With just a BS in Chem you are pretty much on par with liberal arts majors that have degrees not directly applicable to business. The jobs applicable to a chem degree are low paying, dead end, and very unstable (typically temp/contract) so you get no benefits and are forced to work for a parasite agency like Kelly or Aerotek skimming off a large part of what should be your pay. I would strongly not recommend getting a Chem major if you intend to hit the job market after graduating. I also would not recommend science grad school. the MS is treated as a BS and 2 years of experience or worthless. PhD programs are a freak show of exploitation and abuse by academia often leading to nothing but endless post-docs that are a career purgatory that many willnever escape.
The only reason to get a science BS is for professional school. Otherwise you are wasting your time and money.
