UNSPSC 51191936 Thiamine disulfide is a Commodity code for pharmaceutical and chemical products used in specialized medical and industrial applications. State and local governments procure under this code for therapeutic pharmaceuticals, parenteral nutrition and intravenous solutions, chemical treatment agents for water and wastewater systems, and specialized medical supplies for correctional healthcare, public health departments, and water utilities. The issuing bodies include state corrections departments, municipal water and wastewater authorities, and county public health and facilities management agencies. Recent solicitations show demand for parenteral products and services—including custom compounded intravenous and total parenteral nutrition solutions with strict delivery timelines—as well as chemical commodities for municipal water treatment operations.

Washington State Department of Corrections issued an RFQQ on September 8, 2026 for parenteral products, services, and equipment across eight correctional facilities, with responses due October 7, 2026; the scope includes TPN, PPN, and IV solutions with 24-hour delivery requirements for PN bags and 8-hour delivery for other parenteral products, with DOC planning to award multiple contractors across three regions through June 30, 2030. The City of Meriden issued an IFB in August 2026 for sodium bisulfite chemical supply to its Water Pollution Control Facility. Broward County, Florida posted an RFI on September 18, 2026 regarding valve parts and repair services for wastewater compliance operations, though this opportunity falls outside the pharmaceutical and chemical commodity focus of the code. Geographic activity centers on Washington State and Connecticut, with additional activity in Florida.
