Description

Propyl-D7 Paraben is a deuterium-labeled analog of propylparaben, a widely used synthetic preservative. This stable isotope-labeled compound is essential for advanced analytical techniques, providing unmatched precision in quantitative analysis and metabolic studies. It is a critical standard for researchers and quality control laboratories in the pharmaceutical, cosmetic, and food industries who require definitive identification and accurate measurement of propylparaben.

Application

• Internal Standard for Quantitative Analysis: Used as a deuterated internal standard in LC-MS/MS and GC-MS methods for the precise quantification of propylparaben in complex matrices.
• Metabolic Pathway Tracing: Employed in pharmacokinetic and metabolism studies to track the absorption, distribution, metabolism, and excretion (ADME) of parabens.
• Method Development & Validation: Serves as a critical reference material for developing and validating robust analytical methods in regulatory and research settings.
• Quality Control & Assurance: Used in pharmaceutical and cosmetic QC labs to ensure the accuracy of preservative content analysis and batch-to-batch consistency.
• Environmental & Food Safety Testing: Applied in the analysis of propylparaben residues in environmental samples, food products, and beverages.
• Stable Isotope Dilution Assays: Enables highly accurate and reproducible results by correcting for analyte loss during sample preparation in isotope dilution mass spectrometry.
