Description

Norepinephrine L-Bitartrate Hydrate, 99% is a high-purity salt form of the essential neurotransmitter and hormone norepinephrine (noradrenaline). This compound is critical for research and development in the pharmaceutical and life sciences sectors, where precise chemical composition and stability are paramount. It is primarily utilized by researchers and manufacturers in neuropharmacology, cardiovascular studies, and the production of reference standards and diagnostic reagents.

Application

• Pharmaceutical Reference Standard: Used as a primary standard for the quality control and assay validation of pharmaceutical formulations containing norepinephrine.
• Biochemical Research: Essential for in vitro and in vivo studies investigating adrenergic receptor function, neurotransmission, and the sympathetic nervous system.
• Diagnostic Reagent Manufacturing: A key raw material in the production of diagnostic kits and assays for measuring catecholamine levels in clinical samples.
• Cardiovascular & Neuropharmacology R&D: Employed in research models to study blood pressure regulation, cardiac function, and central nervous system disorders.
• Cell Culture & Signal Transduction Studies: Used to stimulate adrenergic pathways in cellular models to study downstream biochemical effects.
