Description

1-Amino-2,4-imidazolidinedione-13C3 is a stable isotope-labeled analog of allantoin, where three carbon atoms are replaced with the carbon-13 isotope. This compound is essential for advanced analytical research, providing an internal standard for precise quantification and metabolic pathway tracing using mass spectrometry. It is primarily required by pharmaceutical R&D laboratories, agrochemical scientists, and academic institutions conducting isotope dilution studies in pharmacokinetics, metabolomics, and environmental fate analysis.

Application

• Internal Standard for LC-MS/MS: Used as a quantitative reference standard in liquid chromatography-tandem mass spectrometry for the accurate measurement of allantoin and related metabolites in biological matrices.
• Metabolic Pathway Tracing: Enables the study of purine catabolism and the urea cycle in plant, animal, and human systems through isotope labeling experiments.
• Pharmaceutical Impurity Profiling: Assists in the identification and quantification of process-related impurities and degradants in drug substances and products.
• Agrochemical Research: Applied in environmental fate studies to track the degradation pathways of nitrogen-containing compounds in soil and water.
• Clinical Diagnostics Development: Supports the development of robust assays for biomarkers related to oxidative stress and renal function.
• Nutraceutical Analysis: Used in the quality control and authentication of cosmetic and nutraceutical products containing allantoin.

Quality Control

Our stable isotope-labeled materials are produced and tested under strict quality systems to ensure the highest isotopic and chemical purity for research applications. Each batch is supported by a comprehensive Certificate of Analysis (COA) detailing isotopic enrichment (typically >99 atom % 13C), chemical purity (by HPLC), and identity confirmation (by NMR and MS). We adhere to relevant guidelines for the production of analytical reference standards.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This material is hygroscopic (moisture-sensitive); ensure the container is sealed under an inert atmosphere after each use to maintain stability and prevent moisture uptake.
