Azithromycin Dihydrate

Azithromycin dihydrate, 9-deoxo-9a-aza-9a-methyl-9a-homoerythromycin A dihydrate · CAS 117772-70-0

A 15-membered azalide with a hydrate form that has to be preserved through drying — buyers test water content and the azithromycin B impurity together. Supplied as the dihydrate only; the anhydrous form is not offered because it re-equilibrates in suspension.

Part of the anti-infective line. These are the products where a supplier switch triggers a regulatory filing, so the CoA history and the impurity methods travel with the material.
