Phosphorus Oxychloride (POCl3) Supplier in Malaysia
- Also known as
- POCl3
- Phosphoryl Chloride
- phosphorus(V) Oxychloride
- Phosphorus Oxytrichloride
Phosphorus oxychloride supplier in Malaysia for phosphate ester, agrochemical, fine chemical and wafer diffusion buyers. Written POCl3 by most process engineers and named phosphoryl chloride on formal documents (CAS 10025-87-3), it is a colourless to pale yellow fuming liquid with a sharply pungent odour. It moves only as a sealed liquid, because it reacts with the moisture in ordinary air.
Grade is the leading question on this product rather than an afterthought. Technical material feeds triaryl and trialkyl phosphate ester manufacture, organophosphate agrochemical intermediates and general chlorination duty. High purity electronic grade sits well above that, holding trace metals and water at the levels a diffusion furnace will accept from a dopant source.
This is a reactive phosphorus chloride, not a phosphate salt and not phosphoric acid. It is also a separate product from phosphorus trichloride and phosphorus pentachloride, which is the confusion that reaches enquiry desks most often. Naming the compound and the grade together removes the ambiguity before anything is quoted.
State the grade, the assay and impurity limits your process works to, the quantity and the delivery point when you enquire. Availability, pack format and documentation are settled with the quotation. Supply is subject to applicable requirements.

Phosphorus Oxychloride grades and forms
We supply several forms to suit different formulating and dosing setups. If you need a size that is not listed, ask us.
| Grade | Form | Assay | Typical use | Packing |
|---|---|---|---|---|
| Technical grade phosphorus oxychloride | colourless to pale yellow liquid | — | Triaryl and trialkyl phosphate ester manufacture for plasticiser and flame retardant systems, and organophosphate agrochemical intermediate production charged at bulk industrial scale. | Sealed drum or tank supply; the pack format is settled in the quotation. |
| Synthesis and fine chemical grade | clear fuming liquid | purity, colour and residue limits set against the required grade | Chlorinating and dehydrating reagent duty in pharmaceutical, dye and speciality synthesis, where a low colour and low residue parcel is written into the reaction specification. | Sealed drum supply; pack format is confirmed against the enquiry. |
| High-purity electronic grade | high-purity liquid | metal and moisture limits held to the buyer's diffusion specification | Phosphorus dopant source for semiconductor and photovoltaic wafer diffusion, where trace metals and water content decide whether the material can enter the furnace at all. | Sealed drum or dedicated high-purity pack, confirmed with the quotation. |

Phosphorus Oxychloride applications
Safety and handling
Keep in tightly closed containers in a cool, dry and well-ventilated place, and exclude moisture at every transfer. It reacts with water and with damp air, releasing acidic fumes, so keep it clear of water, alcohols, bases and other incompatible materials. Use suitable protective equipment and work to the safety information issued for the grade quoted.
Common questions about phosphorus oxychloride
Is phosphorus oxychloride the same as phosphoryl chloride?
Yes, the same material. Phosphoryl chloride is the formal name, phosphorus(V) oxychloride and phosphorus oxytrichloride appear on older datasheets, and POCl3 is what most process engineers write. Any of those terms in an enquiry is read as the same compound.
What is the difference between phosphorus oxychloride and phosphorus trichloride?
They are different products. Phosphorus trichloride carries no oxygen on the phosphorus atom and behaves differently in reaction, and phosphorus pentachloride is a solid chloride again distinct from both. Order the compound you need by name, since substituting one for another changes the chemistry and the handling.
Is this an inorganic phosphate or a form of phosphoric acid?
No. It is a reactive phosphorus chloride that hydrolyses to acidic products rather than a phosphate salt or an acid solution ready for dosing. Buyers who need a phosphate salt or an acid grade should specify that material instead, because the two serve entirely different processes.
Should I request technical or electronic grade POCl3?
Technical grade covers phosphate ester, flame retardant and agrochemical intermediate work. Electronic grade is a much tighter product used as a dopant source in wafer diffusion, with metal and moisture limits far below general industrial expectations. State the duty and your specification limits, since the gap between the two is commercially large.
Why does moisture control matter so much with this product?
The liquid hydrolyses on contact with water or humid air and releases acidic fumes, which is why it is kept in sealed containers and transferred with dry lines. Any specification for water content should be stated in the enquiry so the correct pack and handling arrangement is quoted.
What details are needed for a phosphorus oxychloride price enquiry?
Send the grade, the assay and impurity limits, the quantity per shipment and per year if it is a repeat requirement, and the delivery location. Mention the documentation you need and the intended reaction, so the quotation addresses the complete requirement rather than a bare unit price.
