Description

n-Propyl 4-Hydroxybenzoate--D4 is a deuterium-labeled analog of the common preservative propylparaben, specifically designed for analytical and research applications. This stable isotope-labeled compound is essential for use as an internal standard in mass spectrometry, enabling highly accurate quantitative analysis and method development. It is a critical tool for researchers and quality control laboratories in the pharmaceutical, food safety, and environmental monitoring sectors who require precise measurement of parabens and their metabolites.

Application

• Internal Standard for LC-MS/MS and GC-MS analysis of parabens in complex matrices.
• Quantitative reference material in pharmacokinetic and metabolic stability studies.
• Tracer compound in environmental fate studies and biodegradation research.
• Calibration standard for method validation in regulatory testing for food and cosmetic safety.
• Research reagent for investigating the absorption, distribution, metabolism, and excretion (ADME) of propylparaben.
• Critical component in high-accuracy assays for clinical and forensic toxicology.

Quality Control

Our n-Propyl 4-Hydroxybenzoate--D4 is manufactured under strict quality systems to ensure the high chemical and isotopic purity required for analytical applications. Each batch is supported by a comprehensive Certificate of Analysis (COA) detailing parameters such as isotopic enrichment (atom % D), chemical purity by HPLC, and identity confirmation by NMR and MS. We ensure compliance with relevant standards for high-purity reference materials.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at controlled room temperature (15-25°C). Keep the container tightly sealed to prevent moisture absorption and potential contamination.
