IIRC, WFNA was used in Nike Ajax SAMs with aniline fuel in stage 2.
Slug ignition.
Same in Vanguard talking 19 fifties.

In Ignition! John D. Clark mentions that furfural comes from oat
hulls and Quaker Oats was glad to sell it. It was burned with WFNA or
RFNA, I didn’t see any reference about using it with peroxide.
The book seems essential to those involved with liquid rockets.

game-changing discoveries.

Troy -
This is scratching the deepest recesses of my brain but I remember
reading about a HTP-based vehicle in development circa the mid 2000s
that was supposed to use (perhaps wood alcohol?) alcohol as part of the
igniter.
The key factor was that it was basically a waste product from… grain
production? Quaker Oats, seriously, rings a bell.
I have no idea what keywords to use to find that article again but it
may well have been something in the nitric acid family and not HTP.

Matthew, you might be getting confused with Nitric Acid (RFNA or WFNA).
I can’t recall any straight alcohol being hypergolic with HTP. I would
definitely be quite excited to learn if there was something not too
exotic available.
