Hydriodic Acid (CAS 10034-85-2) is a strong mineral acid and an aqueous solution of hydrogen iodide that appears as a clear, colorless to slightly yellow liquid, acting as a powerful reducing agent in organic synthesis and supporting the production of organic iodides, pharmaceutical intermediates, and acetic acid via carbonylation. It is formulated to meet high industrial purity standards, ensuring consistent performance in the production of organic iodides and pharmaceutical intermediates.
Widely utilized in the petrochemical sector, this chemical serves as a critical catalyst in the manufacturing of acetic acid via the Cativa and Monsanto processes. Its ability to cleave ethers and reduce functional groups makes it an essential component for synthesizing complex fine chemicals and alkyl iodides.
Our supply chain ensures the delivery of Technical Grade Hydriodic Acid with stable concentration levels suitable for large-scale chemical manufacturing and laboratory applications. We prioritize safety and quality, providing a reliable source for this highly reactive iodine source to support continuous production lines.
