Description

Diethyl Phthalate (Ring-D4) is a deuterated isotopologue of the common plasticizer diethyl phthalate, where four hydrogen atoms on the aromatic ring are replaced with deuterium. This compound is a critical analytical standard and tracer used in advanced research and quality control, providing unmatched precision for spectroscopic and chromatographic methods. It is essential for scientists and quality assurance professionals in the pharmaceutical, environmental analysis, and polymer research industries who require high-purity, isotopically labeled materials for method development and validation.

Application

• Internal Standard for GC-MS and LC-MS analysis of phthalates and related compounds.
• Deuterated tracer in environmental fate and metabolism studies.
• Quantitative NMR (qNMR) reference material for purity determination.
• Critical component in method development and validation for regulatory compliance testing.
• Stable isotope-labeled standard for pharmaceutical impurity profiling and degradation studies.
• Research reagent in polymer science for studying plasticizer migration and interaction dynamics.
