Procaine hydrochloride Chemical Properties,Uses,Production

Local anesthetic

Procaine hydrochloride is a topical anesthetic, which can block the nerve fiber conduction temporarilyand has a narcotic effect,strong effect, low toxicity, and non-addictive, but on the skin, mucosal penetration is weak, unsuitable for surface anesthesia, patients are used for infiltration, conduction and spinal anesthesia.
White fine needle crystal or crystalline powder at room temperature, no smell, taste slightly bitter and Ma, soluble in water, soluble in ethanol, slightly soluble in chloroform, almost insoluble in ether. Procaine hydrochloride ester bond structure can be hydrolyzed to produce amino acid and diethylaminoethanol, under certain conditions, the amino acid may be further decarboxylated toxic aniline.
The structure of procaine hydrochloride with aromatic primary amino, easy oxidation discoloration pH, temperature, UV, oxygen and metal ions can accelerate the oxidation discoloration. The aqueous solution was stable in pH3.0~5. So preparation of procaine hydrochloride injection, it generally takes add acid to regulate pH 3.3 to 5.5, and strictly control the sterilization temperature and time. to 100 ℃ steam sterilization 30min circulation is appropriate, and should pay attention to shading, sealed save.
The product structure of aromatic primary amino group in dilute hydrochloric acid can generate diazonium salt with sodium nitrite, coupling reaction occurs when add alkaline β-naphthol, generating azo compounds scarlet.
The above information is edited by the chemicalbook of Kui Xiongfeng.

Chemical Properties

Small, colorless crystals or white, crys- talline powder; odorless; stable in air. Soluble in water and in alcohol at 25C; slightly soluble in chloroform; almost insoluble in ether; solutions acid to litmus.


Local anesthesic;Na+ channel blocker


Procaine is a local anesthetic of the amino ester group that is primarily used as a topical anesthetic. Procaine is also used to control the pain of intramuscular injection of penicillin as well as in dentistry.


Non Caine local anesthetic.


A sodium channel blocker and DNA methylation inhibitor

brand name

Novocain (Hospira).


Toxic by ingestion.

Contact allergens

Procaine is a local anesthetic with para-amino function. Sensitization mainly concerns the medical, dental, and veterinary professions.

Safety Profile

Poison by ingestion, subcutaneous, intravenous, and intraperitoneal routes. Human systemic effects: acute renal fdure. May have human reproductive effects. See also ESTERS. When heated to decomposition it emits very toxic fumes of HCl and NO,. Used as a local anesthetic.

Purification Methods

Novocain is recrystallised from aqueous EtOH. It is soluble at 25o in H2O (86.3%), EtOH (2.6%) and Me2CO (1%), it is slightly soluble in CHCl3, but is almost insoluble in Et2O. The anhydrous free base is recrystallised from ligroin or Et2O and has m 61o.
