Product Identification & Isomer Overview
Monobromotoluene Isomer Family (C7H7Br)
Sourcing the exact structural isomer is critical when ordering organic intermediates for target synthesis. Bromotoluene belongs to the monobrominated aromatic hydrocarbon family with the chemical formula C7H7Br. The position of the bromine atom relative to the methyl group on the benzene ring defines three distinct positional isomers: 2-Bromotoluene (o-bromotoluene), 3-Bromotoluene (m-bromotoluene), and 4-Bromotoluene (p-bromotoluene).
Each isomer exhibits specific physical characteristics and reactivity patterns required for precise downstream chemical transformations.
Bromotoluene vs. Benzyl Bromide: Preventing Procurement Errors
A frequent and costly procurement error in chemical sourcing is confusing Bromotoluene with Benzyl Bromide (alpha-bromotoluene). While both share the identical molecular formula (C7H7Br), their chemical structures, hazard profiles, and industrial applications are completely different:
- Bromotoluene (Aryl Bromide): The bromine atom is directly attached to the aromatic benzene ring. It acts as a stable aryl bromide building block primarily used in transition-metal cross-coupling reactions and Grignard preparations.
- Benzyl Bromide (Side-Chain Brominated): The bromine atom is bound to the aliphatic methyl carbon. It is an extremely reactive alkylating agent and a dangerous lachrymator (tear-inducing agent).
Procurement Tip: Always verify the CAS registry number before placing orders to ensure you do not accidentally purchase Benzyl Bromide when your process calls for a stable ring-substituted methylbromobenzene.

Frequently Asked Questions (FAQ)
What is the main structural difference between Bromotoluene isomers and Benzyl Bromide?
The key distinction lies in the exact position of the bromine atom. In Bromotoluene isomers (o-, m-, and p-bromotoluene), the bromine is bound directly to the aromatic benzene ring, making it an aryl bromide substrate. In Benzyl Bromide (alpha-bromotoluene), the bromine attaches to the methyl carbon side-chain, making it an alkyl halide.
| Structural Feature | Bromotoluene Isomers (C7H7Br) | Benzyl Bromide (C7H7Br) |
|---|---|---|
| Bromine Location | Attached directly to aromatic ring | Attached to methyl side-chain |
| Compound Category | Aryl bromide building block | Alkyl halide / Strong lachrymator |
| Core Reactivity | Transition-metal cross-coupling & Grignard | Nucleophilic alkylation reactions |
| CAS Numbers | 95-46-5 (o-), 591-17-3 (m-), 106-38-7 (p-) | 100-39-0 |
