Description

Ricobendazole-D3 is a deuterated internal standard of the anthelmintic drug ricobendazole, specifically labeled with three deuterium atoms. This compound is essential for ensuring the accuracy and reliability of quantitative mass spectrometry analysis in pharmacokinetic and metabolic studies. It is a critical tool for researchers and quality control laboratories in the pharmaceutical and veterinary medicine sectors who require precise analytical standards for method development and validation.

Application

• Primary use as an internal standard for the quantification of ricobendazole and its metabolites via LC-MS/MS and GC-MS.
• Method development and validation in pharmacokinetic studies for veterinary and human pharmaceutical research.
• Quality control and assurance in the manufacturing of anthelmintic drug products.
• Metabolite profiling and drug metabolism studies to understand absorption, distribution, metabolism, and excretion (ADME).
• Reference material for calibrating analytical instruments in regulatory and compliance testing.
• Use in residue testing for food safety in animal-derived products.

Quality Control

Our Ricobendazole-D3 is manufactured under strict quality management systems. Each batch undergoes rigorous analytical testing, including NMR and mass spectrometry, to confirm isotopic enrichment and chemical purity. A comprehensive Certificate of Analysis (COA) detailing purity, isotopic purity (D-enrichment), and solvent content is provided with every shipment to ensure compliance with your research and regulatory requirements.

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) and should be handled in a dry environment to prevent degradation. For long-term storage, consider desiccants or inert atmosphere.
