Description

Di-n-Decyl Phthalate-3,4,5,6-D4 is a deuterium-labeled analog of di-n-decyl phthalate, a high-molecular-weight phthalate ester plasticizer. This compound is specifically designed for use as an internal standard in analytical chemistry, enabling precise quantification and method development via mass spectrometry. It is essential for researchers and quality control laboratories in the polymer, environmental monitoring, and regulatory compliance sectors who require high-purity isotopic standards for trace analysis.

Application

• Internal Standard for Mass Spectrometry (MS): Primary use as a quantitative reference standard in GC-MS and LC-MS analysis of phthalate esters.
• Polymer Research & Development: Used in studies investigating the migration, leaching, and degradation of plasticizers from PVC and other polymers.
• Environmental Analysis: Critical for the accurate detection and measurement of phthalate contaminants in water, soil, and air samples.
• Food Safety & Packaging Testing: Enables compliance testing for phthalate migration from packaging materials into foodstuffs.
• Toxicological & Metabolic Studies: Serves as a stable isotope-labeled tracer in pharmacokinetic and biomonitoring research.
• Quality Control & Method Validation: Provides a reliable benchmark for calibrating instruments and validating analytical methods in industrial and commercial laboratories.
