Description

1,4-Butane-D8-Dithiol CAS NO 1219805-46-5 is a deuterated analog of 1,4-butanedithiol, where eight hydrogen atoms are replaced with deuterium, making it a valuable isotopically labeled compound. This deuteration provides a stable isotopic marker essential for advanced analytical and research applications, offering enhanced precision in spectroscopic and mechanistic studies. It is primarily required by researchers and manufacturers in the pharmaceutical, agrochemical, and material science industries for use as an internal standard, tracer, or building block in the synthesis of labeled compounds.

Application

• As an internal standard in quantitative mass spectrometry (MS) and nuclear magnetic resonance (NMR) analysis for accurate measurement of its non-deuterated counterpart.
• As a deuterated building block in organic synthesis for the preparation of isotopically labeled pharmaceuticals and active ingredients for metabolic and pharmacokinetic studies.
• In mechanistic research to trace reaction pathways and investigate chemical and biological processes using isotopic labeling techniques.
• For the development and calibration of analytical methods in regulatory and quality control laboratories requiring high specificity and accuracy.
• In material science research for studying the properties and behaviors of polymers or other materials where deuterium labeling can reduce background interference.
