Let me briefly describe this synthesis process, I don't think anyone would find 5F more difficult if they used our precursors and methods, as many of my customers in the forum can attest.
The bromine used in the synthesis of 5C is 5-bromo-1-pentene, and 5F uses 1-bromo-5-fluoropentane, which does not cause difficulties in the synthesis!
If a supplier tells you that a certain NOIDS synthesis is difficult, then you can come to us, in this field we can customize the production of any NOIDS precursor and synthesis solution for you! Success is absolutely guaranteed and failure is fully refundable!
