Description

Dopamine is a critical endogenous catecholamine neurotransmitter and hormone, also known as 3,4-dihydroxyphenethylamine. This compound is essential for neurological signaling and cardiovascular regulation, serving as a direct precursor to norepinephrine and epinephrine. It is a fundamental building block in pharmaceutical synthesis, research, and diagnostic applications, where consistent high purity is paramount for reliable results and product efficacy.

Application

• Pharmaceutical Active Ingredient (API): Used in the formulation of critical drugs for treating conditions such as shock, severe hypotension, and cardiac arrest.
• Biochemical Research & Diagnostics: Serves as a key standard and reagent in neuroscience, endocrinology, and clinical laboratory assays to study neurotransmission and hormonal pathways.
• Reference Standard: Employed in analytical methods development, validation, and quality control (QC) testing within pharmaceutical and biotechnology industries.
• Chemical Synthesis: Acts as a crucial synthetic intermediate for producing more complex catecholamines and related pharmaceutical compounds.
• Cell Culture & In-vitro Studies: Utilized in biomedical research to investigate receptor function, signal transduction, and the effects on various cell types.

Quality Control

Our Dopamine is manufactured under strict quality management systems. Each batch is subjected to comprehensive analytical testing, including HPLC for purity and identity confirmation, to ensure it meets stringent specifications for pharmaceutical and research use. A Certificate of Analysis (COA) detailing all test results is provided with every shipment to guarantee traceability and compliance.

Storage

Preserve in a tightly closed container, protected from light. Store at controlled room temperature (15-25°C) or as specified on the label. Due to its light-sensitive and easily oxidized nature, it is recommended to store under an inert atmosphere for long-term stability. Keep the container in a dry, well-ventilated place.
