UNSPSC 51201815: Histamine

This classification denotes an immunostimulant with the molecular formula C5H9N3, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier 820484N8I3, chemically known as 4-imidazoleethylamine but generally known as histamine, which bears US NIH Compound Identifier 774. European Medicines Agency schedules Histamine in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB14107MIG. World Health Organization schedules histamine in its Anatomical Therapeutic Chemical (ATC) Classification.

As of Q4 2014, HISTAMINE remains the US FDA Preferred Term for this commodity. Histamine bears US NLM identifiers UMLS ID C0019588 and NCI Concept Code C73238. SMILES: C1=C(NC=N1)CCN.

UNSPSC 51201815 Histamine, a Commodity code, shows minimal recent state and local procurement activity aligned with its nominal scope. The single recent opportunity posted under this code is a sole source notice by the Mississippi State Department of Health for Yellow Fever Vaccine from Sanofi Pasteur, Inc., with objections due August 3, 2026 — a vaccine procurement that does not correspond to histamine as a chemical or pharmaceutical reagent. State health departments and similar public health agencies may solicit under this code for laboratory reagents, diagnostic materials, or pharmaceutical compounds, but the current activity block contains no evidence of broader procurement patterns or repeat buying activity under the Histamine code itself.

The mismatch between the code's nominal scope and the sole opportunity on record suggests either miscoding in the state procurement system or that histamine procurement — if it occurs at all in state and local contracting — does not generate frequent or visible solicitation activity. No geographic concentration, issuing-body mix, or representative opportunity set can be established from a single misaligned notice. A business development professional should verify whether this code reflects actual state and local demand for histamine products or whether relevant opportunities are being tagged under alternative UNSPSC classifications.
