Okay, I'm going to try to do this all in one breath:

It is a yellow liquid at STP, and theoretically, you could get a bucket of it, but it'd cost you over $100K; I only found one instance of it in nature--it appears to have anti-microbial properties (?); as far as reactivity, it undergoes reactions that are seen in molecules containing double bonds, but not aromatic compounds, which makes sense.

Phew! Great questions!
