Description

Di-n-Nonyl Phthalate-3,4,5,6-D4 is a deuterium-labeled isotopologue of di-n-nonyl phthalate (DINP), a high molecular weight phthalate ester. This compound is specifically designed for use as an internal standard in analytical chemistry, providing unmatched accuracy for quantitative analysis and method development. It is essential for researchers and quality control laboratories in the polymer, environmental monitoring, and regulatory compliance sectors who require precise measurement and traceability of phthalate compounds.

Application

• Internal Standard for Mass Spectrometry (GC-MS, LC-MS): Primary application for the accurate quantification of DINP and related phthalates in complex matrices.
• Polymer Plasticizer Research: Used in migration studies, degradation analysis, and formulation development for PVC and other polymers.
• Environmental Analysis: Critical for tracing and quantifying phthalate contamination in water, soil, and air samples.
• Consumer Product Safety Testing: Enables precise measurement of phthalate levels in toys, food packaging, and medical devices to ensure regulatory compliance (e.g., REACH, CPSIA).
• Biomedical & Toxicological Studies: Facilitates metabolic pathway tracing and pharmacokinetic studies of phthalate exposure.
• Method Development & Validation: Serves as a stable, non-interfering reference compound to establish and calibrate analytical protocols.
