Questions about Zuclomiphene testing

Can you tell zuclomiphene from enclomiphene?

Yes. They are the Z and E isomers of clomiphene, with the same mass, and HPLC separates them by retention time against reference standards.

What does the purity result include?

The main peak's share of the total peak area by HPLC-UV. Related compounds above the reporting limit show as separate peaks, and LC-MS can identify them on request.
