Description

Cystografin CAS NO 7170-91-4 is a specialized diagnostic agent belonging to the class of iodinated contrast media. This compound is critical for providing clear radiographic visualization in medical imaging procedures. It is primarily required by pharmaceutical manufacturers and contract research organizations (CROs) for the formulation of urological contrast solutions. Its reliable performance is essential for accurate diagnostic outcomes in clinical settings.

Application

• Primary Use in Urography: Formulation of injectable contrast media for intravenous pyelography (IVP) and cystography to visualize the urinary tract, including kidneys, ureters, and bladder.
• Diagnostic Imaging Agent: Key active pharmaceutical ingredient (API) in solutions used for X-ray and computed tomography (CT) imaging procedures.
• Pharmaceutical Intermediates: Serves as a high-purity intermediate in the synthesis of more complex iodinated contrast agents.
• Research & Development: Used in biochemical and pharmacological research to study renal function and imaging efficacy.
• Contract Manufacturing: Supplied to fill-finish facilities for the aseptic production of final sterile dosage forms.

Quality Control

Our Cystografin is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing to ensure it meets stringent specifications for pharmaceutical use, including identity, purity, and impurity profiles. Certificates of Analysis (COA) documenting compliance with relevant pharmacopeial standards (e.g., USP, EP) are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic nature, the container must be kept tightly sealed after opening to prevent moisture absorption, which can affect stability and performance.
