This classification denotes an antitubercular agent with the molecular formula C10H24N2O2.2ClH, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier QE4VW5FO07, chemically known as 2,2-(1,2-ethylenediimino)-di-1-butanol but more generally known as ethambutol hydrochloride, which bears US NIH Compound Identifier 3279. European Medicines Agency schedules Ethambutol hydrochloride in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB11945MIG.

Most nations, for tariff and trade purposes, schedule ethambutol hydrochloride under HS 29221980. As of Q4 2014, ETHAMBUTOL HYDROCHLORIDE remains US FDA's Preferred Term for this commodity. Ethambutol hydrochloride bears US NLM identifiers UMLS ID C0026895 and NCI Concept Code C29033. SMILES: CC[C@@H](CO)NCCN[C@@H](CC)CO.CL.CL.

UNSPSC 51281513 Ethambutol hydrochloride is a Commodity code for a specific anti-tuberculosis pharmaceutical active ingredient, yet the recent state and local opportunities tagged under it show little alignment with the code's nominal scope. The Illinois Department of Public Health's August 2026 piggyback pharmaceutical contract awarded to Chartwell Rx LLC covers Doxycycline Hyclate 100mg tablets and Ciprofloxacin Hydrochloride 500mg tablets—neither ethambutol nor tuberculosis therapies. Seminole County, Florida's June 2026 IFB for 1,900 units of Naloxone and 800 Safe Drug Deactivation Systems annually addresses opioid-overdose response and drug-disposal infrastructure, entirely outside the code's pharmaceutical family. The issuing bodies span a state department (Illinois Department of Public Health) and a county government (Seminole County), but the opportunities themselves show that state and local procurement activity under this code does not track to tuberculosis medications or their supply chain.

The geographic spread evident in recent postings covers Illinois and Florida, though the sparse and misaligned opportunity set suggests this Commodity code sees limited genuine state and local procurement activity for ethambutol hydrochloride specifically. The Illinois contract, awarded on an IFB basis with a $2,999,999.11 total value over 12 months plus two renewal options, reflects a mature cooperative-purchasing vehicle (MMCAP Infuse) that state health departments use for pharmaceutical warehouse buys, but it was piggyback to an existing contract and does not represent active solicitation. The Seminole County opportunity, posted June 30, 2026 with a July 26, 2023 response date (a likely data error in the source), represents a different commodity class entirely. Practitioners evaluating this code should verify whether state and local procurement offices are actually using UNSPSC 51281513 for tuberculosis-drug procurement or whether the tagging reflects administrative backlog or classification drift.
