Description

Noradrenalinebitartrate CAS NO 51-04-1 is the bitartrate salt form of the endogenous catecholamine neurotransmitter and hormone, norepinephrine. This high-purity pharmaceutical intermediate is critical for ensuring the efficacy and safety of final drug formulations. It is primarily required by manufacturers in the pharmaceutical and biotechnology sectors for the production of critical care medications, diagnostic agents, and advanced research applications.

Application

• Pharmaceutical Active Ingredient (API): Core component in the synthesis of injectable formulations for acute hypotension and cardiac arrest.
• Diagnostic Reagent: Used in biochemical assays and diagnostic kits to measure catecholamine levels or related enzymatic activity.
• Biochemical Research: Essential standard and reagent in neuroscience, pharmacology, and endocrinology research studying adrenergic receptors and sympathetic nervous system function.
• Veterinary Medicine: Employed in veterinary pharmaceutical preparations for emergency care in animals.
• Reference Standard: Serves as a high-purity calibrant in quality control laboratories for HPLC, LC-MS, and other analytical methods.

Quality Control

Our Noradrenalinebitartrate is manufactured under strict quality management systems. Each batch is tested to meet stringent specifications for identity, purity, and potency, aligning with pharmaceutical-grade expectations. A comprehensive Certificate of Analysis (COA) detailing results for assay, related substances, residual solvents, and microbiological attributes is provided with every shipment to ensure full traceability and regulatory compliance.

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 material is light-sensitive (store away from light) and easily oxidized (store under inert atmosphere). For long-term storage, consider maintaining the product under an inert atmosphere such as nitrogen or argon to prevent degradation.
