I have synthesized coumarin derivatives and one of the characterization is using UV-Vis. Since I don't have the standard for the synthesized compound, do I still need to run the standard for UV-Vis before I run my synthesized compound? Thanks in advance.
Thank you fro responding Dr Ritika.
I was planning on diluting my compound in chloroform. Since my starting material is in solvent form which salicylaldehyde and ethyl acetoacetate, do i need to dilute them in chloroform too?
Thank you for the suggestion. I was also planning to go for 1H NMR in the future.
Identification (identity confirmation) of organic molecule using ONLY UV-Vis data is highly controversial. Apply comparison with another structural- and molecular-analytical data of coumarine (m.p. + FTIR or NMR etc.).
is coumarin soluble in water? if not, is it possible to be soluble in high temperature?
Dear Dal..
If you need all other data related to coumarin derivatives use the following link
https://sdbs.db.aist.go.jp/sdbs/cgi-bin/direct_frame_top.cgi
then type coumarin... you will get proton nmr, car nmr, mass, ir, esr etc.
If you need only UV, you can use the following papers and link ...
