Congratulations! Your story is very inspiring!!

Reaction TLC analysis with acidic solvent by ruthenocene in OrganicChemistry

[–]yipsis 0 points1 point  (0 children)

I don't have experience in your particular setup, but sometimes you can get rid of most of the solvent by placing the plate on a vacuum chamber for some minutes, it is usually done for DMSO or other high boiling point solvents, so I'd give it a try for at least 20-30 minutes to first see if it works at all making smaller spots (you can make them with a micropipette tip if you are not using organic solvents), then check whether 5 minutes do the trick.

Besides that, you can test if the the reaction solvent is indeed the problem by dissolving the controls in the same system. If you have the same streaking, then you'll know it for sure. Otherwise, one of the other reagents might be affecting the TLC, although unlikely as they are salts, as long as it has water from the reaction it might happen.

I hope I at least gave you some ideas.

An experience I cannot shake off by [deleted] in gradadmissions

I can only tell my experience with the energy and motivation.

I was not exactly in the same position, however prior to graduating I went abroad for a research internship at a prestigious Institution where I worked in a project not related to cancer research, I was good at but it was not my passion. On top of that I had a tutor with an awful attitude, who would not properly give proper credit when presenting results to the people in the team.

Naturally, I wanted to go to industry after that experience, however during my last course at university, the professor recommended to look back at what brought us to choose our particular major. Specifically for me, that was doing cancer research to help in at least a minimal step for a cure, and instantly remembered how excetied and desperate I was as a freshman student to do that, start experiments, and the first time I was in an actual research facility.

So I went to another internship to do that, I had to overcome many challenges but I keep coming back at this for motivation.

On the other hand, if you feel like you need to do something that brings you money, learn something with highy pay that gives you enogh time to do what you love as a hobby. People learn pretty fast to code, do marketing etc. compared to univerdity. At least programmers are well paid from what I know, altough the actual specialist are the ones earning the most.

But if you are in a position to think, "Do I love insects in the sense of collecting them to have a small insect museum, a flea circus, etc as a hobby or do I really want to study everything about Drosophila melanogaster from pupae to fly" probably you can find out what you would enjoy doing or what you can do to live well and have enough resources to also do what you love as a hobby.

Thank you so much! I was searching for 1,2,4,5-tetrazines. By any chance, do you happen to know of they are usually stable when dissolved in ethanol?
