Description

Cyclopentanone-2,2,5,5-D4 is a deuterated analog of cyclopentanone, where four hydrogen atoms are replaced with deuterium, a stable isotope of hydrogen. This isotopic labeling is critical for applications requiring precise molecular tracking and reduced signal interference in spectroscopic analysis. It is an essential reagent for researchers and manufacturers in the fields of analytical chemistry, pharmaceutical development, and materials science, where it serves as a valuable internal standard and a building block for labeled compounds.

Application

• Internal Standard for Quantitative NMR (qNMR) and Mass Spectrometry (MS) analysis.
• Deuterated Solvent and Reagent in Fourier-Transform Infrared (FTIR) and Nuclear Magnetic Resonance (NMR) spectroscopy.
• Precursor for the synthesis of deuterium-labeled pharmaceutical intermediates and active pharmaceutical ingredients (APIs).
• Tracer compound in metabolic pathway studies and reaction mechanism elucidation.
• Starting material for producing specialty polymers and advanced materials with modified properties.
• Component in the development and calibration of analytical instruments and methodologies.
