impurities in CDCl3

Hello,

I'm doing NMR measurements on diluted (0.1 mM) solutions in CDCl3. When I
do overnight measurements on my compounds, I'm seeing extra peaks at 6.0
(quartet) and 2.0 ppm (doublet), and now I'm wondering what compound this
might be. I was thinking it might be amylene, but the spectrum I found for
amylene doesn't match this.

The supplier doesn't have certificates of analysis online; I've sent an e-
mail but don't have a reply yet. Maybe someone in this group can help me
out in the meantime?

Thanks in advance,

Marko Nieuwenhuizen
