UNSPSC 51384620: Phenylbutazone

This classification denotes a nonsteroidal antiinflammatory drug with the molecular formula C19H20N2O2, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier GN5P7K3T8S, chemically known as 3,5-pyrazolidinedione, 4-butyl-1,2-diphenyl- but generally known as phenylbutazone, which bears US NIH Compound Identifier 4781. European Medicines Agency schedules Phenylbutazone in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB09787MIG. The term PHENYLBUTAZONE is an International Non-Proprietary Name.

UNSPSC 51384620 Phenylbutazone, a Commodity code, shows minimal alignment with recent state and local procurement activity. The three most recent opportunities tagged to this code—Seminole County's naloxone and drug deactivation systems procurement, Texas HHS's direct-to-manufacturer pharmacy initiative RFI, and MMCAP's multi-source generic pharmaceuticals and OTC products RFP—do not involve phenylbutazone purchasing. Phenylbutazone is a nonsteroidal anti-inflammatory drug primarily used in veterinary medicine (particularly equine practice); the recent solicitations tracked to this code address human-use naloxone, prescription fulfillment infrastructure, and broad generic pharmaceutical supply. The mismatch suggests either a tagging error in the state and local procurement system or dormant purchasing activity under this commodity code.

No recent state and local solicitations for phenylbutazone itself appear in the available records. If state or local government entities are procuring phenylbutazone—typically for animal care or sheltering programs—those opportunities are not currently surfacing in actively posted notices. Business development professionals evaluating this code should verify whether phenylbutazone remains a procurement category for state animal-control agencies, veterinary services, or equine facilities; the recent activity signals suggest this commodity receives little current demand or visibility in the state and local market.
