Description

Diethyl Phthalate-D14 is a deuterated analog of diethyl phthalate, where all hydrogen atoms are replaced by deuterium. This high-purity, isotopically labeled compound is essential for applications requiring precise analytical tracking and minimal background interference. It is primarily used by researchers and quality control laboratories in the pharmaceutical, environmental, and material science industries for use as an internal standard in mass spectrometry and NMR spectroscopy.

Application

• Internal Standard for Mass Spectrometry (MS): Provides a stable, non-interfering reference for the accurate quantification of phthalates and related compounds in complex matrices.
• NMR Spectroscopy Solvent & Reference: Serves as a deuterated solvent or chemical shift reference in nuclear magnetic resonance studies due to its distinct spectral properties.
• Pharmaceutical Metabolism & Pharmacokinetic Studies: Used as a tracer to study the absorption, distribution, metabolism, and excretion (ADME) of phthalate esters in biological systems.
• Environmental Analysis: Enables precise monitoring and tracing of phthalate plasticizer levels and their degradation pathways in environmental samples.
• Polymer & Material Science Research: Acts as a labeled additive to study migration, leaching, and interaction dynamics of plasticizers within polymer matrices.
• Forensic & Toxicological Analysis: Supports high-accuracy detection and confirmation of phthalate exposure in forensic and clinical toxicology.
