jes, it is possible, only that the question is phrased wrong,
does the influence binaural beats have on the brain lead to increased production of chemicals in the brain?
answer: yes
for example:
Delta waves raise the amount of melatonin from the pituitary gland, which influences your endocrine system positively and even adds an intuitive dimension to one`s psyche. Delta waves also help reduce cortisol levels. Cortisol causes brain cell damage and speeds aging. It is a hormone that is released under stress and tends to overwork (fight or flight) the adrenal glands. And exhausted adrenals lead to serious health issues.

so yes, binaural beats that effectivly bring you down in deep states help effect of chemical balance, in some cases,
im sure too much binaural beats can cause imbalance, but even if you take a quick "deep" nap, you will feel refreshed after 30min, thanks to chemical production in your brain...
if binaural beats wouldnt effect the brain, then yes, they wouldnt have an effect on chemical household, but they do, so it does
