Description

Ursodeoxycholylcysteic Acid is a chemically modified bile acid derivative, synthesized from ursodeoxycholic acid. This compound is valued for its role as a key intermediate in advanced pharmaceutical research and development, particularly for creating novel therapeutic agents. It is primarily utilized by research institutions and pharmaceutical companies focused on hepatobiliary and metabolic disease treatments, as well as in the synthesis of specialized biochemical probes.

Application

• Pharmaceutical Intermediate: A critical building block in the synthesis of novel bile acid-based drugs and prodrugs targeting liver and intestinal diseases.
• Biochemical Research: Used as a reference standard or reagent in metabolic pathway studies, particularly those involving bile acid conjugation and transport.
• Probe Development: Serves as a precursor for developing fluorescent or radiolabeled probes to study bile acid receptor interactions and cellular uptake mechanisms.
• Academic & Contract Research: Employed in university and CRO laboratories for investigating cholestasis, gallstone dissolution, and related metabolic disorders.

Quality Control

Our Ursodeoxycholylcysteic Acid is produced under strict quality management protocols to ensure high purity and batch-to-batch consistency, suitable for research and development purposes. Each lot is accompanied by a comprehensive Certificate of Analysis (COA) detailing purity, identity, and impurity profiles. We adhere to cGMP principles where applicable, and specifications can be aligned with client requirements for advanced pharmaceutical applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); ensure the container is sealed tightly after each use to minimize exposure to atmospheric humidity. For long-term storage, consider desiccants or an inert atmosphere.
