This classification denotes an immunostimulant with the molecular formula C59H108N6O19P.NA.H2O, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier 1LM890Q4FY. European Medicines Agency schedules mifamurtide in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB25179. The term MIFAMURTIDE is an International Non-Proprietary Name or INN (see WHO INN reference publication, Volume 21, no. 1, 2007, list 57). Most nations schedule mifamurtide under HS 29329990 and SITC 51569.

As of Q4 2014, MIFAMURTIDE remains the US FDA Preferred Term for this commodity. Mifamurtide bears US NLM identifiers UMLS ID C0129341 and NCI Concept Code C1394. SMILES: P(=O)(OCC(OC(=O)CCCCCCCCCCCCCCC)COC(=O)CCCCCCCCCCCCCCC)(OCCNC(=O)C(NC(=O)CCC(NC(=O)C(NC(=O)C(OC1C(NC(=O)C)C(OC(C1O)CO)O)C)C)C(=O)N)C)O.[NA].O.

UNSPSC 51201812 Mifamurtide is a Commodity code nominally identifying a specific immunological agent used in cancer therapeutics, but recent state and local procurement activity under this code does not align with that scope. The Mississippi State Department of Health posted a sole source notice in July 2026 for Yellow Fever Vaccine from Sanofi Pasteur, Inc., a product outside the mifamurtide classification entirely. The mismatch suggests either a data-entry error in the state procurement system or systematic miscoding of vaccine solicitations in this UNSPSC family. No additional relevant recent opportunities appear under this code.

The lone activity on record — Mississippi State Department of Health's notice of proposed sole source procurement, posted July 13, 2026, with an objection deadline of August 3, 2026 — does not represent actionable procurement under the mifamurtide commodity code. Firms pursuing opportunities under this code should note the absence of substantive recent activity and the apparent mislabeling of the single posted notice. If state procurement offices are using this code to tag vaccine acquisitions broadly, the actual scope of work being solicited may differ materially from the code's stated commodity definition.
