Description

Bis(2-Ethoxyethyl) Phthalate-3,4,5,6-D4 is a deuterated analog of bis(2-ethoxyethyl) phthalate, a high-purity compound where four hydrogen atoms on the aromatic ring are replaced with deuterium. This deuteration is critical for applications requiring non-interfering internal standards in advanced analytical techniques. It is primarily utilized by research and development laboratories, as well as quality control departments in the chemical and pharmaceutical industries, where precise quantification and method validation are paramount.

Application

• As a stable isotope-labeled internal standard for the accurate quantification of phthalate plasticizers and their metabolites via Gas Chromatography-Mass Spectrometry (GC-MS) and Liquid Chromatography-Mass Spectrometry (LC-MS).
• In environmental analysis for tracing and measuring phthalate contamination in water, soil, and air samples with high precision.
• For metabolomic and pharmacokinetic studies in pharmaceutical research to track the absorption, distribution, metabolism, and excretion of related compounds.
• In polymer and materials science research as a deuterated tracer to study the migration and leaching behavior of plasticizers from various matrices.
• Supporting regulatory compliance testing and method development for agencies monitoring consumer product safety and environmental health.
