UNSPSC 51282913: Difloxacin

This classification denotes a quinolone antibiotic with the molecular formula C21H19F2N3O3, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier 5Z7OO9FNFD, chemically known as 6-fluoro-1-(4-fluorophenyl)-7-(4-methyl-1-piperazinyl)-4-oxo-1,4-dihydro-3-quinolinecarboxylic acid but generally known as difloxacin, which bears US NIH Compound Identifier 56206. The term DIFLOXACIN is an International Non-Proprietary Name or INN (see WHO INN reference publication, Volume 1, No. 4, 1987, List 27).

UNSPSC 51282913 Difloxacin (Commodity) is tagged infrequently in state and local procurement activity; the recent opportunities block shows pharmaceutical procurements that do not align with difloxacin specifically. The Illinois Department of Public Health awarded a pharmaceutical warehouse piggyback contract through the MMCAP Infuse consortium to Chartwell Rx LLC on August 28, 2026, for Doxycycline Hyclate 100mg tablets and Ciprofloxacin Hydrochloride 500mg tablets — both fluoroquinolone antibiotics but not the difloxacin named in the code. A separate Seminole County, Florida IFB released June 30, 2026, sought Naloxone and Safe Drug Deactivation Systems, which fall outside the antibiotic scope entirely. Neither solicitation reflects actual procurement of difloxacin or suggests state and local agencies are actively buying this specific pharmaceutical compound through open competitive processes at present.

The code shows negligible recent activity aligned to its nominal scope. State and local procurement under difloxacin remains either consolidated through existing blanket contracts not reflected in current open notices, purchased through non-competitive mechanisms, or simply inactive as a discrete line item. Business development professionals should monitor related fluoroquinolone codes and state pharmaceutical cooperative purchasing vehicles (such as MMCAP) for indirect signals of demand, but direct solicitation activity for difloxacin itself is not evident in current state and local postings.
