Chlorpyrifos Technical FAQ
What is the shelf life of Chlorpyrifos Technical?
When stored properly in original sealed containers below 30°C and protected from moisture, Chlorpyrifos Technical typically has a shelf life of 24 months from the date of manufacture. The product should be kept away from direct sunlight and stored in a well-ventilated area separate from food and feed.
What safety precautions should be taken when handling Chlorpyrifos Technical?
Always wear appropriate personal protective equipment (PPE) including chemical-resistant gloves, protective clothing, goggles, and respiratory protection when handling Chlorpyrifos Technical. Work in well-ventilated areas and avoid contact with skin, eyes, or clothing. In case of exposure, immediately wash affected areas with plenty of water and seek medical attention if necessary.
How does Chlorpyrifos Technical work as an insecticide?
Chlorpyrifos Technical acts as an acetylcholinesterase inhibitor, disrupting the normal function of the nervous system in insects. It works through both contact and stomach action, affecting the insect's ability to control nerve signal transmission, leading to paralysis and eventual death. This mode of action makes it effective against a wide range of insect pests.
Packaging and Storage
Chlorpyrifos Technical is typically available in the following packaging options:
- 25 kg fiber drum with double PE liner
- 50 kg steel drum
- 1000 kg bulk containers (upon request)
For optimal storage conditions:
- Store in a cool, dry, well-ventilated area
- Keep containers tightly closed when not in use
- Protect from physical damage and moisture
- Store away from food, feed, and seed
Regulatory Information
Chlorpyrifos Technical is regulated under various international standards. Users should always consult local regulations before purchase and application. Some key regulatory points include:
- EPA Registration: Subject to regional approvals
- WHO Classification: Class II (Moderately hazardous)
- REACH Status: Registered under EU regulations

More About Chlorpyrifos Technical
What is the recommended disposal method for Chlorpyrifos Technical?
Disposal should be performed in accordance with local, state, and federal regulations. Never dispose of Chlorpyrifos Technical in sewage or drainage systems. Small quantities can be chemically deactivated by professionals. Empty containers should be triple-rinsed and punctured to prevent reuse, then disposed of properly. Consult with licensed waste disposal companies for larger quantities.
Can Chlorpyrifos Technical be used in organic farming?
No, Chlorpyrifos Technical is a synthetic organophosphate compound and is not approved for use in organic farming systems under most organic certification programs worldwide. Organic producers should consult their certification bodies for approved alternatives for pest control.
What is the difference between Chlorpyrifos Technical and formulated products?
Chlorpyrifos Technical refers to the pure active ingredient (typically 95% or higher purity), while formulated products contain the technical material combined with various adjuvants, carriers, and other ingredients to improve application characteristics, stability, or efficacy. Formulated products are ready-to-use, while the technical material requires professional formulation before field application.
