Description

Clenbuterol D9 is a deuterated internal standard of the well-known β-2 adrenergic agonist, clenbuterol. This stable isotope-labeled compound is essential for ensuring the accuracy and reliability of quantitative mass spectrometry analysis. It is primarily used by analytical laboratories and research institutions engaged in pharmaceutical development, forensic toxicology, and food safety testing. The compound provides a critical reference point for precise measurement in complex biological matrices.

Application

• Quantitative Mass Spectrometry: Serves as an internal standard for the accurate quantification of clenbuterol and related compounds in LC-MS/MS and GC-MS methods.
• Pharmaceutical Research & Development: Used in pharmacokinetic studies, metabolic profiling, and bioanalytical method development and validation.
• Forensic & Clinical Toxicology: Critical for the definitive identification and precise measurement of clenbuterol in human and animal specimens for doping control and abuse testing.
• Food Safety & Veterinary Drug Residue Analysis: Enables reliable monitoring of clenbuterol residues in meat, livestock feed, and other agricultural products to ensure regulatory compliance.
• Reference Standard Manufacturing: Used as a primary material for the preparation of certified reference standards and calibration solutions.
• Metabolite Studies: Aids in the identification and quantification of clenbuterol metabolites in research focused on drug metabolism and disposition.

Quality Control

Every batch of our Clenbuterol D9 is manufactured and analyzed under strict quality management protocols. We guarantee high chemical purity and isotopic enrichment, which are critical for its performance as an internal standard. Comprehensive testing includes assay by HPLC, determination of isotopic purity by mass spectrometry, and identification by IR and NMR. A detailed Certificate of Analysis (COA) specifying batch-specific results is provided with each shipment.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry place at a controlled room temperature (15-25°C). This product is hygroscopic (moisture-sensitive); ensure the container is sealed tightly after each use to minimize exposure to atmospheric humidity. For long-term storage, consider storing under an inert atmosphere.
