Description

Bis(2-Ethylhexyl)Phthalate (Ring-D4) is a deuterium-labeled internal standard critical for precise quantitative analysis in mass spectrometry. This compound matters for ensuring analytical accuracy and reliability in research and quality control environments where trace-level detection is paramount. It is primarily needed by analytical laboratories, environmental testing facilities, and pharmaceutical R&D departments conducting advanced mass spectrometry studies on phthalate esters and related compounds.

Application

• Internal standard for the quantification of Di(2-ethylhexyl) phthalate (DEHP) and related plasticizers via Gas Chromatography-Mass Spectrometry (GC-MS) and Liquid Chromatography-Mass Spectrometry (LC-MS).
• Critical component in stable isotope dilution assays for high-accuracy environmental monitoring of phthalate contamination in water, soil, and air samples.
• Essential reference material in metabolomics and pharmacokinetic studies investigating the absorption, distribution, metabolism, and excretion of phthalate esters.
• Used in the development and validation of regulatory-compliant analytical methods for food safety, consumer product testing, and occupational exposure assessments.
• Supports material science research investigating polymer plasticization and migration studies where deuterated analogs provide unambiguous tracking.
• Facilitates forensic and toxicological analysis in clinical and legal contexts requiring definitive identification and quantification of phthalates.
