Description

Pentaerythritol-13C CAS NO 334974-06-0 is a stable isotope-labeled analog of pentaerythritol, where the central carbon atom is the carbon-13 (13C) isotope. This compound is essential as a high-purity internal standard and tracer in quantitative nuclear magnetic resonance (qNMR) spectroscopy and mass spectrometry. It is critically required by analytical laboratories and research institutions in the pharmaceutical, agrochemical, and advanced materials sectors for precise metabolic studies, method validation, and ensuring regulatory compliance in quantification.

Application

• Quantitative NMR (qNMR) Internal Standard: Serves as a primary standard for the accurate quantification of organic compounds and impurities in pharmaceutical active ingredients and complex mixtures.
• Mass Spectrometry Tracer: Used in stable isotope dilution mass spectrometry (SID-MS) for highly accurate and sensitive quantification of metabolites, drugs, and environmental contaminants.
• Metabolic Pathway Research: Acts as a labeled precursor or tracer to study biosynthesis pathways and metabolic fluxes in biological systems.
• Pharmaceutical R&D: Critical for method development and validation in drug discovery, pharmacokinetics, and impurity profiling to meet ICH guidelines.
• Polymer Science Studies: Employed in the research of alkyd resins and polyurethanes to trace monomer incorporation and polymer degradation mechanisms.
• Certified Reference Material (CRM): Used in the preparation of certified reference materials for ensuring measurement traceability and laboratory accreditation (ISO/IEC 17025).

Quality Control

Our Pentaerythritol-13C is manufactured under strict quality control protocols to ensure exceptional isotopic and chemical purity, essential for analytical accuracy. Each batch is supported by a comprehensive Certificate of Analysis (COA) detailing isotopic enrichment (typically >99 atom % 13C), chemical purity, and identity confirmation. We adhere to relevant standards for high-purity reference materials to support GLP and ISO-compliant laboratories.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and must be kept under anhydrous conditions to maintain stability and purity. For long-term storage, consider desiccant or an inert atmosphere.
