A chemistry PhD qualifies you to do advanced research in chemistry -- nothing more. If anything a PhD will work against a candidate in a general industry tech role, because the assumption is they either a) failed in the academic job market for whatever reason, or b) will get bored in a non-research role and split early.

Personally I'm biased against chem/bio/physics etc. PhDs who come in for development jobs because the ones I've known have had terrible, mind-blowingly bad coding practices drilled into them since undergrad and are strangely more resistant to learning best practices than those from more tech-related fields.
