Description

Dl-Allantoin-5-13C; 1-15N CAS NO 285978-19-0 is a high-purity, isotopically labeled derivative of allantoin, a key compound in biochemical research and pharmaceutical development. This stable isotope-labeled standard is essential for ensuring the accuracy and reliability of quantitative mass spectrometry (MS) and nuclear magnetic resonance (NMR) analyses. It is primarily required by research scientists and quality control laboratories in the pharmaceutical, biotechnology, and agrochemical industries for use as an internal standard in pharmacokinetic studies, metabolic pathway tracing, and impurity profiling.

Application

• As a stable isotope-labeled internal standard for the precise quantification of allantoin in biological matrices (e.g., plasma, urine) via LC-MS/MS or GC-MS.
• For metabolic pathway and tracer studies in mammalian systems, plant biology, and microbiology to elucidate biochemical mechanisms.
• In pharmaceutical research and development for drug metabolism and pharmacokinetics (DMPK) studies of compounds metabolized through the allantoin pathway.
• Use in quality control and method validation for the accurate analysis of allantoin in cosmetic, dermatological, and nutraceutical products.
• As a critical reagent in isotope dilution analysis to achieve high accuracy and compensate for matrix effects and analyte loss during sample preparation.
• For environmental and agricultural research investigating nitrogen metabolism and purine degradation in plants and soil.

Quality Control

Our isotope-labeled materials are produced under strict quality systems to ensure the highest isotopic and chemical purity. Each batch is characterized by advanced analytical techniques including NMR, MS, and HPLC to confirm isotopic enrichment, chemical identity, and purity. Certificates of Analysis (COA) are provided, detailing isotopic purity (atom % 13C and 15N), chemical purity, and relevant analytical data. We support compliance with GLP and GMP standards for research and regulatory submissions.

Storage

Preserve in a tightly closed container, protected from light. Store at controlled room temperature (15-25°C) in a dry environment. This compound is hygroscopic (moisture-sensitive); keep the container tightly sealed in a desiccated area to prevent absorption of atmospheric moisture.
