UNSPSC 51281657: Neomycin c

This classification denotes an aminoglycoside antibiotic with the molecular formula C23H46N6O13, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier 6B1U1NS16Z, chemically known as d-streptamine, o-2,6-diamino-2,6-dideoxy-.alpha.-d-glucopyranosyl-(1->3)-o-.beta.-d-ribofuranosyl-(1->5)-o-(2,6-diamino-2,6-dideoxy-.alpha.-d-glucopyranosyl-(1->4))-2-deoxy-, but more generally known as neomycin c, which bears US NIH Compound Identifier 4454.

UNSPSC 51281657 Neomycin c is a Commodity code for a single antibiotic pharmaceutical product, but the recent state and local opportunities associated with this code do not align with neomycin procurement. Instead, the opportunities show solicitations for other pharmaceutical products—naloxone, doxycycline, and ciprofloxacin—suggesting either a tagging mismatch in the underlying data or a broader pharmaceutical-supply classification issue. State and local buyers using this code appear to source pharmaceuticals through piggyback cooperative purchasing arrangements and traditional competitive bidding, typically via county health departments and state health agencies. Vendors supplying under these structures must meet standard compliance requirements including drug-free workplace certification, E-Verify authorization, insurance coverage, and in some cases federal compliance obligations when FEMA funding is involved.

Recent activity shows two examples: the Illinois Department of Public Health awarded a $2.99 million three-year piggyback contract through the MMCAP Infuse consortium to Chartwell Rx LLC (Bid 26-482DPH-PREPD-B-53392, IFB, awarded August 28, 2026) for doxycycline and ciprofloxacin tablets, and Seminole County, Florida issued an IFB (60459723LAS, posted June 30, 2026, due July 26, 2026) for 1,900 units of naloxone and 800 safe drug deactivation systems annually with quarterly deliveries. Neither opportunity explicitly addresses neomycin. Procurement activity under this code appears concentrated in Florida and Illinois, with delivery and inventory management requirements reflecting public health and community emergency-response missions. Because the tagged opportunities diverge from the code's stated scope, buyers evaluating this code should verify its actual use in their target jurisdictions before pursuing strategy.
