Description

Bis(2-Ethylhexyl) Phthalate-D38 is a deuterium-labeled isotopologue of the common plasticizer di(2-ethylhexyl) phthalate (DEHP), specifically designed for analytical and research applications. This high-purity compound is essential for use as an internal standard in mass spectrometry, enabling precise quantification and eliminating matrix effects in complex sample analyses. It is a critical material for analytical chemists and researchers in environmental monitoring, polymer science, and biomedical fields who require uncompromised accuracy in trace-level detection and method validation.

Application

• Internal Standard for Mass Spectrometry (GC-MS/LC-MS): Primary application for accurate quantification of DEHP and related phthalates in environmental, food, and biological samples.
• Environmental Analysis: Tracing and quantifying phthalate contamination in water, soil, and air samples with high precision.
• Biomedical & Clinical Research: Used in metabolomic studies and for monitoring phthalate exposure and metabolism in human tissues and fluids.
• Polymer & Material Science: Research on plasticizer migration, leaching, and degradation kinetics within polymer matrices.
• Food Safety & Regulatory Testing: Ensuring compliance with global regulations by accurately measuring phthalate levels in food contact materials and packaging.
• Pharmaceutical Research: Investigating potential leachables from plastic medical devices and packaging systems.
• Method Development & Validation: A key reagent for developing robust, isotope-dilution analytical methods in accredited laboratories.
• Doping Control & Forensic Analysis: Potential use in specialized forensic applications requiring high-sensitivity isotope ratio measurements.
