Description

4-Methoxy-D3-Benzoic Acid CAS NO 27914-54-1 is a stable isotope-labeled derivative of 4-methoxybenzoic acid, where three hydrogen atoms are replaced by deuterium. This high-purity compound is essential for applications requiring precise analytical standards and metabolic pathway tracing. It is primarily utilized by researchers and manufacturers in the pharmaceutical, agrochemical, and analytical chemistry industries for use as an internal standard in mass spectrometry and NMR spectroscopy.

Application

• Internal standard for quantitative analysis via LC-MS (Liquid Chromatography-Mass Spectrometry) and GC-MS.
• Deuterated tracer in pharmacokinetic and drug metabolism studies.
• Key intermediate for synthesizing deuterium-labeled complex molecules in pharmaceutical research.
• NMR spectroscopy standard for method development and validation.
• Building block in the development of labeled agrochemicals and their metabolites.
• Use in stable isotope probing to study biochemical pathways.
