UNSPSC 51131643: Indobufen

This classification denotes a nonsteroidal antiinflammatory drug with the molecular formula C18H17NO3, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier 6T9949G4LZ, chemically known as 4-(1,3-dihydro-1-oxo-2h-isoindol-2-yl)-alpha-ethylbenzeneacetic acid but generally known as indobufen, which bears US NIH Compound Identifier 107641. European Medicines Agency schedules Indobufen in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB08176MIG.

UNSPSC 51131643 Indobufen is a Commodity code for a specific pharmaceutical active ingredient, but the most recent state and local procurement activity tagged under this code does not align with pharmaceutical procurement—instead, it reflects a mislabeling issue in the sourcing system. Sourcewell, a Minnesota local government unit and service cooperative, posted an RFP (Solicitation #061626) in May 2026 to establish a law enforcement equipment contracting framework for participating entities across Washington state (Franklin, Grant, Grays Harbor, Chelan, and Yakima counties) and other jurisdictions nationwide. The scope of the solicitation is law enforcement equipment, not pharmaceutical products, indicating that the UNSPSC code assignment does not match the actual work being procured. This mismatch suggests either a data-entry error in the opportunity record or a system artifact rather than genuine demand for indobufen under state and local procurement.

The geographic scope of the Sourcewell cooperative extends across multiple states and includes thousands of potential user agencies—counties, cities, school districts, higher education institutions, nonprofit organizations, and tribal governments. Proposals were due June 16, 2026 at 3:30 p.m. Central Time through the Sourcewell Procurement Portal. The code shows little relevant recent activity aligned with its pharmaceutical commodity designation; state and local procurement professionals evaluating indobufen supply should verify whether the code is being used accurately in their jurisdictions' internal systems or seek opportunities through health department and hospital procurement channels rather than through law enforcement or cooperative purchasing platforms.
