That doesn't sound like Bromine concentrate....it sounds more like ...well, a cheap dichlor mix.
 ???


I'll double check this evening.
I can't remember the brand, but it's in a pearlescent white bottle with purple graphics and a black cap.

no need, According to what Steve linked to, it explained that Bromine needs chlorine to activate.

From Steve's link:

"...It (bromine) was so stable that it was difficult to get into the water. Erosion feeders needed to be supplied with a mixture of one third chlorine and two thirds bromine so the chlorine could give the bromine a "kick".

And:


"...Bromine tablets are typically 1-bromo-3-chloro-5,5-dimethylhydantoin. When added to water they hydrolyze to become hypobromous acid. With bromine tablets a separate oxidizer is not necessary to make hypobromous acid, it is already an ingredient in the tablets. When the hypobromous acid reacts with a contaminant and is reduced, it becomes a bromide ion. You then get a build up of bromide ions in the water. After a while, you could just start adding an oxidizer to reactivate the bromide ions to hypobromous acid, but most people don’t, they just add more bromine tabs."
