Description

Benzaldehyde-13C Semicarbazone is a stable isotope-labeled derivative of benzaldehyde semicarbazone, where the carbonyl carbon is enriched with the carbon-13 isotope. This compound is of critical importance for applications requiring precise molecular tracking and quantification in analytical and research settings. It is primarily needed by researchers and analytical laboratories in the pharmaceutical, agrochemical, and environmental science industries for use as an internal standard in mass spectrometry and NMR spectroscopy.

Application

• Used as an internal standard for the accurate quantification of benzaldehyde or related aldehydes in complex matrices via GC-MS or LC-MS.
• Essential in metabolic pathway studies and stable isotope labeling experiments to trace the fate of carbonyl groups.
• Employed in NMR spectroscopy as a chemical shift reference or for method development due to the distinct 13C signal.
• Applied in pharmaceutical research for the analysis of drug metabolites and degradation products.
• Utilized in environmental analysis to detect and measure aldehyde pollutants.
• Serves as a key intermediate or reference material in the synthesis of other 13C-labeled compounds.
• Supports quality control and method validation in analytical laboratories requiring high-purity isotopic standards.
