UNSPSC 51191573: Amiloride hydrochloride anhydrous

This classification denotes the anhydrous form of a potassium-sparing diuretic and intercalating agent with the molecular formula C6H8ClN7O.ClH.2H2O, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier FZJ37245UC, chemically known as pyrazinecarboxamide, n-amidino-3,5-diamino-6-chloro-, monohydrochloride but more generally known as amiloride hydrochloride, which bears US NIH Compound Identifier 16230.

European Medicines Agency schedules Amiloride hydrochloride in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB00445MIG. Most nations, for tariff and trade purposes, schedule amiloride hydrochloride anhydrous under HS 29339990. As of Q4 2014, AMILORIDE HYDROCHLORIDE ANHYDROUS remains US FDA's Preferred Term for this commodity. SMILES: C1(C(NC(C(N1)CL)N)N)C(=O)NC(=N)N.CL.

UNSPSC 51191573 Amiloride hydrochloride anhydrous is a Commodity code, but the recent state and local opportunities posted under this code show minimal alignment with pharmaceutical-grade amiloride products. Instead, the three most recent solicitations cover water treatment chemicals (sodium bisulfite for municipal wastewater control), specialized valve systems and parts for wastewater facilities (DeZurik/APCO equipment with SCADA integration), and parenteral nutrition and intravenous solutions for correctional healthcare — none of which fall within the scope of a diuretic pharmaceutical compound. The code's nominal scope does not reflect the actual procurement activity being tagged to it by state and local issuing bodies.

The geographic spread of activity includes Washington state (Department of Corrections), Florida (Broward County), and Connecticut (City of Meriden), with the recent opportunities spanning water and wastewater infrastructure, correctional health services, and municipal chemical supply. The Washington State Department of Corrections RFQ for parenteral products, services, and equipment (RFQQK13020, due October 7, 2026) solicits intravenous solutions and parenteral nutrition bags for eight facilities across three regions and encourages small business, minority-owned business, women-owned business, and veteran-owned business participation under Chapter 39.19 RCW. The Broward County, Florida Request for Information on DeZurik/APCO valves and repair services (BLD6232026F23, due September 29, 2026) seeks to determine alternative suppliers for wastewater treatment equipment currently sole-sourced to Controls Specialties, Inc. The City of Meriden, Connecticut IFB for sodium bisulfite (B027-15, due July 29, 2026) addresses chemical supply for the Water Pollution Control Facility. Given the mismatch between the code's pharmaceutical definition and the unrelated commodities and services being solicited, this code shows little decision-relevant recent activity for pharmaceutical suppliers.
