Can 3-Bromo-3-methylpentane be matched by the formula C6H13Br alone?

No. C6H13Br covers multiple constitutional isomers. CAS 25346-31-0 identifies the structure with bromine and a methyl group on carbon 3 of the pentane chain. Confirm the full name, CAS number, structure and chromatographic identity rather than substituting another bromohexane with the same formula.

Which batch controls matter for 3-Bromo-3-methylpentane?

Specify GC assay, named constitutional isomers, elimination-derived alkene impurities, water, acidity or HBr, color or appearance and relevant residual precursors. The inquiry should also state quantity, container size, storage conditions and the downstream reaction acceptance criterion so the offered batch can be assessed consistently.

3-Bromo-3-methylpentane CAS 25346-31-0

3-Bromo-3-methylpentane, also called 3-methyl-3-bromopentane or 3-methylpentan-3-yl bromide, CAS 25346-31-0, EC 246-878-0, is a tertiary alkyl bromide with molecular formula C₆H₁₃Br and molecular weight 165.07 g/mol. It is a constitutional isomer of other tertiary hexyl bromides and should not be treated as identical to 2-bromo-2-methylpentane. Its reaction behavior commonly involves ionization and substitution/elimination competition, so GC assay, alkene impurities, acidity, water and actual reaction selectivity are key purchase controls.

Applications and grade selection

3-Bromo-3-methylpentane may be evaluated in tertiary-alkylation, solvolysis, elimination and mechanistic studies. It is not a conventional SN2 reagent. Solvent, nucleophile or base, temperature and water can shift product distribution substantially.

Distinguish it analytically from 2-bromo-2-methylpentane and other C6H13Br isomers.
Set limits for alkenes, residual alcohol, acidity, water and route-relevant by-products.
Compare substitution-to-elimination ratio and final-product quality in the buyer’s reaction.

Storage and handling

Keep tightly closed in compatible packaging away from heat, ignition sources, moisture, bases and oxidizers under the current SDS. Monitor color and acidity during the qualified storage period.

Safety, documentation and procurement

Handle as a flammable, reactive organobromine intermediate using ventilation, suitable personal protection and ignition controls. Procurement should specify analytical limits, reaction, quantity, package, destination and transport documents.
