Description

6-Desamino 6-Chloro Etravirine-13C3 is a stable isotope-labeled analog of the HIV-1 non-nucleoside reverse transcriptase inhibitor (NNRTI) Etravirine, specifically labeled with three carbon-13 atoms. This compound is a critical reference standard and intermediate for the development and validation of highly sensitive and accurate bioanalytical methods, such as LC-MS/MS, used in pharmacokinetic and drug metabolism studies. It is essential for pharmaceutical R&D laboratories, contract research organizations (CROs), and manufacturers requiring internal standards for precise quantification of Etravirine and its metabolites in biological matrices.

Application

• Internal Standard for Bioanalysis: Serves as a stable isotope-labeled internal standard (SIL-IS) in quantitative LC-MS/MS assays for Etravirine in plasma, serum, and other biological fluids.
• Drug Metabolism and Pharmacokinetics (DMPK): Used in ADME (Absorption, Distribution, Metabolism, Excretion) studies to track and quantify the parent drug and its metabolites with high specificity.
• Clinical Research: Enables accurate therapeutic drug monitoring (TDM) and bioavailability/bioequivalence studies for Etravirine formulations.
• Pharmaceutical Impurity Profiling: Acts as a reference material for identifying and quantifying related substances and degradation products during drug substance and product development.
• Regulatory Submissions: Supports method validation data packages required by regulatory agencies like the FDA and EMA for new drug applications (NDAs).
• Metabolite Synthesis & Identification: A key synthetic intermediate for preparing isotopically labeled metabolites of Etravirine for structural confirmation.
