Description

Clenbuterol-D9 Hcl is a high-purity, deuterium-labeled internal standard essential for precise quantitative analysis in advanced research and regulatory testing. This stable isotope-labeled compound is critical for ensuring accuracy and reliability in mass spectrometry-based methods, eliminating matrix effects and providing definitive results. It is primarily required by analytical laboratories, pharmaceutical R&D teams, and forensic testing facilities engaged in metabolism studies, doping control, and residue analysis.

Application

• Internal Standard for LC-MS/MS: Used as a quantitative reference standard in liquid chromatography-tandem mass spectrometry for the accurate measurement of Clenbuterol and its metabolites.
• Pharmaceutical Research & Metabolism Studies: Enables precise pharmacokinetic and metabolic pathway investigations in drug development.
• Doping Control & Forensic Analysis: A critical component in confirmatory testing protocols for anti-doping agencies and forensic laboratories to detect β-2-agonist misuse.
• Veterinary Drug Residue Testing: Supports food safety programs by ensuring accurate detection of Clenbuterol residues in meat and animal products.
• Method Development & Validation: Serves as a key reagent for developing, optimizing, and validating new analytical methods to meet regulatory guidelines (e.g., FDA, EMA).
• Quality Control in Reference Material Production: Employed in the manufacture and certification of certified reference materials (CRMs) for laboratory proficiency testing.
