Description

Ethyl Propargylate-13C3 is a stable isotope-labeled analog of ethyl propargylate, where three carbon atoms are replaced with the carbon-13 isotope. This compound is a critical reagent in advanced analytical chemistry, enabling precise quantification and metabolic pathway tracing in complex biological and chemical systems. It is primarily utilized by research institutions and pharmaceutical companies engaged in the development of new chemical entities and life science research, where accurate mass spectrometry and NMR studies are paramount.

Application

• Internal Standard for Mass Spectrometry (MS): Serves as a quantitative internal standard in GC-MS and LC-MS analyses for the accurate measurement of unlabeled ethyl propargylate or related metabolites.
• Metabolic Pathway Tracing: Used in isotopic labeling studies to investigate biochemical pathways and reaction mechanisms in pharmaceutical and agrochemical research.
• NMR Spectroscopy: Acts as a valuable probe in Nuclear Magnetic Resonance (NMR) spectroscopy due to the distinct signal of the 13C nuclei, aiding in structural elucidation.
• Pharmaceutical R&D: Employed in the discovery and development stages of new drugs for pharmacokinetic (PK) and absorption, distribution, metabolism, and excretion (ADME) studies.
• Chemical Synthesis Intermediate: Functions as a labeled building block for the synthesis of more complex 13C-labeled molecules for research purposes.
