The synonymous name of 1-ethyl-4-fluorobenzene (Benzene, 1-Ethyl-4-Fluoro-) and the name of the commodity are quite important. In the course of my chemical research, those who know its synonyms may have another name to express its nature and structure. The name of the commodity also varies depending on the use and market.
All substances in Guanfu Chemistry have their names to distinguish. 1-Ethyl-4-fluorobenzene, with its carbon chain and group of groups, gets this scientific name. However, in actual business, either for convenience or because of customary use, its synonymous name can help everyone understand. Such as craftsmen and man-made utensils, the names are different, but they all refer to this thing.
The name of a commodity is related to production and sales. In the words of 1-ethyl-4-fluorobenzene, or used in pharmaceutical synthesis, or as a material auxiliary. For different purposes, the name of business or easy to remember and easy to pass on, in recognition of its use and expansion of its market.

1-Ethyl-4-Fluorobenzene (Benzene, 1-Ethyl-4-Fluorobenzene) is a common chemical compound in chemical research. Safety regulations are of paramount importance during its experimental and production operations.
First, store in a cool, ventilated warehouse. Keep away from fires and heat sources to prevent evaporation or other hazards caused by rising temperature. It should be kept separately from oxidants and food chemicals, and should not be mixed to avoid unexpected chemical reactions. The warehouse needs to be equipped with suitable materials to contain leaks, which is a necessary measure to prevent accidental leaks.
When operating, the operator must undergo special training and strictly abide by the operating procedures. It is recommended to wear a self-priming filter gas mask (half mask) during operation, which can effectively filter harmful gases and protect respiratory safety; wear chemical safety glasses to prevent liquid splashing and injury to the eyes; wear anti-poison penetrating overalls to avoid skin contact; wear rubber oil-resistant gloves to enhance hand protection.
The experimental or production site should have good ventilation facilities to reduce the concentration of this substance in the air. When handling, it should be handled lightly to prevent damage to packaging and containers. If a leak occurs inadvertently, a small amount of leakage can be adsorbed or absorbed by sand or other non-combustible materials; a large amount of leakage needs to be contained by building a dike or digging a pit, covered with foam, to reduce steam disasters, and then transferred to a tanker or a special collector with an explosion-proof pump, recycled or transported to a waste treatment site for disposal.
Furthermore, it is related to personnel emergency treatment. If skin contact, should immediately remove contaminated clothing, rinse with a large amount of flowing water for at least 15 minutes, and then seek medical attention; eye contact, need to lift the eyelids, rinse with flowing water or normal saline, and seek medical attention in a timely manner; if inhalation, quickly leave the scene to fresh air, keep the respiratory tract unobstructed, such as breathing difficulties, oxygen, breathing, cardiac arrest, cardiopulmonary resuscitation and medical treatment immediately.
In short, in the use and operation of 1-ethyl-4-fluorobenzene, safety and operating standards should be strictly observed throughout to ensure the safety of personnel and the smooth progress of experiments and production.
