UNSPSC 51191558: Mefruside

This classification denotes a diuretic with the molecular formula C13H19ClN2O5S2, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier X1NS9SNS92, chemically known as 1,3-benzenedisulfonamide, 4-chloro-n(sup 1)-methyl-n(sup 1)-((tetrahydro-2-methyl-2-furanyl)methyl)- but generally known as mefruside, which bears US NIH Compound Identifier 4047. European Medicines Agency schedules Mefruside in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB08710MIG.

UNSPSC 51191558 Mefruside is a Commodity code covering chemical products used in municipal water treatment and pharmaceutical supply chains, though recent state and local solicitations under this code show disparate applications that do not align cleanly with the nominal mefruside designation. The City of Meriden, Connecticut, solicited sodium bisulfite for its Water Pollution Control Facility under IFB B027-15 (due July 29, 2026), specifying chemical supply for water treatment operations with unit-cost pricing evaluation and standard municipal contractor insurance requirements including $1,000,000 to $2,000,000 General Liability coverage and performance and payment bonds. A second major opportunity—the Minnesota Multistate Cooperative Purchasing Alliance (MMCAP) RFP S1070000015802, administered by the Minnesota Department of Administration's Office of State Procurement—sought generic multi-source pharmaceuticals and OTC products for distribution across participating state and local government facilities in Minnesota and Oregon, with proposals due March 26, 2026 and contract effectiveness on July 1, 2026. MMCAP required vendors to supply through three authorized wholesalers (AmerisourceBergen/Cencora, Cardinal Health, and Morris & Dickson), maintain cGMP and DSCSA certification, submit detailed NDC and SKU data, and accept a 3 percent administrative fee, with pricing weighted at 75 percent of evaluation scoring and performance penalties of $200 to $1,500 per violation.

The code shows limited geographic concentration, with recent activity in Connecticut (municipal water treatment) and Minnesota/Oregon (pharmaceutical cooperative purchasing). Issuing bodies span municipal utility departments (City of Meriden) and state-administered multistate cooperative purchasing vehicles (MMCAP), reflecting the fragmented buyer base typical of water-treatment chemical procurement and pharmaceutical supply aggregation. The pharmaceutical opportunity represents the larger-scale activity, structured as a two-year contract with optional extensions through June 30, 2028 and multi-award capability, while the water-treatment chemical solicitation reflects routine municipal consumables procurement. Vendor participation in either stream requires different operational capabilities—wholesaler relationships and supply-chain visibility for pharmaceuticals, and logistics and insurance compliance for municipal chemical supply—making this code's breadth atypical for a single commodity designation.
