p-Tolylmagnesium bromide(CAS: 4294-57-9)

p-Tolylmagnesium bromide (CAS: 4294-57-9) is a white crystalline solid. It has a molecular weight of 167.23 g/mol and is soluble in organic solvents like ethanol and acetone. It is highly reactive and can undergo various nucleophilic substitution reactions.

p-Tolylmagnesium bromide is typically synthesized by reacting p-tolylmagnesium chloride with sodium bromide in an ether solvent. The reaction is highly exothermic and requires careful temperature control.

p-Tolylmagnesium bromide (CAS: 4294-57-9) is used in the pharmaceutical industry for the synthesis of various organic compounds, in organic synthesis for the preparation of heterocycles, and in the polymer industry for the modification of polymer structures.

When handling p-Tolylmagnesium bromide (CAS: 4294-57-9), use appropriate personal protective equipment (PPE) such as gloves, goggles, and a lab coat. Store it in a cool, dry place away from heat sources. Use a fume hood during synthesis and follow standard safety procedures as outlined in the material safety data sheet (MSDS/SDS).
