Tiopronin API Quality Control Measures

For Purity: HPLC or LC-Mass

We test its purity on every batch before they are released for export.

We need to make sure the quality is good before materials leave our warehouse.

Our purity requirement for our bulk tiopronin is 98.5% as min, normally the actual results will be over 99%.

For Structure: 1HNMR

We don’t test 1HNMR for every batch, but if you need it, we will test it for you.

As HPLC can also be used for identification with the comparison with the testing spectrum of RS, once the Retention Time of Peaks corresponds, it is the same material for sure.

Elemental Analysis:

We don’t normally do elemental analysis for this product, as it is not required by our SFDA or any other pharmacopeias.

If you have such requirements, we will test them in a third-party testing institution for you.
