Description

Chloroform (13C) is a stable isotope-labeled analog of chloroform, where the central carbon atom is the carbon-13 (13C) isotope. This product is essential for advanced analytical and research applications where precise molecular tracking and quantification are required. It is primarily used by analytical laboratories, pharmaceutical R&D departments, and academic research institutions engaged in nuclear magnetic resonance (NMR) spectroscopy, mass spectrometry, and metabolic studies.

Application

• Internal standard and reference material for quantitative NMR spectroscopy and mass spectrometry (GC-MS, LC-MS).
• Tracer compound in metabolic pathway research and environmental fate studies.
• Solvent for specialized isotopic labeling synthesis in pharmaceutical and chemical research.
• Calibration standard for analytical instrument validation and method development.
• Critical reagent in the development and quality control of active pharmaceutical ingredients (APIs) and other fine chemicals.
• Use in geochemical and forensic analysis as a stable isotopic marker.

Quality Control

Our Chloroform (13C) is produced and handled under strict quality management protocols to ensure exceptional isotopic and chemical purity. Each batch is accompanied by a comprehensive Certificate of Analysis (COA) detailing isotopic enrichment, chemical purity, and solvent residue levels. We adhere to relevant standards for high-purity reagents to ensure reliable performance in sensitive analytical applications.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, well-ventilated place away from strong acids and organic solvents. Recommended storage temperature is 2-8°C to maximize stability. Keep container tightly sealed when not in use to prevent evaporation and moisture absorption.
