Description

Di-n-Pentyl Phthalate-D4 is a deuterium-labeled internal standard used for precise quantitative analysis in mass spectrometry. This high-purity compound is essential for researchers and quality control laboratories requiring accurate calibration and method validation. It is primarily utilized in the environmental testing, polymer research, and analytical chemistry sectors where trace-level detection of phthalate compounds is critical.

Application

• Internal Standard for GC/MS and LC-MS/MS: Used for the accurate quantification of di-n-pentyl phthalate and related phthalate esters in complex matrices.
• Environmental Analysis: Critical for testing water, soil, and air samples for phthalate contamination as per EPA and other international regulatory methods.
• Polymer and Plasticizer Research: Serves as a deuterated tracer in studies investigating the migration, leaching, and degradation of plasticizers from polymer materials.
• Food Safety and Packaging Testing: Employed in methods to detect phthalate migration from packaging materials into foodstuffs.
• Clinical and Toxicological Studies: Used in biomonitoring to measure phthalate metabolite levels in biological fluids with high precision.
• Method Development and Validation: Provides a stable isotopic reference for developing robust analytical protocols in accredited laboratories.
