Lidocaine
1. Basic Product Information
Product Name: Lidocaine
CAS Number: 137-58-6
Molecular Formula: C14H22N2O
Molecular Weight: 234.34
Synonyms: 2-(Diethylamino)-N-(2,6-dimethylphenyl)acetamide, Lignocaine, Xylocaine base
Product Category: Local anesthetic pharmaceutical API, antiarrhythmic drug raw material, pharmaceutical intermediate
2. Physical and Chemical Properties
Physical Indicators
- Appearance: White or off-white crystalline powder
- Odor: Odorless, slightly bitter taste followed by numbness on tongue contact
- Solubility: Soluble in ethanol, methanol, chloroform and ether; slightly soluble in cold water, soluble in hot water
- Melting Point: 66–69 °C
- Density (20 °C): 1.03 g/cm3
- Hygroscopicity: Non-hygroscopic under sealed dry storage
- Aqueous Stability: Stable under neutral and weakly acidic aqueous environments; slow amide hydrolysis occurs under high temperature and strong alkaline conditions
Chemical Characteristics
- Molecular Structure: Aromatic acetamide derivative with diethylamino alkyl side chain and two methyl substituents on benzene ring
- Core Functional Mechanism: Amide-type local anesthetic; blocks sodium ion channels to inhibit nerve conduction; also used as class IB antiarrhythmic agent for ventricular arrhythmia treatment
- Photostability: Light-sensitive; long-term UV irradiation causes slight yellow discoloration
- Thermal Stability: Stable below 50 °C; prolonged heating above 90 °C accelerates amide bond hydrolysis degradation
- Chemical Compatibility: Compatible with anhydrous polar organic solvents; incompatible with strong oxidants, concentrated strong alkalis and heavy metal ions
3. Main Application Fields
- Core Application: Local Anesthetic API
Raw material for topical, injectable local anesthetic preparations for surgical regional anesthesia, dental anesthesia and pain relief - Cardiovascular Pharmaceutical Raw Material
Active ingredient for emergency antiarrhythmic injections to treat ventricular tachycardia and ventricular fibrillation - Synthetic Intermediate
Parent base raw material for manufacturing lidocaine hydrochloride injection salt - Biochemical Research Reagent
Sodium channel inhibitor standard for neuroscience and cardiac electrophysiology research
4. Platform Category & Product Group Guidance
1) Domestic B2B Platform Category
Recommended Path: Organic Intermediates / Pharmaceutical Intermediates
Reason: Amide-type clinical local anesthetic parent base for prescription drug synthesis
2) English Product Group Dropdown Options
Recommended Selection: Pharmaceutical Chemicals
Do NOT classify as general industrial chemicals; it is controlled human-use anesthetic pharmaceutical raw material
3. Standard Foreign Trade Packaging Specification
1g/5g nitrogen-sealed amber glass vials for reference standards; 1kg aluminum foil vacuum bags for pharmaceutical pilot batches; 25kg double PE-lined light-proof fiber drums for GMP bulk production
