4-Hydroxyphenethylamine, also known as tyramine, is an important natural phenolic amine compound and fine chemical intermediate. It owns phenolic hydroxyl and amino active groups, which can carry out various chemical reactions such as alkylation, acylation and condensation. It is mainly used as core raw material for synthesizing various cardiovascular drugs, central nervous system regulators and biological active agents. It is widely applied in pharmaceutical industry to prepare neurotransmitter related drugs, hypotensive agents and anti-inflammatory medicines. In biochemical research, it acts as an important research substrate for studying amino acid metabolism, biological amine circulation and physiological activity mechanism in organisms. Besides, it can be used in food industry as flavor precursor and detection standard substance, and also applied in cosmetic additives and organic synthetic materials. With stable molecular structure and excellent biological activity, this product plays an irreplaceable role in medical research, biological pharmacy and fine chemical synthesis fields, and has stable supply demand and wide application value in global chemical market.

This substance belongs to biologically active irritant chemical with certain physiological activity and stimulation. Inhalation of its fine powder will cause discomfort and slight irritation to respiratory tract, so operators need to wear dust-proof mask and maintain good ventilation during operation. Direct skin contact may cause local redness, itching and allergic symptoms, staff must wear nitrile protective gloves, and fully clean the contacted skin with soap and running water after work. Once it accidentally enters eyes, it will lead to obvious stinging and conjunctival irritation, please immediately flush eyes with plenty of clean flowing water for more than 15 minutes and take timely medical treatment. Accidental ingestion will affect human nerve and circulatory system, cause dizziness, nausea and physical discomfort, do not induce vomiting casually and seek professional medical help rapidly. It is stable under normal temperature, easy to be oxidized and discolored under strong light and humid environment, and incompatible with strong oxidants and strong acids. It shall be stored tightly sealed away from heat sources. All waste materials must be treated in accordance with local hazardous waste disposal standards to prevent potential harm to human body and ecological environment.
