Once you have received the sample, you have to know 2 simple testing methods to verify its quality. Through 1hnmr we can make the structure is correct, and hplc will show its purity and impurities.

#1. Solvent used for 1HNMR

To run nmr, you have to dissolve the target molecule first, you need to find the right solvent first.

As we have mentioned its solubility above, it is insoluble in water and ethanol but soluble in DMSO, so you can use DMSO to dissolve it to run 1hnrm testing. Our spectrum tested by this method is down below in our download section, please check.

#2. Method for HPLC testing

To run hplc testing on purity, we must choose the right column and mobile phase, no much importance on the brands for hplc equipments.

Column: C18; size: 4.6*50mm; mobile phase: B(acetonitrile), A(0.02% NH4Ac); Gradient elution(B%).

Of course, this is just our method for moa and there are other different methods out there for your to explore. We found one patent for the hplc method too, please check below.
