Basic Information
Product Name: Prilocaine
CAS Number: 721-50-6
Alias: Propitocaine, 2-(Propylamino)-o-propionotoluidide
Molecular Formula: C13H20N2O
Molecular Weight: 220.31
IUPAC Name: N-(2-methylphenyl)-2-(propylamino)propanamide
Structural Information
- Structure Type: Amide-type amino local anesthetic
- Structural Features: Toluene parent structure connected with propanamide and propylamino groups; weak vasodilatory effect, low cardiac toxicity, metabolized via liver amidase, less methemoglobinemia risk at clinical routine dosage
Physical & Chemical Properties
- Appearance: White crystalline powder
- Odor: Odorless
- Melting Point: 37–38 °C
- Boiling Point: Distills under reduced pressure, decomposes at high temperature
- Solubility: Slightly soluble in water; soluble in ethanol, methanol, chloroform, acetone, dilute acid; insoluble in alkane solvents
- Stability: Stable under dry sealed storage; stable in weak acid/neutral medium; easy hydrolysis under strong alkaline heating; light stable, non-hygroscopic
Synthesis & Applications
Production Method
2-Methylaniline reacts with 2-bromopropionic acid to form amide intermediate, then alkylation with propylamine, refined by recrystallization.
Main Applications
- Pharmaceutical API: Local anesthetic for infiltration anesthesia, nerve block, epidural anesthesia; often compounded with lidocaine
- Medical preparation raw material: Raw material for topical anesthetic cream, injection formulations
- Anesthesiology research reagent: Comparative test compound for local anesthetic pharmacology
