Description

Diisodecyl Phthalate-D4 is a deuterated analog of the common plasticizer diisodecyl phthalate (DIDP), specifically labeled with four deuterium atoms. This compound is essential for advanced analytical and research applications where isotopic labeling is required to track molecular behavior without interference. It is primarily needed by researchers and quality control laboratories in the polymer, chemical, and life science industries for use as an internal standard in mass spectrometry, NMR spectroscopy, and metabolic studies.

Application

• Internal standard for the quantitative analysis of phthalate plasticizers (e.g., DIDP, DINP) via Gas Chromatography-Mass Spectrometry (GC-MS) and Liquid Chromatography-Mass Spectrometry (LC-MS).
• Deuterated tracer in environmental testing to study the fate, transport, and degradation of phthalate esters.
• Reference compound in Nuclear Magnetic Resonance (NMR) spectroscopy for method development and structural elucidation.
• Stable-isotope labeled standard for clinical and forensic toxicology assays.
• Research reagent in polymer science to investigate plasticizer migration, leaching, and polymer blend compatibility.
• Key material in the development and validation of regulatory compliance testing methods for consumer products and packaging.
