Abamectin
1. Basic Product Information
Product Name: Abamectin
CAS Number: 71751-41-2
Molecular Formula: C48H72O14 (Avermectin B1a), C47H70O14 (Avermectin B1b)
Molecular Weight: 872.08 (B1a), 858.05 (B1b)
Synonyms: Avermectin B1, Abamectin technical, MK-933
Product Category: Macrolide insecticide & acaricide, agricultural biopesticide raw material, microbial fermentation pesticide
2. Physical and Chemical Properties
Physical Indicators
- Appearance: Pale yellow to dark yellow viscous oily liquid or crystalline solid
- Odor: Faint characteristic microbial fermentation odor
- Solubility: Highly soluble in toluene, chloroform, acetone, methanol and ethyl acetate; slightly soluble in water; insoluble in aliphatic alkanes
- Melting Point: 150–155 °C (technical grade mixture)
- Density (20 °C): 1.16–1.18 g/cm3
- Hygroscopicity: Non-hygroscopic under sealed dry storage
- Aqueous Stability: Stable under neutral and weakly acidic aqueous conditions; rapidly degraded under strong alkaline, high temperature or strong UV irradiation
Chemical Characteristics
- Molecular Structure: Mixture of two macrolide avermectin homologues (B1a ≥80%, B1b ≤20), 16-membered macrocyclic lactone with disaccharide side chain
- Core Functional Mechanism: Glutamate-gated chloride channel agonist; disrupts nerve signal transmission in insects and mites, causing paralysis and death; high selectivity to pests, low toxicity to warm-blooded animals at standard application doses
- Photostability: Extremely light-sensitive; UV light induces rapid photolysis and significant activity loss
- Thermal Stability: Stable below 60 °C; prolonged heating above 90 °C triggers lactone ring hydrolysis and decomposition
- Chemical Compatibility: Compatible with neutral organic solvents and most pesticide emulsifiers; incompatible with alkaline pesticides, strong oxidants and heavy metal ions
3. Main Application Fields
- Core Application: Agricultural Insecticide & Acaricide
Broad-spectrum biopesticide for fruit trees, vegetables, cotton and cash crops; effective against mites, leaf miners, caterpillars, aphids and nematodes - Animal Parasiticide Intermediate
Raw material for livestock and poultry antiparasitic preparations to treat internal and external parasites - Biochemical Research Reagent
Neurotransmitter channel inhibitor standard for invertebrate nerve physiology research - Pesticide Formulation Raw Material
Processed into emulsifiable concentrate, water dispersible granule and suspension concentrate for field crop protection
4. Platform Category & Product Group Guidance
1) Domestic B2B Platform Category
Recommended Path: Organic Intermediates / Pesticide Intermediates
Reason: Fermentation-derived macrolide biopesticide technical material for agricultural pest control
2) English Product Group Dropdown Options
Recommended Selection: Basic Organic Chemicals
Do NOT categorize as pharmaceutical chemicals; it is agricultural pesticide active ingredient
3. Standard Foreign Trade Packaging Specification
100mL amber sealed glass bottle for lab test samples; 200L PE-lined dark plastic drum for bulk technical grade shipments
