Description

Bis(2-Propylheptyl) Phthalate-D4 is a deuterium-labeled internal standard of the high-molecular-weight phthalate plasticizer, di-2-propylheptyl phthalate (DPHP). This compound is essential for precise quantitative analysis in gas chromatography-mass spectrometry (GC-MS) and liquid chromatography-mass spectrometry (LC-MS) applications, providing unmatched accuracy by correcting for analyte loss during sample preparation and instrument variability. It is a critical tool for analytical laboratories in the polymer, environmental monitoring, and consumer product safety sectors requiring definitive measurement of phthalate levels.

Application

• Internal Standard for GC-MS/LC-MS Analysis: Primary use as a quantitative reference standard for the accurate determination of DPHP and related phthalates in complex matrices.
• Polymer & Plasticizer Research: Enables precise study of plasticizer migration, leaching, and degradation kinetics from PVC and other polymer formulations.
• Environmental & Food Safety Testing: Critical for regulatory compliance testing to detect and quantify phthalate contamination in water, soil, food packaging, and consumer goods.
• Biomedical & Toxicological Studies: Used in metabolism, pharmacokinetic, and exposure assessment studies to track phthalate esters in biological samples.
• Quality Control in Manufacturing: Serves as a benchmark in quality assurance protocols for producers of plasticizers and plastic products.
• Method Development & Validation: Indispensable for developing, optimizing, and validating robust analytical methods in accredited laboratories.

Quality Control

Our deuterated standards are produced under strict quality management systems. Each batch of Bis(2-Propylheptyl) Phthalate-D4 undergoes rigorous analysis by NMR, MS, and HPLC to confirm isotopic purity, chemical purity, and identity. Certificates of Analysis (COA) are provided, detailing batch-specific results for isotopic enrichment (typically >98 atom % D), chemical purity, and suitability for use as an internal standard. Our quality commitment ensures reliability for your most demanding analytical applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Keep away from strong acids and organic solvents. For long-term stability, store under an inert atmosphere if the container is frequently opened.
