Through some research it seems that the general Amber force field (gaff) might be the most suitable for such a molecule, although I wanted to see if anybody has some other potential suggestions.
There are plenty of general force fields, CGenFF derived from CHARMM,
OPLS supports many species, etc. There are web servers for all of these.
Without knowing what you're actually trying to parametrize, it's hard to
be more specific.
