How do Vilanterol work?

Vilanterol , FDA approved new drug will be a big potential drug.

Original Route of Synthesis of  Vilanterol  yield is about 12%, impurity is 2%, unknown impurity is 1%.

EOS Med Chem use the new Route of Synthesis of Vilanterol , yield improve 26%.

Reduced Vilanterol  synthesis steps, Remove unknown impurity, Remove Toxic Chemicals， Impurity is less than 1%, Assay more than 99%, Water by KF less than 0.5%.

Below is EOS Med Chem Route of Synthesis of Vilanterol , each steps we have MSDS, COA, if you have interesting, pls contact me.

Welcome to Site Audit.

2018, EOS Med Chem got China TOP100 New Drug Manu.
