In which commercial forms is Phenylmagnesium Bromide supplied?

It is normally supplied as a solution in THF, diethyl ether or another specified ether solvent rather than as an isolated dry solid. The inquiry must state solvent, nominal molarity or weight percentage, required quantity and the receiving system used for transfer.

How should the concentration of Phenylmagnesium Bromide solution be compared?

Use the reported active-base or Grignard assay and its titration method, not the nominal concentration alone. Confirm solvent, density or weight percentage where relevant, insolubles, hydrolysis products and batch retest date so calculations are based on the delivered solution.

What packaging and storage details matter for Phenylmagnesium Bromide?

Require a dry, inert-gas-protected package with compatible closure or valve and an agreed fill basis. Confirm transport classification, transfer connection, storage-temperature range and crystallization guidance for the selected solvent; water, acids, oxidizers and atmospheric moisture must be excluded under the current SDS.

Phenylmagnesium Bromide CAS 100-58-3

Phenylmagnesium Bromide , CAS 100-58-3 and EC 202-867-2 , is an arylmagnesium halide with formula C6H5BrMg and molecular weight 181.31 g/mol. CAS 100-59-2 was incorrect and has been corrected. The reagent is commonly supplied as an ether or THF solution, so procurement must state solvent, nominal molarity, active-base titration method, density, bromide or magnesium balance, hydrolysis products and water-reactive packaging requirements.

CAS: 100-58-3
Synonyms: Phenylmagnesium bromide, Bromophenylmagnesium, Bromo(phenyl)magnesium, Phenyl magnesium bromide
Einecs: 202-867-2
Molecular Formula: C₆H₅BrMg
Grade: Confirm solvent, nominal and assayed active molarity, titration method, density, water, hydrolysis products, residual bromobenzene, magnesium salts and storage controls against the current COA and SDS.
Package: State solvent, concentration, quantity, destination and receiving method; confirm a moisture-tight inerted container, solvent-compatible closure and transfer connection, fill, pressure and temperature limits, and dangerous-goods requirements against the SDS.

Identity and specification

Item	Verified purchasing information
Product	Phenylmagnesium Bromide
Correct CAS / EC	100-58-3 / 202-867-2
Neat-component formula	C6H5BrMg
Commercial definition	Solvent, active molarity and titration method required

Phenylmagnesium Bromide is a Grignard reagent used as a phenyl nucleophile in controlled synthesis. CAS 100-58-3 identifies the reagent, while solvent and concentration define the commercial solution. The pure-component formula does not describe the complete shipped mixture.

Quality controls for purchasing

Specify solvent, nominal molarity and the titration method used to report active concentration.
Control water, hydrolysis products, bromide or magnesium balance, residual bromobenzene and insoluble matter as appropriate.
Confirm density, temperature basis, package headspace, inert-gas protection and acceptable concentration range at receipt.

Applications and grade selection

Phenylmagnesium Bromide is used for carbon-carbon bond formation with compatible electrophiles. Conversion and selectivity depend on solvent, concentration, water exclusion, addition rate and temperature. A controlled laboratory trial should confirm reaction and quench behavior before scale-up.

Storage and handling

The solution is highly moisture sensitive and may release flammable gas on contact with water. Keep under dry inert gas in an approved moisture-tight container, control ignition sources and use trained handling. Follow the supplier SDS and site emergency procedure.

Documentation and quotation details

State solvent, target molarity and tolerance, titration method, impurity limits, package connection, quantity, destination and delivery temperature needs. Request a lot COA, current SDS, transport classification and package-handling instructions before order approval.
