Product use
local anesthetic
Benzocaine hydrochloride is the hydrochloride form of the local anesthetic benzocaine. Its pharmacological effects are the same as those of benzocaine, but 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 for infiltration anesthesia. It has analgesic and antipruritic effects. The medicine is usually made into powder or ointment form and is clinically used to treat wounds, ulcers, burns, skin abrasions and hemorrhoids.
Benzocaine is also known as ethyl para-aminobenzoate and sinacin. Those that precipitate from water are colorless or white orthorhombic needle-like crystals or crystalline powder, and those that precipitate from ether are square crystals. Odorless. Has a bitter taste. Chemicalbook relative molecular mass 165.19. Melting point 92℃. Boiling point: 310℃, 183~184℃ (1.87×103Pa). Insoluble in water, soluble in ethanol, ether and chloroform, also soluble in almond oil, olive oil and dilute acid. Stable in air.
