UNSPSC 51101933: Mepacrine

This classification denotes an antiprotozoal agent and antineoplastic with the molecular formula C23H30ClN3O.2ClH.2H2O, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier G6242H2NAA, chemically known as 1,4-pentanediamine, n4- (6-chloro-2-methoxy-9-acridinyl)-n1,n1-diethyl-, dihydrochloride but generally known as mepacrine hydrochloride, which bears US NIH Compound Identifier 237. European Medicines Agency schedules Mepacrine hydrochloride in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB03152MIG.

Most nations schedule mepacrine under HS 29339990 and SITC 51577. SMILES: Clc1cc2nc3c(c(NC(CCCN(CC)CC)C)c2cc1)cc(OC)cc3.

UNSPSC 51101933 Mepacrine (Commodity) shows minimal recent activity in state and local procurement; the code nominally refers to an antimalarial pharmaceutical, but the recent solicitations tagged to this code do not reflect mepacrine procurement. Instead, the opportunities listed involve unrelated pharmaceutical products—doxycycline and ciprofloxacin tablets in one instance, naloxone and drug deactivation systems in another. State and local health departments and county governments occasionally use this code to tag pharmaceutical purchases through cooperative purchasing vehicles and competitive bidding processes, but the mismatch between the code's stated product and what is actually being sourced suggests either misclassification in the source system or a data artifact rather than genuine mepacrine demand.

The one completed award on record—Illinois Department of Public Health's piggyback pharmaceutical warehouse contract with Chartwell Rx LLC for $2,999,999.11 over three years—demonstrates how state agencies leverage consortia like MMCAP Infuse to standardize pharmaceutical sourcing, but it does not reflect procurement of mepacrine itself. Seminole County, Florida issued an IFB in mid-2026 for naloxone and safe drug deactivation systems with quarterly delivery requirements and federal compliance conditions tied to potential FEMA funding, but again, this diverges sharply from the code's nominal scope. Geographic activity appears concentrated in Illinois and Florida based on the recent record, though the code shows limited actionable opportunity for vendors specializing in mepacrine or closely related products. Firms pursuing opportunities under this code should verify with issuing bodies that the code classification matches their product line, as the recent tagged opportunities suggest procurement systems may not be routing mepacrine-related buys through 51101933 consistently.
