Description

Maleic Anhydride-1-13C is a stable isotope-labeled derivative of maleic anhydride, where a carbon-13 atom is incorporated at a specific position. This precise labeling is critical for advanced analytical and research applications, providing a distinct molecular signature for tracking and quantification. It is an essential tool for scientists and manufacturers in the pharmaceutical, agrochemical, and material science industries who require high-fidelity tracers for metabolic studies, reaction mechanism elucidation, and quality control of complex chemical processes.

Application

• Isotope-Labeled Analytical Standards: Used as an internal standard in quantitative mass spectrometry (MS) and nuclear magnetic resonance (NMR) spectroscopy for accurate measurement of maleic anhydride or its derivatives in complex matrices.
• Metabolic Pathway Tracing: Employed in pharmaceutical and biochemical research to study the metabolic fate and degradation pathways of compounds derived from maleic anhydride.
• Mechanistic Studies: Essential for elucidating detailed reaction mechanisms in organic synthesis and polymer chemistry, allowing researchers to track the incorporation of specific carbon atoms.
• Polymer Research & Development: Used in the synthesis of specifically labeled polymers (e.g., styrene-maleic anhydride copolymers) for advanced material property analysis and degradation studies.
• Agrochemical Research: Facilitates the study of environmental fate, biodegradation, and metabolic pathways of agrochemicals synthesized from maleic anhydride precursors.
• Quality Control & Forensic Analysis: Serves as a high-purity reference material to validate analytical methods and ensure the accuracy of purity assays in industrial and regulatory settings.

Quality Control

Every batch of Maleic Anhydride-1-13C is manufactured and analyzed under strict quality systems to ensure exceptional isotopic and chemical purity. Our products undergo rigorous quality testing, including isotopic enrichment analysis by NMR and quantitative purity assessment by GC or HPLC, to ensure compliance with research-grade standards. Certificates of Analysis (COA) detailing batch-specific data for isotopic purity, chemical purity, and identity are provided and available upon request.

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 (e.g., nitrogen or argon) after opening to prevent hydrolysis. Recommended long-term storage temperature is 2-8°C.
