Description

Oxyclosanid-13C6 is a stable isotope-labeled analog of the veterinary anthelmintic agent oxyclozanide, where six carbon atoms are replaced with the carbon-13 isotope. This compound is an essential internal standard for the precise and accurate quantification of oxyclozanide in complex biological and environmental matrices using advanced analytical techniques like LC-MS/MS. It is primarily required by analytical laboratories, contract research organizations (CROs), and pharmaceutical companies engaged in veterinary drug residue analysis, pharmacokinetic studies, and regulatory compliance testing to ensure data integrity and meet stringent quality standards.

Application

• Internal Standard for Mass Spectrometry: Serves as a critical internal standard for the quantitative analysis of oxyclozanide via Liquid Chromatography-Tandem Mass Spectrometry (LC-MS/MS), correcting for instrument variability and matrix effects.
• Veterinary Drug Residue Testing: Used in regulatory and quality control laboratories to monitor and quantify oxyclozanide residues in meat, milk, and other animal-derived food products to ensure consumer safety.
• Pharmacokinetic and Metabolism Studies: Enables precise tracking of the absorption, distribution, metabolism, and excretion (ADME) of oxyclozanide in research animals during drug development.
• Environmental Fate Analysis: Applied in environmental science to study the degradation, persistence, and transport of oxyclozanide in soil and water systems.
• Method Development and Validation: A key reagent for developing, optimizing, and validating robust analytical methods in compliance with guidelines from agencies like the FDA and EMA.
• Quality Assurance/Quality Control (QA/QC): Supports high-quality manufacturing processes by providing a reliable reference standard for in-house purity assays and impurity profiling.

Quality Control

Our Oxyclosanid-13C6 is manufactured under strict quality-controlled conditions to ensure the highest isotopic purity and chemical integrity. Each batch is fully characterized using NMR (1H, 13C) and High-Resolution Mass Spectrometry (HRMS) to confirm structure and isotopic enrichment. Purity is determined by advanced chromatographic methods (HPLC-UV/DAD). We provide comprehensive Certificates of Analysis (COA) detailing isotopic purity, chemical purity, and all relevant analytical data, supporting traceability and compliance with Good Manufacturing Practice (GMP) principles for reference standards.

Storage

Preserve in a tightly closed container, protected from light. Store at controlled room temperature (15-25°C) or as indicated on the label or COA. This material is hygroscopic (moisture-sensitive) and should be handled in a dry environment to prevent degradation. For long-term storage, consider desiccated conditions.
