Benzocaine Hydrochloride Powder Pain Killer Drug CAS 23239-88-5 GMP
The potential of benzocaine-hydrochloride as an aid in the
transport of fish was investigated. When used at a concentration of
25 mg/l the anaesthetic caused a reduction in the excretion of
ammonia and carbon dioxide by the fish, while, as a result of the
reduced activities of the fish, the pH and alkalinity values of the
transport water remained fairly constant. When
benzocaine-hydrochloride was not used, the activities of the fish
produced a significant deterioration in water quality evidenced by
the accumulation of ammonia and carbon dioxide.
Benzocaine hydrochloride salt is the hydrochloride salt form of the
local anesthetic benzocaine, the pharmacological effects with
benzocaine, procaine weaker than the effect of anesthesia.
Partially absorbed slowly, lasting effect. Because they do not
dissolve in water, can not be used for anesthesia, pain relief,
anti-itch effect, drugs are usually made of powdered or oil paste,
used to treat wounds Clinically, ulcers, burns, skin abrasions and
Benzocaine is also called amino benzoate, Xinaixixin.

1. Benzocaine is an anaesthetic drug, mostly used for application
direct to the skin. Benzocaine HCl is a salt modification of
benzocaine, formed when benzocaine is complexed with hydrochloric
acid. Often, drug salts have enhanced properties compared with the
parent compound. For example, benzocaine hydrochloride is more
water soluble than benzocaine, making it more appropriate for oral
2. There are quite a few different uses for Benzocaine, these
(1) As an ingredient in cough syrups
(2) To treat cold sores
(3) To treat toothache
(4) To treat irritation from dentures
(5) To treat earache
(6) As a surgical local anesthetic
(7) In condoms used to delay ejaculation
(8) To tranquilize Fish
3. Benzocaine is the main local anesthesia for pain experienced in
the gums, teeth and also for relieving sore throat. Apart from
treating oral irritations it is also used to treat otic pain i.e.
pain experienced in the ear. Moreover it is incorporated in certain
surgical procedures as a local anesthesia. It comes prepared in a
variety of ways such as gel, aerosol and paste for otic purposes.
Benzocaine spray used to relieve pain in the throat and lining of
the mouth is not applicable to children under the age of two unless
prescribed by a doctor. The spray is used on patients fitting
dentures on their gums to relieve pain. It is important to note
that in such cases the spray should not be a long term solution to
pain caused by poorly fitted dentures.
Benzocaine VS Benzocaine HCL:
Benzocaine Base CAS: 94-09-7 and Benzocaine HCL CAS: 23239-88-5.
they are at two opposite ends of the ph scale. HCL is obviously a
heavy acid. Benzocaine a base. The HCL is used in cocaine cutting
on large scales because the HCL mixed with the cocaine make it
water soluble but the Base is actually used in the production of
crack cocaine because basically crack is just cocaine with out the
Hydrochloride. So they would want a base in it. Other than that
both are technically used as "room deodorizers" thats how they are
marketed but everyone know what its sold for.
