: 161.03 g/mol Appearance Colorless liquid Density: 1.254 g/cm 3, liquid Melting point: −17 to −15 °C (1 to 5 °F; 256 to 258 K) Boiling point: 205 °C (401 °F; 478 K) (82 °C at 10 mmHg)
2,4-Dichlorophenol (2,4-DCP) is a chlorinated derivative of phenol with the molecular formula Cl 2 C 6 H 3 OH. It is a white solid that is mildly acidic (pK a = 7.9). It is produced on a large scale as a precursor to the herbicide 2,4-dichlorophenoxyacetic acid (2,4-D).
C 7 H 3 Cl 2 N Molar mass: 172.01 g/mol Appearance white crystalline powder ... Dichlobenil is produced from 2,6-dichlorotoluene via the aldoxime. [1] References
