Description

Methylene Chloride (13C) is a stable isotope-labeled analog of dichloromethane, where the central carbon atom is 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 analytical laboratories, pharmaceutical R&D departments, and academic research institutions engaged in metabolic studies, environmental analysis, and NMR spectroscopy.

Application

• Nuclear Magnetic Resonance (NMR) Spectroscopy: Serves as a crucial solvent and internal standard for chemical shift referencing and quantitative analysis.
• Mass Spectrometry (MS) & LC-MS: Used as a labeled internal standard for the accurate quantification of dichloromethane and related compounds in complex matrices.
• Metabolic Pathway Tracing: Acts as a tracer in biochemical and pharmacological research to study drug metabolism and environmental fate.
• Environmental Analysis: Employed in method development and as a calibration standard for monitoring volatile organic compounds (VOCs) in air and water.
• Pharmaceutical Research: Facilitates drug discovery and development processes, including stability testing and impurity profiling using isotope dilution techniques.
• Chemical Synthesis: Used in specialized synthetic routes where a 13C-labeled building block is required for mechanistic studies or to produce labeled target molecules.

Quality Control

Our Methylene Chloride (13C) is produced and handled under stringent quality management systems. Each batch is analyzed to ensure high chemical and isotopic purity, with specifications typically covering isotopic enrichment, chemical assay, and key impurities. Certificates of Analysis (COA) detailing batch-specific results from advanced techniques like NMR, GC-MS, and IR are provided to guarantee traceability and compliance with your research or analytical requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated area away from heat sources and incompatible materials such as strong bases and active metals. Due to its highly volatile nature, ensure containers are kept upright and sealed when not in use. Recommended storage temperature is 2-25°C.
