Description

Bis(2-Methoxyethyl) Phthalate-3,4,5,6-D4 is a deuterated analog of bis(2-methoxyethyl) phthalate, a high-purity isotopically labeled compound essential for advanced analytical applications. This material is critical for use as an internal standard in mass spectrometry, enabling precise quantification and eliminating matrix effects in complex sample analysis. It is primarily required by analytical laboratories, pharmaceutical researchers, and environmental testing facilities engaged in method development, pharmacokinetic studies, and trace-level contaminant detection.

Application

• Internal Standard for Mass Spectrometry (GC-MS/LC-MS): Provides accurate quantification in analytical methods for phthalate analysis.
• Pharmaceutical Research: Used in drug metabolism and pharmacokinetic (DMPK) studies to track and quantify metabolites.
• Environmental Analysis: Enables the detection and measurement of trace levels of phthalate esters in water, soil, and air samples.
• Food Safety Testing: Supports methods for monitoring phthalate migration from packaging materials into foodstuffs.
• Biomedical Research: Facilitates precise measurement of phthalate exposure in toxicological and biomonitoring studies.
• Polymer Science: Serves as a labeled tracer in studies investigating plasticizer migration and polymer degradation.
