UNSPSC 51141516: Fosphenytoin

This classification denotes an anticonvulsant agent with the molecular formula C16H13N2O6P.2Na, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier 7VLR55452Z, chemically known as 2,4-imidazolidinedione, 5,5-diphenyl-3-((phosphonooxy)methyl)-, disodium salt but generally known as fosphenytoin sodium, which bears US NIH Compound Identifier 56338. European Medicines Agency schedules Fosphenytoin sodium in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB13919MIG.

Most nations schedule fosphenytoin under HS 29332100 and SITC 51572. As of Q4 2014, FOSPHENYTOIN remains the US FDA Preferred Term for this commodity. Fosphenytoin bears US NLM identifiers UMLS ID C0244656 and NCI Concept Code C65766. SMILES: P(=O)(OCN1C(=O)C(NC1=O)(C1CCCCC1)C1CCCCC1)(O)O.[NA].[NA].

UNSPSC 51141516 Fosphenytoin is a Commodity code that nominally describes a specific anticonvulsant pharmaceutical, yet the most recent state and local procurement activity recorded under this code does not align with that scope. The single opportunity posted under the code—Seminole County, Florida's IFB60459723LAS for Naloxone and Safe Drug Deactivation Systems—reflects procurement of opioid-reversal and drug-disposal products rather than fosphenytoin itself. This mismatch suggests either a data-entry error in the opportunity's UNSPSC classification or a jurisdictional tagging practice that does not cleanly map pharmaceutical commodities to their corresponding codes. The work being solicited comprises annual supply of 1,900 units of naloxone and 800 safe drug deactivation systems, with quarterly deliveries to the Seminole County Community Health Building in Sanford, Florida.

Seminole County's procurement represents the only recent state and local opportunity identified under this code. The IFB, posted June 30, 2026, with a response deadline of July 26, 2023, requires vendors to submit electronic bids through the county's e-Procurement Portal, include all shipping and delivery costs in their proposals, and comply with drug-free workplace certification and E-Verify requirements. The contract term is two years with a one-year renewal option, subject to a three-month probationary period. Potential FEMA funding introduces additional federal compliance obligations under the Clean Air Act and Federal Water Pollution Control Act. Given the single, recent opportunity and the categorical mismatch between the code's nominal scope and actual procurement content, this code shows minimal relevant activity for state and local vendors pursuing fosphenytoin or related anticonvulsant supply contracts.
