Description

1,2-Dihydroxybenzene-13C is a stable isotope-labeled analog of catechol, where the carbon atom at the 1-position is replaced by the carbon-13 isotope. This compound is essential for advanced analytical research, providing an internal standard for precise quantification and metabolic pathway tracing using techniques like mass spectrometry and NMR spectroscopy. It is primarily utilized by researchers and manufacturers in the pharmaceutical, agrochemical, and environmental testing industries who require high-fidelity isotopic labeling for method development and regulatory compliance.

Application

• Internal standard for the accurate quantification of catechol and related phenolic compounds in complex biological matrices via LC-MS/MS and GC-MS.
• Tracer compound in metabolic flux analysis and pharmacokinetic studies to elucidate drug and chemical degradation pathways.
• Critical reagent in the synthesis of carbon-13 labeled pharmaceuticals and advanced organic molecules for research.
• Use in environmental fate studies to track the breakdown and transformation of phenolic pollutants.
• Component in the development and validation of analytical reference methods for regulatory submissions.
• Research tool in NMR spectroscopy for structural elucidation and dynamics studies of organic compounds.

Quality Control

Every batch of 1,2-Dihydroxybenzene-13C is produced and analyzed under strict quality management protocols to ensure exceptional isotopic and chemical purity, critical for sensitive analytical applications. Our products undergo rigorous quality testing to ensure compliance with industry standards. Certificates of Analysis (COA) are available upon request and provide comprehensive data including isotopic enrichment (atom % 13C), chemical purity, and impurity profile.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). Due to its properties of being easily oxidized (store under inert atmosphere) and hygroscopic (moisture-sensitive), it is recommended to handle the material under an inert atmosphere such as nitrogen or argon and to allow the vial to equilibrate to room temperature before opening to prevent moisture condensation.
