So i run TLC of pure compound (i thought it's pure compound), but i got another spot that give fluorescence in UV 366 nm but doesnt show any spot in UV 254 nm. What kind of compound is that? I need detail explanation, thanks.
Can you spply more information about the 'pure' compound ? Isit isolated or amanufactured? Might it be unstable?
The compound must absorb the incident radiation to fluoresce. UV and IR absorption spectra may help ...
你用10%硫酸乙醇液浸泡一下,然后在90度烤板,看看显色斑点。
Many compounda can exhibit fluorescence, for example PAHs.
