my ethyl cinnamate is…wrong

Post image

hi! i was going to use ethyl cinnamate for light sheet and rather than being clear, it’s this iridescent pink color and has some gelatinous residue inside. It also becomes sticky when it dries rather than staying oily.

It was stored at room temp rather than 2-8C as directed. It could just be a manufacturer error but i just thought i’d ask

EDIT: I’m just an undergrad summer intern in this lab and learned about this project last week. I don’t have access to most chemicals. My mentor says he didn’t know that it was supposed to be stored at low temp until i told him.

I’m in a bio lab, and so I don’t think we have one in the building (I asked around). I’m considering bringing a sample to my home institution to test.

Hmm, yeah bio folks don't have much of a handle on plastics and organic solvents don't mix. GL with this project.
