Description

p-Chlororesorcinol-13C6 is a stable isotope-labeled analog of p-chlororesorcinol, where all six carbon atoms are the carbon-13 isotope. This compound is essential as a high-purity internal standard and tracer in quantitative analytical chemistry, particularly for mass spectrometry (MS) and nuclear magnetic resonance (NMR) studies. It is primarily required by research institutions, pharmaceutical development labs, and analytical service providers working on method development, metabolic pathway analysis, and pharmacokinetic studies to ensure accurate and reliable quantitative data.

Application

• Internal Standard for LC-MS/MS: Used as a quantitative reference standard in liquid chromatography-tandem mass spectrometry for the accurate analysis of p-chlororesorcinol and related compounds in complex matrices.
• Metabolic Tracer Studies: Employed in pharmaceutical and biochemical research to trace metabolic pathways and degradation products due to its isotopic labeling.
• NMR Spectroscopy: Serves as a valuable tool in nuclear magnetic resonance spectroscopy for structural elucidation and mechanistic studies.
• Method Development & Validation: Critical for developing and validating sensitive and specific analytical methods in quality control and research laboratories.
• Environmental Analysis: Can be used as a tracer in environmental fate studies to monitor the degradation and movement of chlorinated phenolic compounds.
• Pharmaceutical Impurity Profiling: Aids in the identification and quantification of process-related impurities and degradants in active pharmaceutical ingredients (APIs).

Quality Control

Our products undergo rigorous quality testing to ensure compliance with industry standards. Each batch of p-Chlororesorcinol-13C6 is characterized to confirm chemical identity, isotopic purity, and chemical purity. Certificates of Analysis (COA) are available upon request and provide detailed results for parameters such as assay (by HPLC), isotopic enrichment, and related substances.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its light-sensitive nature and tendency to be easily oxidized, it is recommended to store the material under an inert atmosphere (e.g., nitrogen or argon) for long-term stability, especially after opening the primary container. Keep away from heat and incompatible materials.
