Storage method
This product should be sealed and stored in a dry place.
Synthesis method
Meta-hydroxyethyl ketone is benzoylated, brominated, Amination, hydrolysis, catalytic hydrogenation to obtain meta-hydroxyl-α-Methylaminomethylbenzyl alcohol (racemate), reusedd-Tartaric acid is separated to obtain left-handed free base. Suspend the free base in absolute ethanol and add hydrogen chloride–Ethanol solution topH=4, heat to dissolve, add activated carbon to decolorize and filter, add anhydrous ether to the filtrate, and freeze to precipitate crystals. Filter, wash the crystal with a small amount of acetone, and dry to obtain phenylephrine hydrochloride.
Purpose
Adrenergic drugs. It has a constrictive effect on local blood vessels in the body. It is used to extend the time of local anesthesia during surgical procedures and to reduce swelling and inflammation of nasal mucosa congestion.
