UNSPSC 51283963: Phthalylsulfamethizole

This classification denotes a sulfonamide anti-infective agent with the molecular formula C17H14N4O5S2, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier TAY5ZBM0MO, chemically known as 4-((5-methyl-1,3,4-thiadiazol-2-yl)sulfamoyl)phthalanilic acid but more generally known as phthalylsulfamethizole, which bears US NIH Compound Identifier 3047837. European Medicines Agency schedules Phthalylsulfamethizole in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB09798MIG.

The term PHTHALYLSULFAMETHIZOLE is an International Non-Proprietary Name. PHTHALYLSULFAMETHIZOLE is scheduled in the U.S. International Trade Commission's Harmonized Tariff System (HTS) Pharmaceutical Appendix. SMILES: S(=O)(=O)(NC1SC(NN1)C)C1CCC(NC(=O)C2C(CCCC2)C(=O)O)CC1.

UNSPSC 51283963 Phthalylsulfamethizole is a Commodity code for a specialized pharmaceutical compound, but the recent state and local contract activity recorded under this code does not align with the code's nominal scope. The two most recent opportunities tagged under this code involve procurement of Naloxone and safe drug deactivation systems (Seminole County, Florida) and a completed award for Doxycycline Hyclate and Ciprofloxacin Hydrochloride tablets (Illinois Department of Public Health), neither of which are phthalylsulfamethizole or closely related sulfonamide compounds. The tagging mismatch suggests either miscoding in the state and local procurement databases or use of this code as a catch-all for certain pharmaceutical purchases. State and local healthcare and public health agencies, including county health departments and state departments of public health, appear to be the primary issuing bodies under this code based on recent activity.

Geographic activity is limited to Florida and Illinois based on the two most recent opportunities. Seminole County, Florida issued an IFB on June 30, 2026 for annual procurement of 1,900 units of Naloxone and 800 Safe Drug Deactivation Systems with quarterly deliveries to the Seminole County Community Health Building, with a response deadline of July 26, 2026. The Illinois Department of Public Health completed an Invitation for Bid (bid number 26-482DPH-PREPD-B-53392) on August 28, 2026, awarding a $2,999,999.11 pharmaceutical warehouse piggyback contract to Chartwell Rx LLC through the MMCAP Infuse cooperative purchasing consortium for a 12-month initial term with two renewal options. This code shows sparse recent activity, and the work actually being solicited does not consistently match the phthalylsulfamethizole product name.
