Mesitylene or 1,3,5-trimethylbenzene is a derivative of benzene with three methyl substituents positioned symmetrically around the ring. The other two isomeric trimethylbenzenes are 1,2,4-trimethylbenzene (pseudocumene) and 1,2,3-trimethylbenzene (hemimellitene). All three compounds have the formula C 6 H 3 (CH 3) 3, which is commonly ...
The trimethylbenzenes constitute a group of substances of aromatic hydrocarbons, which structure consists of a benzene ring with three methyl groups (–CH 3) as a substituent. [1] [2] Through their different arrangement, they form three structural isomers with the molecular formula C 9 H 12. They also belong to the group of C 3-benzenes.
1,2,4-Trimethylbenzene, also known as pseudocumene, is an organic compound with the chemical formula C 6 H 3 (CH 3) 3. Classified as an aromatic hydrocarbon, it is a flammable colorless liquid with a strong odor. It is nearly insoluble in water but soluble in organic solvents. It occurs naturally in coal tar and petroleum (about 3%).
(Mesitylene)molybdenum tricarbonyl arises from the reaction of molybdenum hexacarbonyl with hot mesitylene: [1]. Mo(CO) 6 + (CH 3) 3 C 6 H 3 → Mo(CO) 3 [(CH 3) 3 C 6 H 3] + 3 CO It can also be synthesized, with good yields by displacement of pyridine ligands of the trispyridine complex Mo(CO) 3 (pyridine) 3 in the presence of Lewis acids.
1,2,3-Trimethylbenzene is an organic compound with the chemical formula C 6 H 3 (CH 3) 3. Classified as an aromatic hydrocarbon , it is a flammable colorless liquid. It is nearly insoluble in water but soluble in organic solvents.

“When you didn’t get enough sleep or didn’t get good quality sleep, the likelihood that an extra 5 to 10 minutes of sleep could make a meaningful impact is pretty low,” Dr. Joseph ...
There are three trimethylbenzenes, three ethylmetylbenzenes, and two propylbenzene isomers. 1980s American gasoline contained about 3-4% C 3-benzenes. [ 1 ] 1,2,3-trimethylbenzene or Hemellitene
