I'm entirely likely to be missing something, however from a mini= mal test in a document I'm unable to get org-latex-preview to do anything with the following= :
=23+LATEX=5FHEADER: =5Cusepackage=7Bmhchem=7D

 =40=40latex:=5Cce=7BCO2=7D=40=40

in a doc
My thoughts were= that perhaps what works for =5C( ... =5C) and =5C=5B ... =5C=5D (in term= s of org-latex-preview) could be extended to other forms of inline LaTeX = as well=3F
Given your response I'm guessing there are technical= challenges with this=3F
=46YI it seems to work fine for export= ing (see image below), I'd just quite like to benefit from the visual tid= iness achieved by the current LaTeX maths fragment rendering.

Oh, it jus= t comes to mind that you may be referring to non-TeX-based output formats= , where I can see that this could be a huge hassle.

Once ag= ain, (at this point in time) I am very loosely familiar with the innards = of org (I've just stumbled around loking for specifics with C-h f / C-h v= ),
so if I look like I'm making any strange/outragous statement= s, please apply a substantial pinch of salt :D

This should not be possible. Org cannot recognize al= l LaTeX syntax. If you cannot preview it, Org does not understand it.
