Description

Inarigivir (Ori-9020, Sb-9000) is a high-purity, small-molecule pharmaceutical intermediate and research compound. This compound is critical for advanced antiviral research and development programs, particularly in the field of hepatitis B therapeutics. It is primarily utilized by pharmaceutical R&D laboratories, biotechnology companies, and contract research organizations (CROs) engaged in the discovery and synthesis of novel antiviral agents.

Application

• Antiviral Drug Development: Key intermediate in the research and synthesis of novel therapeutic agents targeting hepatitis B virus (HBV).
• Pharmaceutical R&D: Used as a reference standard and building block in medicinal chemistry for structure-activity relationship (SAR) studies.
• Biochemical Research: Employed in in vitro and in vivo studies to investigate mechanisms of action for immune modulation.
• Preclinical Studies: Serves as an active pharmaceutical ingredient (API) intermediate for formulation development and toxicology assessments.
• Contract Manufacturing: Supplied to CDMOs for the scale-up synthesis under cGMP conditions for clinical trial material production.

Quality Control

Our Inarigivir is manufactured under strict quality management systems to ensure batch-to-batch consistency and high purity suitable for research and development. Each lot is accompanied by a comprehensive Certificate of Analysis (COA) detailing identity, purity, and impurity profiles. We adhere to relevant guidelines for pharmaceutical intermediates, and specifications can be aligned with client requirements for preclinical and clinical development stages.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and must be kept under inert atmosphere or in a desiccator to maintain stability and prevent degradation.
