Overview
Celangulin V is a naturally occurring insecticidal compound derived from the root bark of Celastrus angulatus, a plant native to China. It belongs to the class of sesquiterpene polyol esters and is widely recognized for its potent bioactivity against a variety of agricultural pests. Unlike synthetic pesticides, Celangulin V is biodegradable and exhibits low toxicity to non-target organisms, making it a preferred choice for organic farming and sustainable agriculture. The compound works by disrupting the nervous system of insects, leading to paralysis and death. Its unique mode of action minimizes the risk of resistance development, which is a common issue with conventional chemical insecticides. Celangulin V is typically formulated as a wettable powder or emulsifiable concentrate for field applications.
Physical and Chemical Properties
Celangulin V is a white to off-white crystalline powder with a molecular weight of 562.65 g/mol. It is sparingly soluble in water but dissolves readily in organic solvents such as ethanol, acetone, and dimethyl sulfoxide (DMSO). The compound has a melting point of approximately 180-185°C and is stable under normal storage conditions. Its chemical structure includes multiple hydroxyl groups and ester linkages, contributing to its bioactivity and selectivity. The compound is sensitive to UV light and alkaline conditions, which can degrade its efficacy over time. Proper formulation and storage are essential to maintain its stability and performance in the field.
Main Applications
Celangulin V is primarily used in agriculture for controlling a wide range of insect pests, including Lepidoptera, Coleoptera, and Hemiptera species. It is particularly effective against leaf-eating caterpillars and beetles, which are common threats to crops like vegetables, fruits, and grains. The compound is often integrated into pest management programs to reduce reliance on synthetic chemicals. In addition to its use in conventional farming, Celangulin V is gaining popularity in organic and sustainable agriculture due to its natural origin and minimal environmental impact. It is also being explored for potential applications in household pest control and veterinary medicine, though these uses are still under development.
Safety and Storage
Celangulin V is considered low-toxicity to mammals, but proper handling procedures should still be followed to minimize exposure. Workers should wear gloves, masks, and protective clothing when handling the compound, especially during formulation and application. Accidental ingestion or inhalation should be avoided, and affected areas should be rinsed thoroughly with water. The compound should be stored in a cool, dry place away from direct sunlight and moisture to prevent degradation. Containers should be tightly sealed and labeled clearly to avoid confusion with other chemicals. In case of spills, absorb the material with an inert substance and dispose of it according to local regulations.
B2B Procurement Guide
When procuring Celangulin V, B2B buyers should prioritize suppliers with a proven track record of quality and reliability. Key factors to consider include the purity of the compound (typically 90-98%), the extraction method used, and compliance with international standards for botanical pesticides. Buyers should also verify the supplier's ability to provide technical support and documentation, such as safety data sheets (SDS) and certificates of analysis (CoA). Pricing can vary significantly based on quantity, purity, and supplier location. Bulk purchases often attract discounts, but buyers should balance cost considerations with quality assurance. It is advisable to request samples for testing before committing to large orders. Additionally, buyers should ensure that the product meets regulatory requirements in their target markets, as pesticide regulations can differ by country.
