Description

5-Ethyl-2-Pyridine Ethanol-D4 is a deuterated derivative of 5-ethyl-2-pyridineethanol, where four hydrogen atoms are replaced with deuterium, serving as a stable isotope-labeled internal standard. This high-purity compound is critical for ensuring accuracy and reliability in quantitative mass spectrometry and nuclear magnetic resonance (NMR) spectroscopy. It is primarily utilized by analytical chemists and researchers in the pharmaceutical, agrochemical, and metabolomics sectors for method development, validation, and precise quantification of target analytes.

Application

• Internal Standard for LC-MS/MS: Essential for accurate quantification of 5-ethyl-2-pyridineethanol and related metabolites in complex biological matrices like plasma, urine, and tissue homogenates.
• Metabolomics & Pharmacokinetic Studies: Enables precise tracking of drug absorption, distribution, metabolism, and excretion (ADME) in preclinical and clinical research.
• Deuterated Reference Material: Used in NMR spectroscopy as a chemical shift reference or for mechanistic studies in synthetic chemistry.
• Pharmaceutical Impurity Profiling: Aids in the identification and quantification of process-related impurities and degradation products during drug development.
• Agrochemical Research: Supports the analysis of pesticide metabolites and environmental fate studies.
• Forensic & Clinical Toxicology: Facilitates the reliable detection and measurement of specific biomarkers or xenobiotics.

Quality Control

Our 5-Ethyl-2-Pyridine Ethanol-D4 is manufactured under strict quality systems to ensure the high isotopic purity and chemical integrity required for analytical applications. Each batch is characterized by advanced spectroscopic and chromatographic techniques, including NMR, HPLC, and mass spectrometry. A comprehensive Certificate of Analysis (COA) detailing isotopic enrichment (e.g., D4 > 98 atom % D), chemical purity, and identity confirmation is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container should be kept sealed under an inert atmosphere (e.g., nitrogen or argon) after initial opening to prevent degradation and maintain isotopic integrity.
