Description

4-Amino-2,3,5,6-Tetradeuterio-n-Quinoxalin-2-Ylbenzenesulfonamide is a deuterated derivative of a quinoxaline-based benzenesulfonamide, a compound class of significant interest in advanced research and development. This deuterated analog is specifically designed for use as an internal standard or a labeled precursor in analytical and synthetic chemistry, offering enhanced precision in mass spectrometry and metabolic studies. It is primarily utilized by pharmaceutical R&D teams, contract research organizations (CROs), and analytical laboratories engaged in drug discovery, pharmacokinetics, and stable isotope labeling.

Application

• Internal Standard for LC-MS/MS Analysis: Used as a deuterium-labeled internal standard for the accurate quantification of its non-deuterated counterpart in complex biological matrices.
• Metabolic Pathway Tracing: Employed in drug metabolism and pharmacokinetics (DMPK) studies to track and identify metabolites using mass spectrometry.
• Isotope Dilution Mass Spectrometry (IDMS): Serves as a critical component in high-precision analytical methods for clinical research and bioanalysis.
• Pharmaceutical Reference Standard: Acts as a certified reference material for method development, validation, and quality control in analytical laboratories.
• Synthetic Chemistry Intermediate: Used as a building block in the synthesis of more complex deuterated molecules for research purposes.
• Proteomics and Biomarker Research: Facilitates relative and absolute quantification in proteomic studies and biomarker discovery.
