Description

2-Aminoethanol-2-13C CAS NO 637344-08-2 is a stable isotope-labeled analog of monoethanolamine, where the carbon atom at the 2-position is the carbon-13 isotope. This compound is essential for advanced analytical and research applications where precise molecular tracing is required. It is primarily used by researchers and manufacturers in the pharmaceutical, agrochemical, and life science industries for use as an internal standard in mass spectrometry, metabolic pathway studies, and the synthesis of labeled complex molecules.

Application

• Internal standard for the quantitative analysis of ethanolamine and related compounds via GC-MS or LC-MS.
• Tracer compound in metabolic flux analysis and biochemical pathway research.
• Precursor in the synthesis of carbon-13 labeled pharmaceutical intermediates and active ingredients.
• Research reagent for studying the environmental fate and degradation of ethanolamine-based chemicals.
• Key starting material for producing labeled surfactants, corrosion inhibitors, and gas treating agents for research purposes.
• Use in NMR spectroscopy as a tool for structural elucidation and reaction mechanism studies.

Quality Control

Our 2-Aminoethanol-2-13C is produced under controlled conditions to ensure high isotopic and chemical purity, meeting the stringent requirements of research and analytical applications. Each batch is characterized by NMR and mass spectrometry to confirm isotopic enrichment and identity. Certificates of Analysis (COA) detailing isotopic purity, chemical purity, and specific tests are provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); containers must be kept tightly sealed and under an inert atmosphere (e.g., nitrogen) after opening to prevent degradation and absorption of moisture.
