Description

Methyl-13C Phenyl Sulfone is a stable isotope-labeled compound where the methyl group is enriched with carbon-13 (13C). This product is essential for applications requiring precise internal standards and metabolic pathway tracing in advanced analytical research. It is primarily utilized by pharmaceutical R&D laboratories, contract research organizations (CROs), and academic institutions engaged in drug metabolism and pharmacokinetics (DMPK) studies, mass spectrometry, and NMR spectroscopy.

Application

• Internal standard for the quantitative analysis of sulfone derivatives and related metabolites via LC-MS (Liquid Chromatography-Mass Spectrometry) and GC-MS.
• Tracer compound in drug metabolism studies (DMPK) to elucidate biotransformation pathways.
• Critical reagent in the synthesis of 13C-labeled complex molecules for use as analytical probes.
• Reference material for NMR (Nuclear Magnetic Resonance) spectroscopy due to its distinct 13C signal.
• Use in environmental fate studies and agrochemical research involving sulfone compounds.
• Building block for labeled pharmaceutical intermediates in pre-clinical and clinical research.
