Description

Di-n-Propyl Phthalate-3,4,5,6-D4 is a deuterium-labeled isotopologue of di-n-propyl phthalate, a compound of significant interest in analytical and research chemistry. This labeled standard is essential for applications requiring high precision and minimal interference from background signals, such as quantitative mass spectrometry. It is primarily utilized by analytical laboratories, environmental testing facilities, and research institutions engaged in method development, internal standardization, and trace-level quantification of phthalate compounds.

Application

• Internal Standard for Mass Spectrometry (MS): Serves as a critical reference compound in GC-MS and LC-MS/MS analyses for the accurate quantification of unlabeled phthalates in complex matrices.
• Method Development and Validation: Used by analytical chemists to develop, optimize, and validate sensitive detection methods for phthalate esters.
• Environmental Analysis: Employed in tracing and quantifying phthalate contaminants in water, soil, and air samples with high accuracy.
• Metabolic and Pharmacokinetic Studies: Acts as a stable-isotope tracer in biomedical and toxicological research to study the absorption, distribution, metabolism, and excretion (ADME) of phthalates.
• Quality Control and Assurance: Provides a reliable benchmark for ensuring the accuracy and precision of analytical results in contract research organizations (CROs) and quality control labs.
• Food and Consumer Product Safety Testing: Facilitates the detection and measurement of phthalate migration from packaging materials into foodstuffs and other consumer goods.
