Phosphorous Acid (H3PO3), with CAS number 13598-36-2, is a fundamental building block in the chemical industry, and as a dedicated manufacturer, NINGBO INNO PHARMCHEM CO.,LTD. is at the forefront of producing high-quality H3PO3. Understanding its chemical nature and production is key to appreciating its extensive applications.

Chemically, Phosphorous Acid is a diprotic acid, meaning it can donate two protons in aqueous solutions, forming the phosphite and hydrogen phosphite ions. Its most common preparation involves the reaction of phosphorus trichloride (PCl3) with water. This reaction, while effective, requires careful control due to its exothermic nature. Alternatively, it can be produced by the hydrolysis of phosphorus sesquioxide (P4O6). The careful synthesis process ensures the purity and stability of the final product, which is typically a white crystalline solid or an aqueous solution.

As a supplier, NINGBO INNO PHARMCHEM focuses on delivering Phosphorous Acid that adheres to strict quality specifications. This is crucial because impurities can significantly affect its performance in downstream applications such as water treatment, where it is used to produce phosphonates for scale and corrosion inhibition, and in agriculture, as a precursor to effective fungicides. The purity of our H3PO3 directly impacts the efficacy of these end products.

We understand that businesses looking to buy Phosphorous Acid are often concerned with consistency, safety, and competitive pricing. Our manufacturing facilities are equipped with advanced technology, and our quality control processes are robust, ensuring that every batch of Phosphorous Acid meets international standards.
