USP/EP-grade Valganciclovir Hydrochloride (CAS 175865-59-5), 98–102%, supplied wholesale by Zyntex to licensed producers. Oral ganciclovir prodrug antiviral API for tablets and oral solutions. CoA and SDS with every lot.
Valganciclovir hydrochloride is a white to off-white crystalline powder that is soluble in water. It is the L-valyl ester of ganciclovir; the ester greatly improves oral absorption, after which the body converts it back to active ganciclovir. It exists as a mixture of two diastereomers, whose ratio is controlled.
Pharmaceutical companies use it in film-coated tablets and powders for oral solution against cytomegalovirus infections, particularly in transplant recipients. Because ganciclovir is cytotoxic and genotoxic, both production and handling require containment.
Zyntex supplies valganciclovir hydrochloride from qualified API producers, only to licensed pharmaceutical companies. Other antiviral APIs in our range include Entecavir 1-hydrate, Remdesivir and Molnupiravir.

Why is valganciclovir used instead of ganciclovir?
The valyl ester is absorbed much better from the gut, so it allows oral treatment instead of intravenous ganciclovir.
Why does it require contained handling?
Ganciclovir, its active form, is cytotoxic and genotoxic, so exposure during production must be minimized.
