Description

4-Methylbenzophenone-D3 is a deuterium-labeled analog of 4-methylbenzophenone, a key compound in analytical chemistry and research. This stable isotope-labeled standard is essential for ensuring accuracy and reliability in quantitative mass spectrometry, where it serves as an internal reference to correct for variations in sample preparation and instrument response. It is primarily needed by analytical laboratories, pharmaceutical researchers, and environmental testing facilities engaged in method development, pharmacokinetic studies, and trace contaminant analysis.

Application

• Internal Standard for LC-MS/MS: Used as a quantitative reference standard in liquid chromatography-tandem mass spectrometry for the analysis of benzophenone derivatives.
• Pharmaceutical Research: Employed in drug metabolism and pharmacokinetics (DMPK) studies to track the fate of parent compounds.
• Environmental Analysis: Facilitates the precise measurement of 4-methylbenzophenone and related compounds in environmental samples like water and soil.
• Food Safety Testing: Applied in methods to detect and quantify potential photoinitiator migrants from packaging materials into foodstuffs.
• Method Development & Validation: Critical for developing robust, accurate, and reproducible analytical methods in compliance with regulatory guidelines.
• Isotope Dilution Mass Spectrometry (IDMS): Serves as the labeled spike in IDMS, the gold-standard technique for achieving high metrological accuracy.
