Phosphorous Acid 99% min (CAS 13598-36-2) is a colourless to white crystalline solid supplied by jinan yuewei chemical co.,ltd in China, with a guaranteed minimum purity of 99%. The compound, also known as phosphonic acid, has the chemical formula H3PO3 and a molecular weight of 81.99. It is offered in standard industrial packaging such as 25 kg bags or 250 kg drums, aligning with global trade practices under HS Code 2809.
This grade is engineered for industrial applications where high consistency is critical. Phosphorous acid is highly soluble in water and alcohol, with a melting point of approximately 73.6°C and a boiling point of 200°C at atmospheric pressure. Typical industry use includes agriculture as a systemic fungicide, chemical manufacturing for phosphonate production, and water treatment. The standard appearance is a white crystalline form, free from visible impurities.
Buyers primarily source this product for agricultural chemical formulation, industrial synthesis, and water treatment systems. The compound is valued for its role as a reducing agent in chemical reactions and its effectiveness in controlling fungal infections in crops. Importers are advised to confirm packaging compatibility with their handling systems, as bulk quantities are common. Trade terms such as FOB or CIF are typically negotiated based on shipment size and destination.

Before ordering Phosphorous Acid 99% min from jinan yuewei chemical co.,ltd, verify the supplier’s ability to provide a Certificate of Analysis (CoA) for the batch, confirming the 99% minimum purity and absence of impurities such as heavy metals. Request documentation for compliance with international standards such as ISO or SGS, as these are not explicitly stated in the supplier’s profile but are critical for quality assurance.
Confirm logistics details, including lead time, which is not specified in the listing. Clarify whether the supplier can accommodate FOB or CIF terms and the preferred port of shipment in China. Packaging compatibility should also be discussed, as the product is available in 25 kg bags or 250 kg drums, and your handling systems must align with these options.
For quality checks, inspect the crystalline form and colour upon receipt to ensure it matches the white, solid appearance described.
