Description

Etifenin is a high-purity organic compound used as a key intermediate in the synthesis of diagnostic agents and other fine chemicals. Its primary commercial value lies in its role as a precursor for hepatobiliary imaging agents, where consistent quality and reliable supply are critical for pharmaceutical manufacturing. This product is essential for suppliers and manufacturers in the pharmaceutical, diagnostic imaging, and advanced research sectors requiring a stable and well-characterized chemical building block.

Application

• Pharmaceutical Intermediate: Primary use as a precursor in the synthesis of hepatobiliary diagnostic imaging agents.
• Diagnostic Agent Synthesis: Key building block for technetium-99m (99mTc) based radiopharmaceuticals used in liver and gallbladder imaging.
• Research & Development: Used in biochemical and medical research for studying liver function and developing new diagnostic compounds.
• Fine Chemical Production: Serves as an intermediate in the manufacture of other specialized organic molecules with iminodiacetic acid (IDA) functional groups.
• Contract Manufacturing: Supplied to CDMOs (Contract Development and Manufacturing Organizations) for the production of finished drug substances.

Quality Control

Our Etifenin is manufactured under a strict quality management system to ensure batch-to-batch consistency and high purity. The product is tested against rigorous in-house specifications, with a focus on identity, assay, and impurity profiles critical for pharmaceutical applications. A comprehensive Certificate of Analysis (COA) detailing purity, related substances, and residual solvents is provided with each shipment to support your quality assurance protocols.

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 in a dry environment to prevent moisture absorption, which can affect stability and handling properties.
