I would not go to tet letters, they get used as the butt of jokes for irreprpducible results.
What you need is hi-res mass spec, not HPLC per se.
This is, unfortunately the cost of doing business and proving you indeed have the compounds you claim when publishing in the more respectable organic chemistry journals.
Usually HNMR and FTIR is sufficient when the purpose of a paper is not purely organic chemistry (such as a materials science paper in Macromolecules).
If it's really good, perhaps look at Angewandte? I published a materials sci paper there that included some simple synthesis and they did not make me get a HRMS. I think a carbon may still be requested by reviewers, and may frankly be a plain good idea.
If you get it published, let us know here! Protecting group chem is always nifty!
