Description

o-Tolualdehyde-13C1 (Carbonyl-13C) is a stable isotope-labeled derivative of o-tolualdehyde, where the carbonyl carbon atom is enriched with the Carbon-13 isotope. This specific labeling is critical for applications requiring precise molecular tracking and quantification, such as in advanced analytical and metabolic studies. It serves as an essential building block and internal standard for researchers and manufacturers in the pharmaceutical, agrochemical, and analytical chemistry sectors, ensuring data accuracy and reliability.

Application

• As a Carbon-13 labeled internal standard for the accurate quantification of o-tolualdehyde and related compounds in complex matrices using GC-MS or LC-MS.
• A key isotopically labeled precursor in the synthesis of more complex 13C-labeled pharmaceutical intermediates and active ingredients for drug metabolism and pharmacokinetics (DMPK) studies.
• Used in metabolic pathway tracing and mechanistic studies within biochemical and agrochemical research to elucidate reaction pathways.
• Essential for nuclear magnetic resonance (NMR) spectroscopy applications, where the 13C label provides enhanced signal detection for structural analysis.
• Employed in the development and validation of analytical methods to meet rigorous regulatory standards in quality control laboratories.
• Utilized in material science research for investigating reaction mechanisms and catalysis involving aromatic aldehydes.
