Dopamine is one of the most important catecholamines, playing a key role in the central nervous system and renal system. Imbalances in dopamine secretion in the body can lead to diseases such as heart disease, schizophrenia and Parkinson's disease. 3,4-Dihydroxyphenyl-Ethylamine Hydrochloride is the hydrochloride form of dopamine and has better stability. 3,4-Dihydroxyphenyl-Ethylamine Hydrochloride has good water solubility, can enhance myocardial contractility, increase blood output, and is widely used in shock syndrome caused by myocardial infarction, trauma, endotoxin sepsis, cardiac surgery, renal failure, congestive heart failure, etc.


① α and β receptor agonist, dilating peripheral blood vessels

② Antishock effect


①Treat Parkinson's disease

3,4-Dihydroxyphenyl-Ethylamine Hydrochloride is used to treat Parkinson's disease and can significantly reduce and control the symptoms of movement disorders in patients. By supplementing dopamine, it can improve nerve conduction function and reduce symptoms such as muscle stiffness and tremor.

②Treat depression

3,4-Dihydroxyphenyl-Ethylamine Hydrochloride is also used to treat depression and can improve a patient's mood and emotional stability. In addition, 3,4-Dihydroxyphenyl-Ethylamine Hydrochloride also has certain effects on other neurological diseases, such as anxiety disorders and attention deficit hyperactivity disorder.

③Treat clinical hypotension

3,4-Dihydroxyphenyl-Ethylamine Hydrochloride is a dopamine receptor agonist that can excite the heart and increase renal blood flow. It is used for hemorrhagic, cardiac asthenia and septic shock. 3,4-Dihydroxyphenyl-Ethylamine Hydrochloride can also be used in the treatment of circulatory system diseases such as heart failure and shock, as well as in clinical applications such as supporting blood pressure maintenance.


① Low blood pressure regulator

② Antishock agent

③ Raw material for the synthesis of norepinephrine

Raw materials in the pharmaceutical field: 3,4-Dihydroxyphenyl-Ethylamine Hydrochloride is commonly used in clinical practice. It is suitable for shock syndrome caused by myocardial infarction, trauma, endotoxin sepsis, cardiac surgery, renal failure, congestive heart failure, etc. And shock cannot be corrected after replenishing blood volume, especially those with oliguria and normal or relatively low peripheral vascular resistance.


3,4-Dihydroxyphenyl-Ethylamine Hydrochloride is mainly prepared through chemical synthesis methods, involving some production steps such as catalytic hydrogenation, which has a high risk factor and large environmental pollution. Viablife Biotech selects self-developed biosynthesis technology, uses renewable carbon sources to synthesize 3,4-Dihydroxyphenyl-Ethylamine Hydrochloride through biological fermentation through strict strain selection and advanced automated processing technology, and provides customers with high-quality and stable 3,4-Dihydroxyphenyl-Ethylamine Hydrochloride products.

Advantages of Viablife’s 3,4-Dihydroxyphenyl-Ethylamine Hydrochloride:

①Pure appearance and color: Viablife’s 3,4-Dihydroxyphenyl-Ethylamine Hydrochloride is a pure, snow-white powder with uniform particle size.

②Higher purity: Viablife’s 3,4-Dihydroxyphenyl-Ethylamine Hydrochloride synthesis process is a biosynthetic process, with higher purity and fewer impurities.

③Uniform particle size: Viablife’s 3,4-Dihydroxyphenyl-Ethylamine Hydrochloride adopts a uniform particle size to strictly control the particle size, making the 3,4-Dihydroxyphenyl-Ethylamine Hydrochloride particle size more uniform, with better fluidity and rapid dissolution.
