Description

Benzoic-3,5-D2 Acid is a deuterium-labeled isotopologue of benzoic acid, specifically deuterated at the 3 and 5 positions of the aromatic ring. This stable isotopic labeling is critical for applications requiring precise molecular tracking and analysis without significant chemical property alteration. It is an essential compound for researchers and manufacturers in the pharmaceutical, agrochemical, and analytical chemistry sectors who require high-purity internal standards or labeled precursors for synthesis.

Application

• Internal Standard for Quantitative Analysis: Used as a stable isotope-labeled internal standard in LC-MS and GC-MS for the accurate quantification of benzoic acid and related compounds in complex matrices.
• Pharmaceutical Research: Serves as a key labeled precursor or metabolite tracer in drug metabolism and pharmacokinetics (DMPK) studies and mechanistic research.
• NMR Spectroscopy: Acts as a useful probe or standard in deuterium NMR spectroscopy due to its specific deuteration pattern.
• Chemical Synthesis: Employed in the synthesis of more complex deuterated molecules where the benzoic acid moiety is required, preserving the isotopic label.
• Food & Environmental Analysis: Utilized in advanced analytical methods to trace and quantify benzoates and their derivatives with high specificity.
