Description

Prenalterol Sulfate Ester CAS NO 81924-67-6 is a key pharmaceutical intermediate and reference standard of significant interest in medicinal chemistry. Its primary value lies in its role as a precursor or derivative in the synthesis and analytical profiling of β-adrenergic receptor agonists. This compound is essential for research and development laboratories, pharmaceutical manufacturers, and quality control units focused on cardiovascular and respiratory therapeutics.

Application

• Pharmaceutical Intermediate: Critical precursor in the synthesis of β-adrenergic agonists and related active pharmaceutical ingredients (APIs).
• Analytical Reference Standard: Used for method development, validation, and quality control (QC) testing in HPLC, LC-MS, and other chromatographic systems.
• Metabolite Studies: Employed in pharmacokinetic and drug metabolism research to study the biotransformation pathways of prenalterol and similar compounds.
• Process Chemistry & Impurity Profiling: Serves as a known impurity or degradation product standard to ensure the purity and stability of final drug substances.
• Biochemical Research: Utilized in vitro studies to investigate the structure-activity relationships (SAR) of β-agonist drugs.

Quality Control

Our Prenalterol Sulfate Ester is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing, including identification, purity assay, and impurity profiling, to ensure it meets stringent specifications for pharmaceutical research and development. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and compliance with your quality requirements.

Storage

Preserve in a tightly closed container, protected from light. Store in a cool, dry, and well-ventilated area at controlled room temperature (15-25°C). Due to its hygroscopic (moisture-sensitive) nature, the container must be kept tightly sealed after opening to prevent degradation from atmospheric moisture.
