Description

Bromomethane-13C CAS NO 51624-21-6 is a stable isotope-labeled derivative of methyl bromide, where the carbon atom is the carbon-13 (13C) isotope. This isotopic purity makes it an essential tool for advanced analytical research and method development, providing a critical internal standard for precise quantification. It is primarily required by analytical laboratories, research institutions, and chemical manufacturers engaged in environmental testing, metabolic studies, and the synthesis of labeled compounds for use as tracers.

Application

• Used as an internal standard in Gas Chromatography-Mass Spectrometry (GC-MS) and Liquid Chromatography-Mass Spectrometry (LC-MS) for the accurate quantification of methyl bromide in environmental and agricultural samples.
• Critical reagent in metabolic pathway tracing and pharmacokinetic studies within pharmaceutical and biochemical research.
• Employed as a labeled precursor in the synthesis of more complex 13C-labeled organic compounds for use as analytical tracers.
• Facilitates method development and validation in analytical chemistry, ensuring regulatory compliance for residue analysis.
• Applied in atmospheric chemistry research to study the fate and transport of halogenated volatile organic compounds.
• Supports quality control processes in industries requiring high-purity methyl bromide, by serving as a reference material.
