  1. Benzocaine hydrochloride is a local anesthetic drug. Benzocaine hydrochloride is directly applied to the skin and used as a topical pain reliever or in cough drops. Benzocaine works by creating a chemical barrier that halts the build up of sodium, which accumulates as the nerve endings are stimulated by pain. When sodium builds up, electrical signals also build in the nerve ending and are transmitted to the brain, which interprets the signals as pain. Benzocaine hydrochloride is a salt modification of benzocaine, formed when benzocaine is complexed with hydrochloric acid. Compared to benzocaine, benzocaine hydrochloride is more water soluble, making it more appropriate for oral administration.
  2. Benzocaine hydrochloride is usually made into powder or oil paste and used to heal wounds, ulcers, burns, skin abrasion, and hemorrhoids. Through the reduction in the excretion of ammonia and carbon dioxide of fish by benzocaine hydrochloride, the pH and alkalinity values of the transport water remains constant, thereby, benzocaine hydrochloride is used as an aid in the transport of fish.
Chemical Properties:

Benzocaine is also known as ethyl para-aminobenzoate and sinecicine. Those that precipitate from water are colorless or white orthorhombic acicular crystals or crystalline powders, and those that precipitate from ether are square crystals. Odorless. There is a bitter taste. The relative molecular mass is 165.19. The melting point is 92°C. Boiling point is 310°C, 183~184°C (1.87×103Pa). Insoluble in water, soluble in ethanol, ether and chloroform, but also soluble in almond oil, olive oil and dilute acid. Stable in the air.

  1. Benzocaine hydrochloride is the hydrochloride form of the local anesthetic benzocaine. Its pharmacological effects are the same as benzocaine, and its anesthetic effect is weaker than that of procaine. Local absorption is slow, and the effect is long-lasting. Because it is insoluble in water, it cannot be used as an infiltration anesthesia. It has analgesic and antipruritic effects. The medicine is usually made into powder or ointment. Benzocaine hydrochloride is clinically used to treat wounds, ulcers, burns, skin abrasions and hemorrhoids.
  2. Benzocaine hydrochloride (Ethyl 4-aminobenzoate, Ethyl p-aminobenzoate) is a surface anesthetic that works by preventing the propagation of impulses along nerve fibers and nerve endings.
