UNSPSC 51191523: Urea osmotic diuretic

This classification denotes an osmotic diuretic with the molecular formula CH4N2O, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier 8W8T17847W, chemically known as urea, homopolymer but generally known as carbamide, which bears US NIH Compound Identifier 1176. Carbamide most often comes in base, perhydrate, peroxide, phenylacetate, and resin forms. European Medicines Agency schedules Urea in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB15662MIG.

World Health Organization schedules carbamide in its Anatomical Therapeutic Chemical (ATC) Classification. SMILES: O=C(N)N.

UNSPSC 51191523 Urea osmotic diuretic is a Commodity code nominally covering specific pharmaceutical products, but recent state and local procurement activity under this code shows minimal direct alignment with the code's abstract scope. The two most recent opportunities tagged to this code involve sodium bisulfite chemical supply for municipal water treatment and generic multi-source pharmaceuticals through a cooperative purchasing vehicle — neither of which centers on urea osmotic diuretics as a primary procurement focus. The mismatch suggests either inconsistent code assignment by issuing bodies or that state and local governments are tagging broader pharmaceutical and chemical categories to this code without precision matching to the commodity name.

Activity under this code spans state cooperative purchasing (Minnesota Multistate Cooperative Purchasing Alliance administering on behalf of participating state and local facilities across Minnesota and Oregon) and municipal procurement (City of Meriden, Connecticut for water treatment operations). The most recent opportunities closed or are closing in the first half of 2026: Minnesota Department of Administration issued an RFP for generic pharmaceuticals and OTC products with a March 26, 2026 response date through MMCAP, and the City of Meriden posted an IFB for sodium bisulfite chemical supply with a July 29, 2026 due date. No standout repeat buyers emerge from the limited recent record. Geographic activity concentrates in the upper Midwest and Northeast, with Minnesota and Connecticut representing the documented jurisdictions. Given the sparse activity and the lack of direct alignment between the code's nominal scope and the work actually being solicited, this code does not show material procurement volume or consistent demand for the specific commodity it nominally describes.
