Compound Overview

Xalnesiran sodium, also known as RO7445482 sodium, is a small interfering RNA molecule that targets a conserved region of the hepatitis B virus (HBV) genome. It can be used for research into chronic hepatitis B infection[1][2][3]. It is supplied as a white to off-white solid (C664H814F17N231Na57O415P57S6, MW 21009.2 as the free acid) at 95.90% purity.
