Description

Norfentanyl-D5 Oxalate CAS NO 1211527-23-9 is a stable isotope-labeled internal standard, specifically a deuterated analog of the fentanyl metabolite norfentanyl. This compound is essential for ensuring the accuracy and reliability of quantitative analysis in forensic and clinical toxicology. It is primarily required by analytical laboratories, pharmaceutical researchers, and forensic scientists for use in mass spectrometry-based assays, including LC-MS/MS and GC-MS, for the precise detection and quantification of fentanyl and its metabolites.

Application

• Internal Standard for Bioanalysis: Critical for quantitative LC-MS/MS and GC-MS methods in pharmacokinetic and toxicokinetic studies.
• Forensic Toxicology: Used as a reference standard in the confirmation and quantification of fentanyl and norfentanyl in biological matrices (e.g., blood, urine, hair).
• Clinical Research: Supports studies on drug metabolism, abuse potential, and therapeutic drug monitoring for fentanyl.
• Pharmaceutical Development: Aids in the analytical method development and validation for fentanyl-related drug products and metabolites.
• Reference Material Manufacturing: Serves as a certified component in the production of high-purity reference standards and quality control materials.
