Well, it is combustible liquid but not too easily igniting. No other
dangers should be involved.

I have no exact values at hand but as a chemists educated guess I would
expect loss-factor to be very high. The reason behind this is the polar
nature of the molecule which will make it turn here and there and has
finite friction. (A short note with plenty of simplifications). Generally
thing is actually fairly easy to guess more or less right.
Go for polyethylene/polypropylene or teflon to make low-loss caps.
