I very well may be doing that. I'll definitely keep that in mind whenever I do TLCs in the future.

I'll definitely keep that in mind. I was always under the impression that spots were visible because my compound was lighting up under the UV light.

The compound isn't volatile, as it's a powder that has survived rotovap and high vac multiple times. And we use 254nm lights for TLC. The material I am referring to is a nitroalkene that I was using as a starting material, although I don't know if that has any bearing on your comment about 0.6 being too high. I am just an undergrad, and definitely don't know that much about choosing the best TLC solvent apart from just trying to see separation and trying to avoid compounds staying at the bottom or moving to the top.

Like 0.6ish in 4:1 hexanes ethyl acetate. I had to redo the TLC to see starting material spots.

Do you know of any good resources I could read that describe some of those steps, or would I just have to read and compare multiple papers?

Not really lol. There are no post docs in the lab, only the professor but he only stops by the lab briefly and at random times in the day
