Description

p-Cresol-D7 is a deuterium-labeled isotopologue of p-cresol, a key phenolic compound. This stable isotope-labeled standard is essential for ensuring accuracy and reliability in quantitative analytical methods, particularly mass spectrometry. It is primarily used by researchers and quality control laboratories in the pharmaceutical, environmental, and metabolomics fields for precise internal standardization and tracer studies.

Application

• Internal Standard for Mass Spectrometry (MS): Used for the accurate quantification of p-cresol and related metabolites in complex biological matrices like blood, urine, and tissue samples.
• Metabolomics and Biomarker Research: Enables precise tracking and measurement of metabolic pathways involving phenolic compounds in disease state studies.
• Pharmaceutical Analysis: Critical for drug metabolism and pharmacokinetic (DMPK) studies to monitor the formation and clearance of phenolic metabolites.
• Environmental Testing: Serves as a reference standard in the analysis of environmental pollutants, such as cresols, in water and soil samples.
• Deuterated Tracer Studies: Utilized in mechanistic studies to elucidate biochemical pathways and degradation processes due to its isotopic label.
• Quality Control & Method Development: Essential for developing, validating, and ensuring the precision of analytical methods in contract research organizations (CROs) and testing laboratories.
