Unlike minoxidil powder, the dosage form of tofacitinib for alopecia is not limited to topically applied formulations, it also has dosage forms of tablets for alopecia.

But it also showed efficacy against vitiligo.

As a matter of fact, there are many of its patient-assistance programs going on for other potential treatments.

As the GMP certificate for tofacitinib citrate is not available in China yet, this product is exported by chemical name or as intermediates.

Now check its prices from Pharmacompass so you will have a general price idea from other countries.

tofacitinib citrate export prices from pharmacompass

As you can see the price from China is 11352 USD per kg, though by a very small quantity.

Export prices from other countries are around 30000 USD/kg, so don’t be surprised when you receive offers of 40000usd.

We can see that its export prices from India are HIGHER than prices from China.

There is a greater chance that India is importing tofacitinib and reselling it to other countries.

Or they are buying the intermediates and selling these APIs, or making formulations in India.

So if you are looking to buy tofacitinib online, India will be the wrong direction to look, please note.

How To Test Tofacitinib Powder By NMR/HPLC?

Once you have received the sample, you have to know 2 simple testing methods to verify its quality.

Through 1hnmr we can make sure the structure is correct, and HPLC will show its purity and impurities.

#1. The 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, not much importance on the brands for HPLC equipment.

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.

Though it is in Chinese, if you have done HPLC before, you can see that the patent is using a longer column, with different Mobile Phases A and B by the unit.

From the table, you can also see the gradient elution method, the ratio of A/B by the minute(Their whole running time is 55 min)
