ISSUE:

Hello,
I would like to formulate the following compound: 6-amino-2-ethyl-7-oxo-5-methyl-3-nitro-3-octedial
and I have formulated it like this HOC-HC (CH2-CH3)-HCNO2-HCH- HC(CH3)-HC(NH2)-CO-CHO
but I think it must be wrong, since the 3nitro-3octodial does not fit me.
A greeting and thanks in advance

I hope it works for you, regards

Thank you very much for the help, now I see it more clearly. You have been very quick to reply. Until next time
