Description

4-Aminophenol-13C6 is a stable isotope-labeled analog of 4-aminophenol, where all six carbon atoms are the carbon-13 isotope. This compound is essential as a high-purity internal standard and reference material in quantitative mass spectrometry, ensuring analytical accuracy and traceability. It is primarily required by pharmaceutical research laboratories, contract research organizations (CROs), and diagnostic manufacturers for applications in drug metabolism studies, pharmacokinetics, and bioanalytical method development.

Application

• Internal Standard for LC-MS/MS in bioanalysis and clinical research.
• Quantitative reference material for pharmaceutical impurity profiling and assay development.
• Metabolite tracking and drug metabolism studies (DMPK) using stable isotope dilution techniques.
• Calibration standard in environmental or forensic analysis for phenolic compound detection.
• Use in the synthesis of carbon-13 labeled drug molecules or complex biochemical probes.
• Quality control and method validation in analytical laboratories to meet GLP/GMP standards.

Quality Control

Our 4-Aminophenol-13C6 is manufactured under controlled conditions to ensure exceptional isotopic and chemical purity, critical for sensitive analytical applications. Each batch is supported by a comprehensive Certificate of Analysis (COA) detailing isotopic enrichment (typically >99 atom % 13C), chemical purity by HPLC, and identity confirmation. We adhere to stringent quality protocols suitable for research and development under ISO-guided standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at 15-25°C. This material is light-sensitive and easily oxidized; for long-term storage, consider under an inert atmosphere such as argon or nitrogen to maintain stability and purity.
