Description

Phenyl(Acetic Acid-1-13C) is a stable isotope-labeled derivative of phenylacetic acid, where the carbonyl carbon is enriched with the carbon-13 isotope. This precise labeling is critical for applications requiring high sensitivity and accurate molecular tracking, such as in quantitative mass spectrometry. It is an essential building block and internal standard for researchers and manufacturers in the pharmaceutical, agrochemical, and advanced material sectors who require definitive analytical data and metabolic pathway elucidation.

Application

• Quantitative Mass Spectrometry (MS) & NMR Spectroscopy: Serves as a crucial internal standard for the accurate quantification of phenylacetic acid and related compounds in complex biological and chemical matrices.
• Pharmaceutical Research & Development: Used in drug metabolism and pharmacokinetics (DMPK) studies to trace metabolic pathways and improve the analytical precision of bioassays for new active pharmaceutical ingredients (APIs).
• Agrochemical Analysis: Employed as a labeled standard in environmental and residue analysis for pesticides and plant growth regulators derived from or related to phenylacetic acid.
• Biochemical Tracing: Facilitates the study of biosynthetic pathways in microbiology and plant biology, allowing researchers to track the incorporation of specific carbon atoms.
• Chemical Synthesis: Acts as a labeled precursor for the synthesis of more complex carbon-13 labeled compounds for research and diagnostic purposes.
