Deuterium sulfide
Deuterium sulfide (CAS: 13536-94-2), a deuterated analogue of hydrogen sulfide with the formula D2S, is a colorless gas with a molecular weight of 36.09 g/mol. Possessing a distinct odor, it finds utility in specialized chemical synthesis and as a stable isotope labelled compound. Its high isotopic purity makes it valuable for research requiring precise isotopic tracing. Deuterium sulfide is handled as a hazardous material due to its flammability and toxicity.
Chemical Synthesis
Deuterium sulfide serves as a valuable reagent in organic and inorganic synthesis, particularly where isotopic labelling is required for mechanistic studies or reaction pathway elucidation.
Isotope Labelling
As a stable isotope, D2S is employed in research settings for labelling purposes, aiding in the tracking and analysis of chemical processes and biological systems.
Research and Development
This compound is utilised in various R&D activities, especially in areas investigating sulfur chemistry or requiring deuterated compounds for spectroscopic or mass spectrometric analysis.
