In the pre­cise fields of bio­chem­istry and ana­lyt­i­cal chem­istry, researchers often encounter a con­found­ing issue : when using the same com­pound — such as Phos­pho­enolpyru­vate Monopotas­si­um Salt (PEP-K, ChemWhat®38422) for meta­bol­ic research, Phos­pho­enolpyru­vate Mono­cy­clo­hexy­lam­mo­ni­um Salt (PEP-CHA, ChemWhat®38345) for stud­ies, or Fer­ene Dis­odi­um Salt (Fer­ene, ChemWhat®25976) for pre­ci­sion met­al ion detec­tion — they find that despite the mar­ket being flood­ed with suppliers
