Bromotoluene
group of ortho, meta, para isomers
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.
Monobromotoluene
Monobromotoluenes are bromotoluenes containing one bromine atom. There are three isomers, each with the formula C7H7Br.
Properties
The isomers differ in the location of the bromine, but have the same chemical formula.
Benzyl bromide is an isomer, which has a bromine substituted for one of the hydrogens of toluene's methyl group, and it is sometimes named α-bromotoluene.
Preparation
A laboratory route to p-bromotoluene proceeds from p-toluidine, which is diazotiized followed by treatment with copper(I) bromide.
Uses
Bromotoluenes are precursors to many organic building blocks. For example, the methyl group may be oxidized using potassium permanganate to form the corresponding bromobenzoic acid. The methyl group may also be partially oxidized to form bromobenzaldehyde.
The public source identifies “Bromotoluene” as group of ortho, meta, para isomers. This brief keeps that definition visible, then builds a research path around Bromotoluene, group and ortho.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Bromotoluene”, the useful work is to connect “group of ortho, meta, para isomers” to the records capable of establishing context and consequence.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Aug 6, 2026. The linked authority identifier is Q927010. None of the 0 selected statements returned an explicit reference.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The source lead contains qualifying language; that uncertainty should survive quotation, summary and reuse. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
