Entecavir Monohydrate Product Overview

Entecavir monohydrate (C12H15N5O3·H2O) is a white to off-white crystalline powder that is slightly soluble in water. It is a guanosine analogue and contains about 5–7% water as the monohydrate.

Pharmaceutical companies use it in film-coated tablets and oral solutions for chronic hepatitis B. Tablets contain only 0.5 or 1 mg of API, so content uniformity, particle size control and contained handling are critical. Other antiviral APIs in our range include Valganciclovir Hydrochloride and Remdesivir.

Because it is highly potent, it must be handled in contained systems. Zyntex supplies it from qualified API producers with lot-specific documentation, only to licensed pharmaceutical companies.
