Method for analysing terminal alkyne precursor???

[chromeleon]

All I can say is that it's an "aromatic urea compound"

does this make any sense to you?

thanks

I'm sorry, but playing "twenty questions" is not an effective way to get help or suggestions.

If you look back at threads here on the Forum, you'll find that the most productive are the ones where the originator posts fairly specific questions, such as:
- some idea of what they are trying to accomplish (bioanalytical, process monitoring, . . .),
- what kind of levels,
- what kind of matrix,
- what they have already tried and/or considered.

The exact identity of the molecule(s) is not that important, but *some* detail (e.g., big or small? acidic or basic groups?) is helpful .

apologies. let me have a think about it and I'll come back. thanks
