Description

Zilpaterol-D7 is a deuterium-labeled analog of the β-adrenergic agonist zilpaterol, specifically designed for use as an internal standard in analytical chemistry. This high-purity stable isotope-labeled compound is essential for ensuring the accuracy and reliability of quantitative mass spectrometry analyses. It is primarily utilized by analytical laboratories, research institutions, and quality control departments within the pharmaceutical, veterinary medicine, and food safety sectors for method development, validation, and regulatory compliance testing.

Application

• Internal Standard for LC-MS/MS: Critical for the precise quantification of zilpaterol residues in complex biological matrices, such as animal tissues, urine, and feed.
• Veterinary Drug Residue Analysis: Enables accurate monitoring and confirmation of zilpaterol levels to ensure compliance with maximum residue limits (MRLs) in food-producing animals.
• Pharmacokinetic and Metabolic Studies: Used in research to track the absorption, distribution, metabolism, and excretion (ADME) of zilpaterol in vivo.
• Method Development and Validation: Serves as a key reference material for developing robust and sensitive analytical methods in accordance with guidelines from agencies like the FDA and EMA.
• Quality Assurance/Quality Control (QA/QC): Employed in laboratory proficiency testing and as a system suitability check to guarantee the consistency of analytical results.
• Forensic and Doping Control Analysis: Supports the detection and confirmation of the unauthorized use of zilpaterol in sports and livestock production.
