Chloromethane-13C
Chloromethane-13C (CAS: 19961-13-8), with the formula <sup>13</sup>CH3Cl and a molecular weight of 51.48 g/mol, is a stable isotope-labelled version of chloromethane. This compound serves as a critical reagent in chemical synthesis and research, particularly in studies requiring isotopic tracing or as a precursor in the development of complex organic molecules and labelled compounds for various analytical applications.
- IUPAC
- Methyl-13C chloride
- Synonyms
- Methyl-13C chloride
Isotopic Labelling
Utilised in research for isotopic enrichment studies, allowing for precise tracking of molecules in chemical and biological pathways. Its 13C label provides a unique spectroscopic signature for analysis.
Chemical Synthesis
Serves as a methylating agent in organic synthesis, especially when isotopic incorporation is desired for mechanistic studies or the preparation of labelled intermediates. Its reactivity is comparable to non-isotopically labelled chloromethane.
Analytical Standards
Can be employed as an internal standard in mass spectrometry or other analytical techniques where a known concentration of an isotopically distinct compound is required for quantification or calibration.
