Anyone can help me on the chemistry notation

[ntusg]

I encountered a chemical (COOEt)2C, and I don't really know what does Et mean. I am not familiar with chemistry, but I guess this is something similar to -R which stands for -CH3, -CH2CH3 etc. Could anyone help to explain?

Thanks you very much.

Et represents an ethyl group, CH₃CH₂-

(COOEt)2C represents the compound diethyl malonate

Just visiting, but I learned something new, thanks Ygggdrasil!

Thank you, Ygggdrasil! I just got the same answer from other friends ...
