Description

4-Chlorophenyl-1,2-Epoxybutane-D5 is a deuterated analog of 4-chlorophenyl-1,2-epoxybutane, where five hydrogen atoms are replaced with deuterium, a stable isotope of hydrogen. This deuteration is critical for applications requiring internal standards in mass spectrometry, enabling precise quantification and reducing analytical interference. This high-purity compound is essential for researchers and manufacturers in the pharmaceutical, agrochemical, and analytical chemistry sectors who require reliable, isotopically labeled materials for method development and quality control.

Application

• As a deuterated internal standard for the accurate quantification of its non-deuterated counterpart in complex matrices using LC-MS or GC-MS.
• In metabolic and pharmacokinetic studies within pharmaceutical R&D to trace the fate of drug molecules and their metabolites.
• For analytical method development and validation in quality control laboratories to ensure accuracy, precision, and regulatory compliance.
• As a key synthetic intermediate in the preparation of other deuterium-labeled compounds for research purposes.
• In environmental analysis to study the degradation and behavior of chlorinated organic compounds.
• For mechanistic studies in organic chemistry, utilizing the kinetic isotope effect to elucidate reaction pathways.
