This classification denotes a vasodilating agent and antihypertensive agent with the molecular formula C9H15N5O4S, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier 2H6K6Y231J, chemically known as 2-pyrimidinamine, 1,6-dihydro-6-imino-4-(1-piperidinyl)-1-(sulfooxy)-, but more generally known as minoxidil sulfate ester, which bears US NIH Compound Identifier 4202. European Medicines Agency schedules minoxidil sulfate ester or its base in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB08982MIG.

Most nations, for tariff purposes, schedule minoxidil sulfate ester under HS 29335995. SMILES: C1C([N+](C(NC1N2CCCCC2)N)OS(=O)(=O)[O-])N.

UNSPSC 51433606 Minoxidil sulfate ester is a Commodity code nominally designating a pharmaceutical active ingredient, but state and local procurement activity under this code shows minimal relevance to the code's scope. The City of Tampa's recent sealed-bid solicitation (26P00188) for Advanced Life Support Medications supplied to Tampa Fire Rescue in Hillsborough County, Florida, tagged under this code, actually procures emergency-response pharmaceuticals including labetalol, epinephrine, adenosine, and diltiazem — none of which are minoxidil sulfate ester or related compounds. The mismatch suggests either a tagging error in the state and local procurement system or an overly broad code assignment that does not reflect the actual commodity being purchased.

The Tampa Fire Rescue opportunity, posted April 24, 2026 with a response deadline of April 8, 2026, carries an estimated contract value of $40,000 and includes a five-percent Small Local Business Enterprise (SLBE) bid discount not to exceed $10,000, with a one-year initial term and optional two-year renewals plus unilateral extension rights for three additional 30-day periods. The source provides no additional state and local opportunities under this code, limiting visibility into geographic spread or repeat buyer patterns. Firms pursuing this code should verify tagging accuracy with issuing bodies and consider whether opportunities genuinely procuring minoxidil sulfate ester exist outside the visible recent-opportunity pool.
