Description

Bromosulfalein CAS NO 71-67-0 is a diagnostic agent primarily used in liver function testing. This compound is valued for its specific uptake and excretion by the liver, making it a critical tool for assessing hepatic health and function. It is essential for clinical diagnostics, pharmaceutical research, and biochemical studies where accurate liver performance evaluation is required.

Application

• Liver Function Testing (BSP Test): The primary application is as an intravenous diagnostic dye for the Bromosulfalein (BSP) retention test, a standard clinical procedure to evaluate liver excretory capacity and detect hepatic impairment.
• Clinical Diagnostics: Used in hospital and clinical laboratory settings for the assessment of liver diseases such as cirrhosis, hepatitis, and obstructive jaundice.
• Pharmacological Research: Employed in preclinical and clinical studies to investigate drug-induced liver injury (DILI) and to study the effects of new therapeutic agents on hepatic function.
• Physiological Studies: Utilized in research to understand hepatic blood flow, organic anion transport mechanisms, and biliary excretion pathways.
• Reference Standard: Serves as a high-purity chemical reference standard in analytical laboratories for method development and quality control of diagnostic kits.
