Description

p-Cresol-Ring-Ul-14C is a carbon-14 radiolabeled isotopologue of p-cresol, a key phenolic compound. This labeled version is essential for advanced metabolic, environmental, and pharmacokinetic studies where precise tracking of the phenolic ring is required. It is a critical tool for researchers and quality control specialists in the pharmaceutical, agrochemical, and environmental science industries.

Application

• Tracer Studies in Metabolism: Used to investigate the metabolic pathways and biotransformation of p-cresol and related compounds in biological systems.
• Environmental Fate Analysis: Employed in studies to track the degradation, adsorption, and transport of phenolic pollutants in soil and water.
• Drug Metabolism and Pharmacokinetics (DMPK): Serves as a radiolabeled tracer in ADME (Absorption, Distribution, Metabolism, Excretion) studies for drug candidates containing phenolic structures.
• Synthesis of Labeled Compounds: Acts as a building block for the synthesis of more complex carbon-14 labeled molecules for research and regulatory submission packages.
• Analytical Method Development: Used as an internal standard or reference material in developing sensitive analytical methods like LC-MS/MS for phenolic compounds.
