Description

Benzoic-1-13C Acid is a stable isotope-labeled derivative of benzoic acid, where a carbon-13 atom is incorporated at the carboxyl position. This high-purity labeled compound is essential for applications requiring precise internal standards and metabolic pathway tracing. It is primarily utilized by researchers and manufacturers in the pharmaceutical, analytical chemistry, and life science sectors for quantitative analysis and advanced research.

Application

• Internal Standard for Mass Spectrometry (MS): Serves as a critical quantitative reference standard in GC-MS and LC-MS analyses for accurate measurement of benzoic acid and related compounds.
• Metabolic Pathway Tracing: Used in pharmaceutical research and biochemistry to study drug metabolism, degradation pathways, and biosynthetic routes.
• NMR Spectroscopy: Acts as a chemical shift reference or a probe in nuclear magnetic resonance studies due to the distinct signal of the 13C label.
• Food & Beverage Analysis: Employed in the accurate quantification of benzoic acid, a common preservative, ensuring compliance with food safety regulations.
• Environmental Testing: Used as a labeled standard in the analysis of water and soil samples for benzoate contamination.
• Isotope Dilution Analysis (IDA): A key component in this highly accurate analytical technique for determining the concentration of analytes in complex matrices.
• Chemical Synthesis Intermediate: Used in the synthesis of other 13C-labeled complex molecules for research purposes.
