Description

3-(Cyclohexylamino)-1-Propanesulfonic-D17 Acid is a deuterated analog of the common biological buffer CAPS, where seventeen hydrogen atoms are replaced with the stable isotope deuterium. This deuteration is critical for applications requiring reduced interference from proton signals, such as in advanced Nuclear Magnetic Resonance (NMR) spectroscopy and mass spectrometry studies. It is primarily utilized by research scientists and process developers in pharmaceutical R&D, analytical chemistry, and metabolic research where isotopic labeling is necessary for precise molecular tracking and structural elucidation.

Application

• Internal standard or reference material in quantitative mass spectrometry (MS) and liquid chromatography-mass spectrometry (LC-MS) for pharmaceutical analysis.
• Deuterated buffer component for NMR spectroscopy to minimize background proton signals and improve spectral clarity in structural biology and organic chemistry research.
• Tracer compound in metabolic pathway studies and drug metabolism and pharmacokinetics (DMPK) research within preclinical development.
• Chemical intermediate in the synthesis of more complex deuterated labeled compounds for use as analytical standards or in specialized material science.
• Component in specialized electrophoresis and capillary electrophoresis buffer systems requiring isotopic stability.

Quality Control

Our deuterated chemicals are produced and tested under strict quality protocols to ensure high isotopic purity and chemical integrity, essential for sensitive analytical applications. Each batch is characterized by advanced techniques including NMR and MS to confirm deuteration level and chemical purity. A comprehensive Certificate of Analysis (COA) detailing isotopic enrichment (atom % D), purity by HPLC, and other critical parameters is provided with every shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This compound is hygroscopic (moisture-sensitive); ensure the container is sealed tightly after each use to prevent degradation from atmospheric moisture. For long-term storage, consider using desiccant in the storage area.
