Description

1,3-Cyclohexanedione-13C6 is a stable isotope-labeled analog of 1,3-cyclohexanedione, where all six carbon atoms are the carbon-13 (13C) isotope. This compound is essential as an internal standard in quantitative mass spectrometry, enabling highly accurate and precise measurements by correcting for instrument variability and matrix effects. It is primarily needed by analytical laboratories, pharmaceutical researchers, and agrochemical developers for advanced applications in metabolism studies, pharmacokinetics, and environmental fate analysis.

Application

• Quantitative Mass Spectrometry (MS) Internal Standard: Used as a critical reference compound in LC-MS and GC-MS for the accurate quantification of unlabeled 1,3-cyclohexanedione or related metabolites in complex biological and environmental matrices.
• Pharmaceutical Metabolism and Pharmacokinetic (PK/ADME) Studies: Enables the precise tracking and measurement of drug candidate absorption, distribution, metabolism, and excretion in preclinical and clinical research.
• Stable Isotope Labeling in Chemical Synthesis: Serves as a 13C-labeled building block for the synthesis of more complex isotopically labeled compounds for research and diagnostic purposes.
• Environmental and Agrochemical Analysis: Applied in residue testing and environmental monitoring studies to quantify trace levels of chemicals and their degradation products with high reliability.
• Biochemical Pathway Tracing: Utilized in metabolic flux analysis to investigate biochemical pathways and mechanisms within biological systems.
• Forensic and Doping Control Analysis: Supports high-confidence analytical methods in forensic toxicology and anti-doping programs where definitive quantification is required.
