Description

Pirbuterol-D9 Acetate is a high-purity, deuterium-labeled internal standard critical for advanced analytical quantification. This compound is specifically designed to ensure accuracy and reliability in sensitive mass spectrometry-based analyses by correcting for variations in sample preparation and instrument performance. It is an essential tool for researchers and quality control laboratories in the pharmaceutical and forensic toxicology sectors who require precise measurement of pirbuterol and related compounds.

Application

• Primary use as a deuterated internal standard for the accurate quantification of pirbuterol in biological matrices (e.g., plasma, urine) via LC-MS/MS and GC-MS.
• Critical component in pharmacokinetic and bioequivalence studies for bronchodilator medications.
• Enables reliable detection in doping control and forensic analysis for β-2 agonist substances.
• Supports method development and validation in analytical chemistry laboratories.
• Used in metabolite profiling and drug metabolism research.
• Facilitates high-accuracy testing in pharmaceutical quality control for active pharmaceutical ingredient (API) batches.

Quality Control

Every batch of Pirbuterol-D9 Acetate is manufactured under controlled conditions and undergoes rigorous analytical testing to ensure exceptional isotopic purity and chemical identity. Our quality assurance protocols are designed to meet the stringent requirements of analytical reference standard applications. A comprehensive Certificate of Analysis (COA), detailing isotopic enrichment, chemical purity, and spectroscopic confirmation, is provided with each shipment and is available upon request.

Storage

Preserve in a tightly closed container, protected from light. Store at controlled room temperature (15-25°C) or as indicated on the label. Due to its hygroscopic (moisture-sensitive) nature, the container must be kept in a dry environment. For long-term storage, consider desiccants or inert atmosphere to maintain stability and purity.
