Uses
Adrenaline (CAS NO.51-43-4) can be used in a variety of preparations for the management of several medical conditions. It is used as a drug to treat cardiac arrest and other cardiac dysrhythmias resulting in diminished or absent cardiac output.And it is the drug of choice for treating anaphylaxis. It is also useful in treating sepsis. It is available in an autoinjector delivery system.It has historically been used for the treatment of croup.
Production
Adrenaline (CAS NO.51-43-4) may be synthesized by the reaction of catechol with chloroacetyl chloride, followed by the reaction with methylamine to give the ketone, which is reduced to the desired hydroxy compound. .jpg)
