Description

Fenoterol-D6 Hydrobromide is a deuterium-labeled internal standard of the β-2 adrenergic receptor agonist, Fenoterol. This high-purity, isotopically labeled compound is essential for achieving precise and reliable quantitative analysis in complex biological matrices. It is primarily used by analytical laboratories and pharmaceutical R&D departments engaged in pharmacokinetic studies, drug metabolism research, and bioanalytical method development. The use of this stable isotope-labeled analog ensures accurate measurement by compensating for variations during sample preparation and mass spectrometric analysis.

Application

• Internal Standard for LC-MS/MS and GC-MS quantification of Fenoterol in biological samples (plasma, serum, urine).
• Metabolite identification and profiling studies in pharmacokinetics (PK) and absorption, distribution, metabolism, and excretion (ADME) research.
• Method development and validation for regulatory bioanalysis supporting drug development and clinical trials.
• Quality control and assurance in pharmaceutical manufacturing for batch consistency of Fenoterol-based medications.
• Forensic and anti-doping analysis for the accurate detection of Fenoterol.
• Environmental analysis research for tracing pharmaceutical residues.

Quality Control

Our Fenoterol-D6 Hydrobromide is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including NMR and mass spectrometry for structural confirmation and isotopic purity, and HPLC for chemical purity assessment. We provide a detailed Certificate of Analysis (COA) with each shipment, which includes batch-specific data on purity, isotopic enrichment, and residual solvents, ensuring traceability and compliance with your research or quality standards.

Storage

Preserve in a tightly closed container, protected from light. Store at controlled room temperature (15-25°C) or as indicated on the label. This product is hygroscopic (moisture-sensitive). Keep the container tightly sealed in a dry environment to prevent degradation. For long-term storage, consider storing desiccated.
