Description

p-Aminohippuric Acid Sodium Salt (CAS NO 94-16-6) is a high-purity organic sodium salt derivative of aminohippuric acid, serving as a critical diagnostic and research reagent. Its primary value lies in its role as a standard agent for measuring renal plasma flow and tubular function in clinical and pharmacological studies. This compound is essential for pharmaceutical R&D laboratories, clinical diagnostics manufacturers, and academic institutions conducting renal physiology and pharmacokinetics research.

Application

• Renal Function Testing: Standard agent for the precise measurement of effective renal plasma flow (ERPF) and para-aminohippurate (PAH) clearance in clinical diagnostics.
• Pharmacokinetic Studies: Used as a probe substrate to study organic anion transporter (OAT) function in drug absorption, distribution, and excretion research.
• Biochemical Research: Key reagent in studies of renal tubular secretion mechanisms and nephron physiology.
• Diagnostic Kit Manufacturing: Raw material for the production of in-vitro diagnostic (IVD) kits and calibrators used in hospital and reference laboratories.
• Pharmaceutical Reference Standard: Serves as a certified reference material (CRM) for quality control and analytical method validation in drug development.
