Levamisole Hydrochloride
1. Basic Product Information
Product Name: Levamisole Hydrochloride
CAS Number: 16595-80-5
Molecular Formula: C11H13ClN2S
Molecular Weight: 240.75
Synonyms: (-)-Tetramisole Hydrochloride, L-Tetramisole HCl, (S)-6-Phenyl-2,3,5,6-tetrahydroimidazo[2,1-b]thiazole hydrochloride
Product Category: Veterinary anthelmintic API, immunostimulant raw material, biochemical laboratory reagent, fine heterocyclic intermediate
2. Physical and Chemical Properties
Physical Indicators
- Appearance: White or off-white crystalline powder
- Odor: Odorless, slightly bitter taste
- Solubility: Freely soluble in water and methanol; soluble in ethanol; slightly soluble in acetone; insoluble in ether, benzene and aliphatic hydrocarbons
- Melting Point: 226–231 °C (decomposes)
- Specific Rotation [α]D2?: -120° ~ -126° (c=10, H?O)
- Density (20 °C): 1.31 g/cm3
- Hygroscopicity: Slightly hygroscopic under high humidity environment
- Aqueous Stability: Stable under neutral and weakly acidic aqueous conditions; slow hydrolysis occurs under high temperature and strong alkaline environment
Chemical Characteristics
- Molecular Structure: Single-enantiomer chiral fused imidazothiazole heterocycle combined with hydrochloride salt
- Core Functional Mechanism: Broad-spectrum nematode paralyzing agent; blocks parasite neuromuscular transmission to eliminate internal worms; also acts as non-specific immune booster for animal bodies
- Photostability: Light-sensitive; long-term UV irradiation triggers discoloration and reduces biological activity
- Thermal Stability: Stable below 200 °C; thermal decomposition above melting point releases irritant sulfur-containing and hydrogen chloride fumes
- Chemical Compatibility: Compatible with weak acidic preparation solvents; incompatible with strong oxidants, concentrated alkalis and heavy metal ions
3. Main Application Fields
- Core Application: Veterinary Antiparasitic Bulk Drug
Main raw material for oral deworming formulations for pigs, cattle, sheep, poultry and aquaculture organisms, effective against roundworms, hookworms and lungworms - Veterinary Immune Enhancer Additive
Added to animal feed to improve livestock and poultry immunity, reduce disease incidence and enhance vaccine efficacy - Biochemical Research Reagent
Alkaline phosphatase inhibitor used in immunohistochemistry, immunoassay and cell staining experiments - Chiral Heterocyclic Synthetic Intermediate
Chiral skeleton substrate for developing novel antiparasitic and immunomodulatory small-molecule compounds
4. Platform Category & Product Group Guidance
1) Domestic B2B Platform Category
Recommended Path: Organic Intermediates / Veterinary Drug Intermediates
Reason: Chiral veterinary anthelmintic hydrochloride intermediate with dual deworming and immune-enhancing functions
2) English Product Group Dropdown Options
Recommended Selection: Basic Organic Chemicals
Do NOT select Pharmaceutical Chemicals exclusively; it is veterinary-use raw material rather than human therapeutic API
3. Standard Foreign Trade Packaging Specification
1kg aluminum foil vacuum bag for lab synthesis and test samples; 25kg double PE-lined light-proof fiber drum for mass production factory orders
