Toluenes

Toluene (), also known as toluol (), is a substituted aromatic hydrocarbon with the chemical formula , often abbreviated as , where Ph stands for the phenyl group. It is a colorless, water-insoluble liquid with the odor associated with paint thinners. It is a mono-substituted benzene derivative, consisting of a methyl group (CH3) attached to a phenyl group by a single bond. As such, its systematic IUPAC name is methylbenzene. Toluene is predominantly used as an industrial feedstock and a solvent.

chemical compound

There are three isomers of toluidine, which are organic compounds discovered and named by James Sheridan Muspratt and August Wilhelm von Hofmann in 1845. These isomers are '''o-toluidine, m-toluidine, and p-toluidine', with the prefixed letter abbreviating, respectively, ortho; meta; and para''. All three are aryl amines whose chemical structures are similar to aniline except that a methyl group is substituted onto the benzene ring. The difference between these three isomers is the position where the methyl group (–CH3) is bonded to the ring relative to the amino functional group (–NH2); see i

Chlorotoluenes are aryl chlorides based on toluene in which at least one aromatic hydrogen atom is replaced with a chlorine atom. They have the general formula C7H8–nCln, where n = 1–5 is the number of chlorine atoms.

2,4-Diaminotoluene is an aromatic organic compound with the formula . It is one isomer of six with this formula. It is a white solid, although commercial samples are often yellow-tan.

MCPB, 2,4-MCPB, 4-(4-chloro-o-tolyloxy)butyric acid (IUPAC), or 4-(4-chloro-2-methylphenoxy)butanoic acid (CAS) is a selective phenoxybutyric herbicide. In the United States it is registered for use on pea crops before flowering, for post-emergence control of broadleaf annual and perennial weeds including Canadian thistle, buttercup, mustard, purslane, ragweed, common lambsquarters, pigweed, smartweed, sowthistle, and morning glory. It has low to moderate acute toxicity, with kidney and liver effects as the main hazard concerns.

Methoxytoluenes (methylanisoles or cresyl methyl ethers) are a group of three isomeric organic compounds with the formula CH3OC6H4CH3. They consist of a disubstituted benzene ring with methoxy group and one methyl group. All three are colorless flammable liquids which are soluble in organic solvents but poorly soluble in water. They are not of major commercial interest although they are precursors to the corresponding methoxybenzoic acids and methoxybenzaldehydes.

Methylbenzenediol, also known as dihydroxytoluene, may refer to:

Bromotoluenes are aryl bromides based on toluene in which at least one aromatic hydrogen atom is replaced with a bromine atom. They have the general formula C7H8–nBrn, where n = 1–5 is the number of bromine atoms.

Iodotoluenes are aryl iodides based on toluene in which at least one aromatic hydrogen atom is replaced with an iodine atom. They have the general formula C7H8–nIn, where n = 1–5 is the number of iodine atoms.
