Description

(±)-Ractopamine-D3 HCl is a deuterium-labeled internal standard of the β-adrenergic agonist ractopamine, essential for precise quantitative analysis. This high-purity compound is critical for ensuring accuracy and reliability in mass spectrometry-based methods, where it compensates for matrix effects and instrument variability. It is primarily required by analytical laboratories and research institutions in the food safety, veterinary drug residue monitoring, and pharmaceutical development sectors for method validation and regulatory compliance testing.

Application

• Internal Standard for LC-MS/MS analysis of ractopamine residues in meat and animal tissues.
• Quantitative reference material for method development and validation in food safety testing.
• Calibration standard in pharmacokinetic and metabolism studies within veterinary and agricultural research.
• Quality control reagent for the manufacturing and analysis of related pharmaceutical compounds.
• Critical component in high-accuracy analytical workflows for regulatory compliance (e.g., FDA, EU MRLs).
• Use in stable isotope dilution assays to ensure data integrity in complex biological matrices.

Quality Control

Our (±)-Ractopamine-D3 HCl is manufactured under strict quality systems to ensure the high purity and isotopic enrichment required for analytical applications. Each batch is supported by a comprehensive Certificate of Analysis (COA) detailing parameters such as chemical purity, isotopic purity (D-enrichment), and chromatographic profile. We adhere to relevant standards for high-purity reference materials to guarantee consistency and reliability for your critical testing protocols.

Storage

Preserve in a tightly closed container, protected from light. Store at controlled room temperature (15-25°C) in a dry environment. Due to its hygroscopic nature, the material should be handled in a low-humidity atmosphere and desiccated upon opening for long-term stability.
