Are 4-Bromoanisole and p-Bromoanisole the same isomer?

Yes. 4-bromoanisole and p-bromoanisole identify the para isomer, CAS 104-92-7. They are not 2-bromoanisole, 3-bromoanisole or bromobenzene. State the isomer, CAS number and assay basis in the purchase specification to prevent substitution.

What is the physical form of 4-Bromoanisole?

It is a low-melting solid or liquid depending on temperature, with a melting point of about 9-13 degrees C. Reference density is about 1.49-1.50 g/cm3, boiling point about 215-223 degrees C, flash point about 94 degrees C and refractive index about 1.56. Confirm colour and the supplied form for the offered grade.

Which specifications matter when purchasing industrial 4-Bromoanisole?

Agree assay by GC, water, colour, nonvolatile residue, brominated isomer impurities, anisole and other aromatic residues with the test methods. For coupling or intermediate manufacture, trace metals can also matter, and packaging should match the agreed isomer and purity limits.

What should be confirmed before bulk 4-Bromoanisole delivery?

Confirm liquid or solid form at the delivery temperature, drum or IBC format, container compatibility, quantity, previous cargo and unloading arrangement. Keep the material sealed and protected from heat, ignition sources and moisture, and follow the applicable storage-temperature range.
