Description

2-Ethyl-3-(3-Propionylamino-2,4,6-Triiodophenyl)Propanoic Acid Sodium Salt is a high-purity iodinated organic compound, serving as a critical intermediate in the synthesis of advanced X-ray contrast media. Its value lies in providing a reliable and consistent building block for pharmaceutical manufacturers, ensuring the quality and efficacy of final diagnostic agents. This product is essential for R&D and production within the pharmaceutical and fine chemical sectors, particularly for companies developing non-ionic, low-osmolar contrast agents.

Application

• Pharmaceutical Intermediate: Primary use as a key synthetic precursor for iodinated X-ray contrast agents like Iopromide and Ioversol.
• Contrast Media Research: Enables the development and optimization of new, safer generations of radiographic contrast media in academic and industrial R&D laboratories.
• Fine Chemical Synthesis: Utilized in multi-step organic synthesis to introduce the triiodinated phenyl moiety into complex molecular architectures.
• GMP Manufacturing: Supplied under controlled conditions for use in Good Manufacturing Practice (GMP) compliant production lines for active pharmaceutical ingredients (APIs).
• Diagnostic Agent Production: Integral to the manufacturing supply chain for companies producing final formulated contrast media for medical imaging.

Quality Control

Our 2-Ethyl-3-(3-Propionylamino-2,4,6-Triiodophenyl)Propanoic Acid Sodium Salt is produced and tested under a strict quality management system. Each batch is analyzed to ensure it meets exacting standards for purity and consistency, suitable for pharmaceutical intermediate applications. Comprehensive Certificates of Analysis (COA) detailing identity, assay, and impurity profiles by HPLC are provided with every shipment to support your regulatory and quality assurance requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated place at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive) and light-sensitive; therefore, containers must be kept tightly sealed and away from direct light exposure to maintain stability and purity.
