• Benzocaine (Benzocaina) is a white needle crystal (CAS No.: 94-09-7, molecular formula: C9H11NO2, molecular weight: 165), melting point of 90-92 ° C, slightly soluble in water, soluble Organic solvent
   
• The local anesthetic intensity of benzocaine is worse than that of Dimethocain e, tetracaine and lidocaine, and slightly stronger than procain e. Therefore, benzocaine does not cause discomfort due to anesthesia when it acts on the mucosa. Benzociane is a fat-soluble drug, so it is also easy to bind to the mucous membrane of the mucous membrane or skin, but it is not easy to penetrate and enter the body to produce toxicity. At the same time, benzocaine is used as a local anesthetic in medicine. It has analgesic and antipruritic effects. It is mainly used for wounds, ulcers, mucosal surfaces and acne anesthesia, pain relief and itching. The ointment can also be used as a nasopharyngeal catheter. Mirror and other lubrication to relieve pain.
   
• The demand for benzocaine in European countries such as Spain, Italy, the United Kingdom and Brazil in South America is high. Most people use benzocaine for medical purposes, and a small number of people use benzociane for experimental research, or mixing with other chemicals, and unconventional uses.
   

• The remarkable feature of benzocaine is that it is easy to bind to the mucous membrane of the mucous membrane or skin surface, and it is not easy to enter the human body to produce toxicity.
   
• Benzocaine is an important organic synthesis intermediate. Mainly used in the production of medicine, plastics and coatings.
   
• Benzocaine has an anesthetic effect, based on which anesthetics such as oxoform, oxocaine and neo-osopron can be synthesized, and since then, many excellent local anesthetics of parabens have been synthesized. Analogs like procaine and many procaine. Such anesthetics have the advantages of good stability, fast onset, long maintenance time and small side effects, and thus are widely used.
   
• The main clinical applications of benzocaine are: temporary relief of pain and itching of the skin, mild burns, sunburn, trauma and bites. The otic preparation is used to alleviate the pain and itching of the acute congestive, concentrated otitis externa, swimming ear inflammation and external use of the ear. It is also effective for toothache, sore throat, mouth ulcers, various hemorrhoids, anal fissures, and genital itching. As a male genital desensitizer, ejaculation is slow. Or an anesthetic lubricant for catheters and endoscopes.
