Description

L-Noradrenaline Bitartrate is a high-purity salt form of the endogenous catecholamine neurotransmitter and hormone, L-Norepinephrine. This compound is critical for pharmaceutical research and development, serving as a key reference standard and active pharmaceutical ingredient (API) intermediate. It is essential for manufacturers and research institutions in the pharmaceutical, biotechnology, and life science sectors, particularly for cardiovascular and neurological research, as well as in the production of critical care medications.

Application

• Pharmaceutical API Synthesis: A crucial intermediate in the manufacturing of injectable formulations of norepinephrine, a life-saving vasopressor used to treat acute hypotension and shock.
• Biochemical Research: Used as a reference standard in studies of adrenergic receptors, neurotransmitter release, and sympathetic nervous system function.
• Analytical Standard: Serves as a primary standard for HPLC, LC-MS, and other analytical methods to quantify norepinephrine levels in pharmaceutical products and biological samples.
• Diagnostic Reagent Manufacturing: Employed in the production of diagnostic kits and assays for measuring catecholamine levels in clinical laboratories.
• Neuroscience & Pharmacology: A fundamental tool for in vitro and in vivo research exploring autonomic regulation, stress response, and cardiovascular physiology.

Quality Control

Our L-Noradrenaline Bitartrate is manufactured under strict quality management systems. Each batch undergoes comprehensive analytical testing to ensure identity, purity, and consistency, meeting the stringent requirements for pharmaceutical intermediates and reference standards. A Certificate of Analysis (COA) detailing specifications such as assay (HPLC), chiral purity, and related substances is provided with every shipment. We support compliance with cGMP, ICH Q7 guidelines, and relevant pharmacopoeial standards (e.g., USP, EP) for applicable grades.

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 product is hygroscopic (moisture-sensitive); the container must be kept tightly sealed in a dry environment to prevent degradation. For long-term storage, consider desiccated conditions.
