Hello Everybody,

I am just wondering if somebody can tell me a commercial source (US, Canada or Europe) for some of the "dronic acids:
alendronic acid
ibandronic acid
zolendronic acid
pamidronic acid

I was only able to find couple of them (etidronic acid). Google shows some medications based on dronic acid but I am looking at pure compounds for method development.

Thank you very much,

Vlad
