Guolan New Materials (Shandong) Co., Ltd. is one of the leading manufacturers and suppliers of phosphorus oxychloride for pesticide intermediate in China. With a professional production team, we are able to meet the needs of the majority of our customers. Welcome to wholesale bulk top-quality phosphorus oxychloride for pesticide intermediate from our factory.
Products Description
Phosphorus oxychloride for pesticide intermediate is a specialized formulation optimized specifically for pesticide manufacturing. It delivers POCl₃ content ≥99.50%, PCl₃ ≤0.2%, and boiling-range distillate ≥97.5%. In organophosphate pesticide production, phosphorus oxychloride serves three essential functions - chlorinating agent, dehydrating agent, and phosphorylating reagent - making it a critical raw material in the synthesis routes of organophosphate insecticides, herbicides, and fungicides.
Tailored to the unique requirements of pesticide synthesis, this grade places tight control on PCl₃ impurity levels to prevent phosphorus pentachloride-type side reactions that cause off-spec pesticide intermediates. Rigorous batch consistency ensures stable yields across multi-step pesticide synthesis reactions, reduces production line shutdowns and re-tuning caused by raw material variation, and enables large agrochemical plants to maintain continuous, uninterrupted production.
With an annual capacity of 100,000 tons, Guolan New Materials provides reliable long-term supply to pesticide technical and intermediate manufacturers. We are well-versed in agrochemical industry supplier audit requirements and can deliver complete quality documentation packages and dangerous goods export paperwork to support overseas agrochemical customers through the supplier qualification process. We ship from Qingdao, Shanghai, and Tianjin ports to serve the global agrochemical market.

Key Strengths
- Purpose-Built for Agrochemical Synthesis - Optimized for pesticide manufacturing processes, phosphorus oxychloride delivers triple functionality as a chlorinating, dehydrating, and phosphorylating agent - perfectly matching the synthesis routes of organophosphate insecticides, herbicides, and fungicides.
- Strict PCl₃ Impurity Control - PCl₃ is tightly controlled at ≤0.2% to prevent phosphorus pentachloride-type side reactions that cause off-spec intermediates and product discoloration. This ensures batch consistency and high finished product pass rates in agrochemical production.
- Dependable Bulk Supply - Our 100,000-ton annual capacity supports long-term, continuous raw material supply for large pesticide plants. Long-term supply agreements are available to prevent supply gaps during peak pesticide production season - ideal for bulk procurement.
- Agrochemical-Grade Export Documentation - Complete dangerous goods export document package including COA, SDS, and dangerous goods packaging certificate, meeting the supplier qualification audit requirements of overseas agrochemical enterprises.
- Priority Production Scheduling - Recognizing the seasonal nature of agrochemical demand, we offer priority production scheduling for long-term agrochemical customers, shortening lead times and ensuring timely raw material delivery during peak production periods.
- Private Label OEM Customization - Custom OEM drum label printing is available, with fully customizable branding and product information to meet the unified packaging and labeling standards of large agrochemical enterprises.


Key Applications
Organophosphate Insecticide Synthesis
Phosphorus oxychloride is widely used in organophosphate insecticide technical material synthesis, serving as a key chlorinating and phosphorylating reagent in the production of various insecticide active ingredients. Consistent purity ensures batch uniformity of insecticide intermediates.
Herbicide Intermediate Production
POCl₃ plays a vital chlorination and dehydration role in the synthesis of glyphosate-based and other herbicide active ingredients. Low-impurity specifications ensure stable purity and yield of herbicide intermediates.
Fungicides and Plant Growth Regulators
Used in the intermediate synthesis of fungicides and plant growth regulators, enabling agrochemical companies to expand their product portfolio. Its high reactivity effectively shortens synthesis routes and reduces production costs.
Phosphorus-Containing Agrochemical Additives and Veterinary Drugs
Employed in the synthesis of phosphorus-containing pesticide formulation additives, as well as veterinary anthelmintics and related fine chemical products. Application coverage spans multiple segments of the entire pesticide value chain.
FAQ
Q: Can you provide documentation for agrochemical supplier qualification?
A: Yes. We provide a complete documentation package tailored for agrochemical customers: COA, SDS, dangerous goods packaging certificate, ISO 9001 certificate, and REACH/TSCA compliance declarations as applicable. We support overseas pesticide manufacturers through their supplier audit and qualification processes.
Q: Do you offer priority supply during peak agrochemical season?
A: Recognizing the seasonal demand pattern of agrochemical production, we reserve dedicated production capacity and inventory for long-term agrochemical customers. Priority scheduling ensures raw material delivery on time during peak planting and spray seasons, preventing production line shutdowns due to supply gaps.
Q: Can you supply full container loads for large pesticide plants?
A: Absolutely. With 100,000 tons annual capacity, we routinely ship 20ft and 40ft FCL dangerous goods containers. We support both scheduled quarterly deliveries and urgent top-up orders, with volume-based tiered pricing for long-term bulk agreements.
Q: What role does POCl₃ play in organophosphate pesticide synthesis?
A: POCl₃ serves three critical functions in agrochemical manufacturing: (1) chlorinating agent - converting hydroxyl groups to chloride intermediates; (2) dehydrating agent - promoting cyclization and condensation reactions; (3) phosphorylating reagent - introducing the phosphate ester linkage central to organophosphate insecticides, herbicides, and fungicides.
Q: How does batch-to-batch consistency affect pesticide yield?
A: Pesticide synthesis involves multiple sequential steps where even small raw material impurity fluctuations can cascade into yield loss or off-spec intermediates. Our agrochemical-grade POCl₃ maintains tight PCl₃ and color-body control, ensuring each batch performs identically, reducing re-tuning time and stabilizing finished pesticide technical material quality.
Q: Is this grade suitable for export-grade pesticide manufacturing?
A: Yes. This grade meets HG/T 3606-2009 with additional low-color-body internal control, suitable for manufacturing pesticide technical materials that must meet international FAO and pharmacopoeia specifications. Complete export documentation supports overseas agrochemical registration and supplier audit requirements.
