Description

Ditaurobilirubin is a conjugated form of bilirubin, specifically the ditaurate conjugate, which is a key metabolite in the study of bile pigment biochemistry. This compound is of significant value as a high-purity reference standard and a critical biochemical reagent for research and diagnostic applications. It is primarily needed by pharmaceutical R&D laboratories, diagnostic kit manufacturers, and academic institutions conducting advanced studies in hepatology, metabolism, and clinical chemistry.

Application

• Biochemical Research Standard: Serves as a certified reference material (CRM) for the quantification and identification of bilirubin conjugates in biological samples.
• Diagnostic Assay Development: Used as a critical calibrator and control in the development and validation of clinical diagnostic tests for liver function and biliary disorders.
• Metabolic Pathway Studies: Essential for in-vitro studies investigating the hepatic conjugation, transport, and excretion pathways of bilirubin.
• Pharmaceutical Analysis: Employed in analytical method development (e.g., HPLC, LC-MS) for drug metabolism and pharmacokinetics (DMPK) studies related to liver-targeted therapies.
• Quality Control Reagent: Acts as a purity standard for quality assurance in the production of related biochemicals and diagnostic reagents.
