Description

n-Methylpyrrole-D4 is a deuterated isotopologue of n-methylpyrrole, where four hydrogen atoms are replaced by deuterium, a stable hydrogen isotope. This deuteration is critical for applications requiring reduced interference from proton signals, enhancing spectral clarity and analytical precision. It is an essential building block and analytical standard for researchers and manufacturers in the pharmaceutical, agrochemical, and advanced materials sectors, particularly for NMR spectroscopy and mechanistic studies.

Application

• NMR Spectroscopy Internal Standard: Used as a deuterated solvent or reference compound to eliminate solvent proton signals and improve spectral resolution in nuclear magnetic resonance analysis.
• Pharmaceutical Research & Development: Serves as a labeled intermediate in the synthesis of deuterated drug candidates for metabolic stability studies, pharmacokinetic tracing, and patent protection.
• Mechanistic Reaction Studies: Employed as a tracer to elucidate reaction pathways and kinetics in catalytic and organic synthesis research.
• Agrochemical Development: Utilized in creating labeled versions of active ingredients for environmental fate studies and residue analysis.
• Advanced Material Science: Acts as a precursor for synthesizing deuterated polymers or organic electronic materials to study structure-property relationships.
• Analytical Chemistry: Functions as a high-purity standard for mass spectrometry (MS) and other analytical techniques requiring isotope-labeled references.

Quality Control

Every batch of n-Methylpyrrole-D4 is manufactured and analyzed under strict quality management protocols to ensure exceptional isotopic purity and chemical integrity. Our products undergo rigorous quality testing to ensure compliance with industry standards. Certificates of Analysis (COA) detailing isotopic enrichment (D-atom %), chemical purity, and specific analytical results are available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, well-ventilated place at room temperature (15-25°C). This compound is easily oxidized; for long-term storage, maintaining the material under an inert atmosphere (argon or nitrogen) is recommended to preserve stability and purity.
