Description

Phenylacetic-D7 Acid CAS NO 65538-27-4 is a deuterated analog of phenylacetic acid, where seven hydrogen atoms are replaced by deuterium, a stable isotope of hydrogen. This high isotopic purity makes it an essential internal standard and tracer in quantitative mass spectrometry, ensuring unparalleled accuracy in analytical measurements. It is a critical reagent for researchers and quality control laboratories in the pharmaceutical, agrochemical, and forensic science industries, where precise quantification of metabolites, impurities, or environmental contaminants is required.

Application

• Internal Standard for LC-MS/MS and GC-MS analysis in bioanalytical and pharmacokinetic studies.
• Deuterated tracer in metabolic pathway research and stable isotope labeling experiments.
• Quantitative analysis of phenylacetic acid and its derivatives in pharmaceutical quality control.
• Forensic analysis and toxicology for the precise measurement of specific compounds.
• Environmental monitoring to trace and quantify chemical pollutants.
• Synthesis of more complex deuterated compounds for use as advanced analytical standards.
