Tetracaine
1. Basic Product Information
Product Name: Tetracaine
CAS Number: 94-24-6
Molecular Formula: C15H24N2O2
Molecular Weight: 264.36
Synonyms: 4-(Butylamino)benzoic acid 2-(dimethylamino)ethyl ester, Amethocaine
Product Category: Local anesthetic pharmaceutical API, ester-type anesthetic intermediate, clinical pharmaceutical raw material
2. Physical and Chemical Properties
Physical Indicators
- Appearance: White to off-white crystalline powder
- Odor: Odorless, slightly bitter taste
- Solubility: Soluble in ethanol, methanol, chloroform and ether; slightly soluble in hot water; barely soluble in cold water
- Melting Point: 41–46 °C
- Density (20 °C): 1.04 g/cm3
- Hygroscopicity: Slightly hygroscopic under high humidity environment
- Aqueous Stability: Stable under neutral and weakly acidic conditions; susceptible to ester hydrolysis under heated alkaline aqueous solution to generate p-butylaminobenzoic acid byproducts
Chemical Characteristics
- Molecular Structure: Para-aminobenzoic acid ester derivative with butylamino substituent and dimethylaminoethyl ester side chain
- Core Functional Mechanism: Long-acting ester local anesthetic; blocks sodium ion channels of nerve cell membrane to inhibit nerve signal transmission, widely used for surface anesthesia of mucous membranes
- Photostability: Light-sensitive; long-term UV irradiation triggers discoloration and reduces anesthetic activity
- Thermal Stability: Stable below 40 °C; prolonged heating above 60 °C accelerates ester 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: Human Local Anesthetic API
Active raw material for ophthalmic, otolaryngologic and mucosal surface anesthetic formulations; applied for eye drops, nasal sprays and topical anesthesia preparations - Pharmaceutical Synthetic Intermediate
Precursor for manufacturing tetracaine hydrochloride injection raw material via salt-forming reaction - Biochemical Research Reagent
Nerve channel inhibitor standard for neuroscience and anesthesia mechanism laboratory research
4. Platform Category & Product Group Guidance
1) Domestic B2B Platform Category
Recommended Path: Organic Intermediates / Pharmaceutical Intermediates
Reason: Ester-type local anesthetic parent base for clinical mucosal anesthetic drug synthesis
2) English Product Group Dropdown Options
Recommended Selection: Pharmaceutical Chemicals
Do NOT classify as general industrial chemicals; it is controlled clinical anesthetic 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 lightproof fiber drums for GMP bulk production
