If you are referring to Bromobenzene being a List I or II chemical, then I can tell you it is not, see Watched Chemicals in the US (https://www.thevespiary.org/rhodium/Rhodium/chemistry/watched.html)

"But...", you may say, "Bromobenzene is covered in the list of watched chemicals in that document!"
To which I would reply - Yes, but so is Phenylmagnesium Bromide, and as you need one of them anyway, then why not buy the cheapest and most common of the two?
