Description

Iopromide is a non-ionic, water-soluble, iodinated contrast medium widely used in diagnostic imaging. Its primary value lies in its excellent safety profile and high radiopacity, which are critical for obtaining clear and detailed X-ray and computed tomography (CT) images. This compound is essential for manufacturers of pharmaceutical formulations, particularly those serving the global medical diagnostics and healthcare sectors. Iopromide CAS NO 73334-07-3 is a key ingredient in injectable solutions for vascular and body cavity examinations.

Application

• X-ray Contrast Media: Primary active pharmaceutical ingredient (API) in formulations for angiography, venography, and urography.
• Computed Tomography (CT): Used in contrast-enhanced CT scans of the brain, spine, and various body organs.
• Cardiovascular Imaging: Essential for coronary angiography and other procedures to visualize blood vessels and heart chambers.
• Myelography: Component in diagnostic solutions for imaging the spinal cord and subarachnoid space.
• Arthrography: Used in joint imaging to assess cartilage, ligaments, and joint capsules.
• Pharmaceutical Intermediates: Serves as a key intermediate in the synthesis of other specialized contrast agents.

Quality Control

Our Iopromide is manufactured and tested to meet the stringent requirements of major pharmacopoeias, including USP and EP monographs. Every batch undergoes rigorous analytical testing, including HPLC assay for purity, determination of related substances, residual solvents, and heavy metals to ensure compliance with pharmaceutical-grade standards. A comprehensive Certificate of Analysis (COA) is provided with each shipment, documenting full compliance with agreed specifications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated area at controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); the container must be kept tightly sealed to prevent absorption of atmospheric moisture.
