Description

1-Phenyl-D5-Ethanol is a deuterium-labeled analog of 1-phenylethanol, a key chiral building block and intermediate. This compound is specifically valued for its use as an internal standard in quantitative mass spectrometry, enabling precise analytical measurements in complex matrices. It is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and advanced materials sectors who require high-purity, isotopically labeled compounds for metabolic studies, method development, and quality control.

Application

• Internal Standard for LC-MS/MS: Used in quantitative bioanalysis for drug metabolism and pharmacokinetic (DMPK) studies to ensure accurate measurement of analytes.
• Pharmaceutical Research: Serves as a labeled precursor or intermediate in the synthesis of deuterated active pharmaceutical ingredients (APIs) for clinical research.
• Metabolic Pathway Tracing: Employed in mechanistic studies to track metabolic pathways and identify metabolites in biological systems.
• Analytical Method Development: A critical tool for validating analytical methods, particularly in regulated environments requiring high precision and accuracy.
• Chemical Synthesis: Acts as a chiral synthon or building block for the preparation of more complex, labeled organic molecules.
• Environmental and Food Safety Testing: Utilized in residue analysis methods for pesticides, contaminants, and toxins to improve detection reliability.
