Description

Ractopamine-D3 (Mixture Of Diastereomers) is a deuterium-labeled internal standard used for the precise quantification of ractopamine in analytical methods. This stable isotope-labeled compound is critical for ensuring accuracy and reliability in mass spectrometry-based analyses, particularly when compensating for matrix effects and instrument variability. It is an essential reagent for analytical laboratories, regulatory bodies, and food safety programs focused on veterinary drug residue testing and compliance monitoring.

Application

• Internal Standard for LC-MS/MS: Primary use as a quantitative internal standard in liquid chromatography-tandem mass spectrometry (LC-MS/MS) for the analysis of ractopamine residues.
• Food Safety & Veterinary Drug Monitoring: Enables accurate detection and quantification of ractopamine in meat products (e.g., pork, beef), liver, and urine to ensure compliance with international food safety regulations.
• Method Development & Validation: Serves as a key component in the development, validation, and quality control of analytical methods in contract research organizations (CROs) and testing laboratories.
• Pharmacokinetic & Metabolism Studies: Used in research settings to study the absorption, distribution, metabolism, and excretion (ADME) of ractopamine.
• Reference Material for Certified Standards: Acts as a precursor or component in the preparation of certified reference materials (CRMs) for quality assurance programs.
• Regulatory Compliance Testing: Supports testing for export/import controls in regions with strict regulations on ractopamine use in animal husbandry.
