Description

Urea (13C, 15N2) is a stable isotope-labeled analog of urea, where the carbon atom is the 13C isotope and both nitrogen atoms are the 15N isotope. This compound is essential for advanced analytical research, providing a non-radioactive tracer for metabolic and pharmacokinetic studies. It is primarily used by researchers and manufacturers in the pharmaceutical, agrochemical, and life science industries for applications requiring precise isotopic labeling.

Application

• Metabolic Pathway Tracing: Used as a stable isotope tracer in mass spectrometry (MS) and nuclear magnetic resonance (NMR) studies to investigate urea cycle disorders and nitrogen metabolism.
• Internal Standard for Quantitation: Serves as a critical internal standard in liquid chromatography-mass spectrometry (LC-MS) and gas chromatography-mass spectrometry (GC-MS) for the accurate quantification of urea in complex biological matrices.
• Pharmaceutical Research & Development: Employed in drug metabolism and pharmacokinetics (DMPK) studies to track the fate of nitrogen-containing drug molecules.
• Agricultural Science: Used in research to study nitrogen uptake, utilization, and fertilizer efficiency in plants.
• Clinical Diagnostics: Applied in the development of advanced diagnostic assays for conditions related to renal function and protein catabolism.
• Environmental Science: Utilized as a tracer in studies of nitrogen cycling in soil and aquatic ecosystems.

Quality Control

Our Urea (13C, 15N2) is manufactured under strict quality control protocols to ensure high isotopic and chemical purity. Each batch is supported by a comprehensive Certificate of Analysis (COA) detailing isotopic enrichment (typically ≥99 atom % 13C and ≥99 atom % 15N), chemical purity, and specific analytical data from techniques such as NMR and MS. We adhere to relevant industry standards for stable isotope-labeled compounds.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at room temperature (15-25°C). This material is hygroscopic (moisture-sensitive) and must be kept in a desiccated environment to maintain stability and purity.
