Terbinafine Hydrochloride
1. Basic Product Information
Product Name: Terbinafine Hydrochloride
CAS Number: 78628-80-5
Molecular Formula: C21H26ClN·HCl
Molecular Weight: 327.90
Synonyms: (E)-N-(6,6-Dimethylhept-2-en-4-ynyl)-N-methylnaphthalen-1-methylamine hydrochloride
Product Category: Human antifungal API, allylamine antifungal intermediate, dermatological pharmaceutical raw material
2. Physical and Chemical Properties
Physical Indicators
- Appearance: White to off-white crystalline powder
- Odor: Odorless
- Solubility: Soluble in methanol, ethanol, isopropanol; slightly soluble in water; insoluble in ether, alkanes and benzene
- Melting Point: 204–208 °C (decomposes)
- Specific Rotation: Racemic mixture, no optical rotation
- Density (20 °C): 1.09 g/cm3
- Hygroscopicity: Slightly hygroscopic under high humidity
- Aqueous Stability: Stable under neutral and weakly acidic conditions; hydrolytic degradation occurs under strong alkaline heating
Chemical Characteristics
- Molecular Structure: Allylamine naphthalene derivative combined with hydrochloride salt, containing alkynyl and olefin functional groups
- Core Functional Mechanism: Squalene epoxidase inhibitor; blocks fungal cell membrane synthesis, broad-spectrum fungicidal against dermatophytes, molds and yeasts for skin, nail and hair fungal infections
- Photostability: Light-sensitive; UV exposure causes yellow discoloration and reduced potency
- Thermal Stability: Stable below 180 °C; thermal decomposition releases irritant amine and chlorinated volatile fumes
- Chemical Compatibility: Compatible with polar protic solvents and pharmaceutical excipients; incompatible with strong oxidants, concentrated alkalis and heavy metal salts
3. Main Application Fields
- Core Application: Oral & Topical Antifungal API
Key raw material for antifungal creams, sprays, oral tablets for treating tinea pedis, tinea corporis, onychomycosis and cutaneous candidiasis - Dermatological Formulation Intermediate
Active ingredient for dermatological compound preparations combined with anti-inflammatory additives - Biochemical Research Reagent
Inhibitor for fungal cell membrane metabolism research in microbiology laboratories
4. Platform Category & Product Group Guidance
1) Domestic B2B Platform Category
Recommended Path: Organic Intermediates / Pharmaceutical Intermediates
Reason: Finished human-use antifungal API for dermatological clinical drugs
2) English Product Group Dropdown Options
Recommended Selection: Pharmaceutical Chemicals
