Description

Maleic Anhydride-13C4 is a stable isotope-labeled analog of maleic anhydride, where all four carbon atoms are the carbon-13 isotope. This product is essential for advanced analytical and research applications requiring precise molecular tracking and quantification. It is primarily used by researchers and scientists in pharmaceutical development, metabolic studies, and environmental analysis who require high-purity isotopic standards for mass spectrometry and NMR spectroscopy.

Application

• Internal standard for the accurate quantification of maleic anhydride and related compounds via LC-MS (Liquid Chromatography-Mass Spectrometry) and GC-MS.
• Tracer compound in metabolic pathway studies and pharmacokinetic research within the pharmaceutical industry.
• Precursor for synthesizing 13C-labeled polymers and specialty chemicals for advanced material science research.
• Use in NMR (Nuclear Magnetic Resonance) spectroscopy as a chemical shift reference or for mechanistic studies.
• Environmental fate and degradation studies of industrial chemicals, enabling precise tracking of compounds.
• Development and validation of analytical methods in regulatory and quality control laboratories.

Quality Control

Our Maleic Anhydride-13C4 is manufactured under controlled conditions to ensure exceptional isotopic and chemical purity. Each batch undergoes rigorous analytical testing, including NMR and mass spectrometry, to confirm isotopic enrichment and chemical identity. Certificates of Analysis (COA) detailing isotopic purity, chemical purity, and analytical methods are provided with every shipment to support your research and compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept sealed under an inert atmosphere to prevent degradation. Recommended long-term storage at 2-8°C.
