i feel stupid.
i was looking at spironolactone, noticing that it is steroidal, and realized it is not aromatic. neither is finasteride. only dutasteride has one aromatic part. so I can't measure finasteride with UV. and if any sugar is dissolved (it has many inactive ingredients) in the ethanol, that will throw off the visible light spectrum as well. what if generics have different inactive ingredients? not much I can do about that.
so i need the infared spectrum, and I think that C=C double bond and the C3-H bonds are the only things that will distinguish it from sugar. I hope these small peaks are far away from the C2-H and C-O and O-H bond peaks, and others, which will have huge magnitudes by comparison. I can look that up in my textbook.
As for the dutasteride, it has that aromatic benzene ring, which any benzene durivative can fake, but the CF3 bonds should also help. I hope any manufacturer making fakes just made sugar pills and not something to attempt to fool labs. I will have to use toluene or something closer as a standard for the UV to get an idea of the magnitude but not the exact frequency I should be looking for.
If someone can tell me the actual UV peak it should have, that would help a lot. Same with the other peaks.
