Description

1,3-Bis(4-Nitrophenyl)-Urea-D8 is a high-purity, deuterium-labeled derivative of a key urea-based compound. This stable isotope-labeled material is critical for ensuring accuracy and reliability in advanced analytical and research applications. It is primarily utilized by researchers and analytical laboratories in the fields of pharmaceutical development, environmental science, and metabolic studies where precise quantification and tracing are required.

Application

• As an internal standard for the precise quantification of its non-labeled counterpart in complex matrices using LC-MS or GC-MS.
• In pharmaceutical research for drug metabolism and pharmacokinetic (DMPK) studies to track the fate of parent compounds.
• For use in environmental analysis as a tracer in studies investigating the degradation or fate of similar nitroaromatic compounds.
• In the development and validation of analytical methods to improve accuracy, precision, and compliance with regulatory guidelines.
• As a key reagent in synthetic chemistry research for preparing other deuterated molecules or studying reaction mechanisms via isotopic labeling.
• Supporting academic research in organic chemistry, biochemistry, and materials science where isotopic purity is essential.

Quality Control

Every batch of 1,3-Bis(4-Nitrophenyl)-Urea-D8 is produced and tested under stringent quality management protocols to ensure exceptional isotopic and chemical purity. Our products undergo rigorous quality testing to ensure compliance with industry standards. Certificates of Analysis (COA) detailing specifications such as isotopic purity (Atom % D), chemical purity (by HPLC), and identity confirmation (by NMR and MS) are available upon request.

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 hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed in a dry environment to prevent degradation. For long-term storage, consider storing under an inert atmosphere.
