UNSPSC 51453016: Piperazine phosphate anhydrous

This classification denotes an antihelminthic agent with the molecular formula C4H10N2.H3O4P, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier P7S1V82385, chemically known as piperazine, phosphate (1:1), but more generally known as piperazine phosphate anhydrous, which bears US NIH Compound Identifier 64733. European Medicines Agency schedules piperazine phosphate anhydrous or its base in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB03841MIG.

Most nations, for tariff purposes, schedule piperazine phosphate anhydrous under HS 29335990. SMILES: C1CNCCN1.OP(=O)(O)O.

UNSPSC 51453016 Piperazine phosphate anhydrous is a Commodity code, but the recent state and local opportunities tagged under it do not align with its nominal scope. The most recent record—an Illinois Department of Public Health piggyback pharmaceutical warehouse contract awarded to Chartwell Rx LLC in August 2026—covers Doxycycline Hyclate and Ciprofloxacin Hydrochloride tablets, neither of which is piperazine phosphate. A second record from Seminole County, Florida solicits Naloxone and Safe Drug Deactivation Systems, also unrelated to the code's chemical specification. State and local procurement systems occasionally tag pharmaceutical and medical-supply procurements with codes that do not match the actual products being bought, particularly when using piggyback or cooperative purchasing vehicles where tagging may reflect the parent contract classification rather than line-item specifics.

This code shows little relevant recent activity aligned with its stated product. The Illinois contract ($2.999 million over three years with renewal options) and the Seminole County IFB (1,900 units of Naloxone and 800 deactivation systems annually with quarterly deliveries) represent pharmaceutical and medical-supply procurement from a state health department and a county government, respectively, but neither transaction involves piperazine phosphate anhydrous. Buyers evaluating this code should monitor whether future health-department or county public-health solicitations correctly tag chemical-pharmaceutical commodities, or consider whether the code's use in practice has drifted toward broader pharmaceutical-supply categorization in state and local systems.
