Description

Di-(2-Ethylhexyl) Phthalate (Ring-U-14C) is a carbon-14 radiolabeled analog of the common plasticizer DEHP, specifically designed for advanced research and analytical applications. This compound is essential for conducting precise metabolic, environmental fate, and pharmacokinetic studies where tracking the molecule is critical. It is primarily utilized by research scientists and quality control specialists in the pharmaceutical, environmental testing, and polymer research sectors.

Application

• Tracer Studies in Toxicology & Metabolism: Used as a radiolabeled tracer to investigate the absorption, distribution, metabolism, and excretion (ADME) profiles of phthalate compounds in biological systems.
• Environmental Fate Analysis: Employed in research to track the degradation, leaching, and bioaccumulation of DEHP in soil, water, and sediment.
• Polymer Science Research: Serves as a tool to study the migration, stability, and interaction of plasticizers within polymer matrices under various conditions.
• Analytical Method Development: Acts as an internal standard or reference material in the development and validation of sensitive analytical methods like LC-MS for phthalate detection.
• Regulatory & Compliance Testing: Supports studies required for regulatory submissions concerning product safety and environmental impact.
