Description

Norepinephrine CAS NO 86941-27-7 is a critical catecholamine neurotransmitter and hormone, also known as noradrenaline, essential for the regulation of the sympathetic nervous system. Its primary commercial value lies in its use as a high-purity active pharmaceutical ingredient (API) for life-saving medications. This compound is vital for manufacturers in the pharmaceutical, biotechnology, and advanced research sectors, where consistent quality and reliable supply are paramount.

Application

• Pharmaceutical API: Core ingredient in injectable formulations used as a vasopressor to treat acute hypotension, septic shock, and cardiac arrest.
• Biochemical Research: Essential reagent in neuroscience, pharmacology, and physiology studies investigating adrenergic receptor function, neurotransmission, and stress responses.
• Diagnostic Agent: Used in certain diagnostic tests and procedures to assess autonomic nervous system function.
• Reference Standard: Serves as a certified reference material (CRM) for quality control and analytical method development in pharmaceutical laboratories.
• Veterinary Medicine: Employed in veterinary critical care for similar cardiovascular support applications.
