Description

4,4'-Dimethoxybenzophenone-D8 is a deuterated analog of 4,4'-dimethoxybenzophenone, where eight hydrogen atoms are replaced with deuterium. This isotopic labeling is critical for applications requiring high chemical stability and minimal signal interference, serving as an essential internal standard in quantitative mass spectrometry. It is primarily utilized by researchers and quality control laboratories in the pharmaceutical, agrochemical, and analytical chemistry sectors for method development and precise analysis.

Application

• Internal Standard for LC-MS/MS and GC-MS analysis in pharmacokinetic and metabolomic studies.
• Deuterated reference material for quantitative NMR (qNMR) spectroscopy.
• Tracer compound in environmental fate studies and degradation pathway analysis.
• Stable isotope-labeled starting material or intermediate in synthetic organic chemistry.
• Calibration standard for analytical method validation in regulatory compliance (FDA, ICH).
• Component in the development and testing of deuterated pharmaceuticals and agrochemicals.

Quality Control

Our 4,4'-Dimethoxybenzophenone-D8 is produced under strict quality management systems. Each batch undergoes rigorous analytical testing, including HPLC, NMR, and MS, to ensure high isotopic purity and chemical identity. Certificates of Analysis (COA) detailing isotopic enrichment (typically >98 atom % D), chemical purity, and trace solvent content are provided with every shipment to support your research and compliance needs.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Keep the container sealed to prevent moisture absorption and contamination.
