Guolan New Materials (Shandong) Co., Ltd. is one of the leading manufacturers and suppliers of phosphorus oxychloride cas 10025-87-3 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 cas 10025-87-3 from our factory.
Product Overview
Phosphorus oxychloride CAS 10025-87-3 (POCl₃) is a highly reactive fine chemical intermediate that appears as a colorless to slightly yellow transparent fuming liquid. It emits dense fumes in moist air and hydrolyzes rapidly upon contact with water or alcohols, yielding phosphoric acid and hydrogen chloride. Serving as a chlorinating agent, dehydrating agent, and phosphorylating reagent, POCl₃ is a workhorse across the agrochemical, pharmaceutical, dye, flame retardant, and phosphate ester manufacturing sectors. Its combination of high reactivity and chemical stability makes it an indispensable building block in fine chemical synthesis.
Guolan New Materials produces industrial-grade phosphorus oxychloride using state-of-the-art continuous synthesis technology. Our product meets POCl₃ content ≥99.50% with PCl₃ impurity ≤0.2%, fully compliant with the HG/T 3606-2009 industry standard. We strike a balance between high purity and cost-effectiveness, catering to high-volume chemical synthesis plants. Our material helps customers stabilize chlorination, dehydration, and phosphorylation processes, reduce production line debugging caused by batch-to-batch raw material variation, and optimize raw material procurement costs without compromising end-product quality.
Guolan New Materials operates a world-class production base in the Dongying Port Economic Development Zone, Shandong Province, with an annual capacity of 100,000 tons. Our rigorous quality control system ensures every batch meets international standards, backed by ISO 9001:2015 certification. We serve customers across Asia, North America, the Middle East, and Southeast Asia, providing 200L HDPE sealed packaging, private label OEM services, and reliable year-round supply. Long-term framework agreements and full-container bulk purchases are welcome.

Key Applications
Agrochemical Intermediate Synthesis
Phosphorus oxychloride is widely used as a chlorinating and dehydrating reagent in the synthesis of organophosphate insecticides, herbicides, and fungicide technical materials. Consistent purity guarantees batch-to-batch uniformity of pesticide intermediates, lowers defect rates, and enables agrochemical plants to maintain stable continuous production lines.
Pharmaceutical Fine Chemicals
In pharmaceutical manufacturing, POCl₃ serves as a chlorination and cyclization reagent for a wide range of pharmaceutical intermediates. Our low-impurity grade effectively reduces byproduct formation and downstream purification costs, making it ideal for fine pharmaceutical production that demands high product purity.
Dyes and Flame Retardants
Used for aromatic ring chlorination and phosphorylation in dye intermediate production, as well as in the synthesis of phosphate ester flame retardants and plasticizers. As a critical chlorinating feedstock, POCl₃ directly impacts downstream product yield and quality stability.
Organic Synthesis and Catalysis
Acting as a condensing agent and cyclization catalyst across diverse organic synthesis reactions, POCl₃ promotes the conversion of a wide range of fine chemicals. Its high reactivity effectively shortens reaction cycles and improves production throughput.
FAQ
Q: What is your MOQ for industrial-grade phosphorus oxychloride?
A: Standard MOQ is one 200L HDPE drum (300 kg net). As a Class 8 corrosive dangerous good, we cannot ship small courier samples. For first-time evaluation, a single drum order supports pilot-scale trials at your plant.
Q: Can you support long-term framework supply agreements?
A: Yes. With 100,000 tons annual capacity, we offer long-term framework agreements with scheduled delivery cycles, volume-based pricing, and priority production scheduling. We work with chemical traders, formulators, and large industrial plants to secure stable year-round supply.
Q: What dangerous goods export documentation do you provide?
A: Every export shipment includes COA, SDS, UN-approved packaging certificate, and dangerous goods declaration. We are fully compliant with IMDG regulations for ocean freight. We ship from Qingdao, Shanghai, and Tianjin ports, supporting both FCL and LCL dangerous goods consolidation.
Q: What is the difference between this industrial grade and the 99.5% high-purity grade?
A: This general industrial grade meets the baseline HG/T 3606-2009 standard (POCl₃ ≥99.50%, PCl₃ ≤0.2%). The 99.5% high-purity grade adds internal control on low-boiling impurities and extended COA, designed for impurity-sensitive pharmaceutical and electronic applications. For general chlorination, dehydration, and phosphorylation in agrochemicals, dyes, and flame retardants, this industrial grade offers the best cost-performance balance.
Q: How should I handle and store POCl₃ safely?
A: POCl₃ is a Class 8 corrosive, fuming liquid. Store in a cool, dry, ventilated dangerous goods warehouse with containers tightly sealed. Keep away from water, moisture, alcohols, and alkalis - hydrolysis releases HCl fumes. Personnel must wear acid-resistant clothing, goggles, gloves, and respiratory protection. Use dedicated pumps and transfer lines made of compatible materials (HDPE, Hastelloy, or glass-lined steel).
Q: What is the shelf life?
A: In original sealed HDPE drums, stored under proper conditions (dry, cool, away from moisture), shelf life is 12 months from manufacture. Once a drum is opened, use it promptly and reseal tightly - moisture ingress hydrolyzes POCl₃ into phosphoric acid and HCl, degrading product quality.
