UNSPSC 51161569: Montelukast sodium

This classification denotes an anti-asthmatic agent with the molecular formula C35H35ClNO3S.Na, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier U1O3J18SFL, chemically known as cyclopropaneacetic acid, 1-((((1r)-1-(3-((1e)-2-(7-chloro-2-quinolinyl)ethenyl)phenyl)-3-(2-(1-hydroxy-1-methylethyl)phenyl)propyl)thio)methyl)-, monosodium salt but more generally known as montelukast sodium, which bears US NIH Compound Identifier 5281041.

UNSPSC 51161569 Montelukast sodium is a Commodity code nominally addressing a specific asthma and allergy medication, but recent state and local procurement activity under this code shows a significant mismatch: the posted opportunities involve water treatment chemicals (sodium hypochlorite and sulfuric acid) and multi-source generic pharmaceuticals and OTC products sourced through authorized wholesalers, neither of which directly addresses montelukast sodium supply. The scope of work actually being solicited spans chemical bulk commodities for municipal water systems and broad-based pharmaceutical contracting through cooperative purchasing vehicles that aggregate demand across state and local health and social service facilities. Issuing bodies include county public works departments managing utility operations and state cooperative purchasing alliances coordinating procurement across multiple jurisdictions and member entities.

Geographic activity centers on California, where the County of Orange OC Public Works posted an Invitation for Bid (IFB 0803008401RE) due March 27, 2026, for sodium hypochlorite and sulfuric acid delivery to water treatment facilities with five-year contract terms and set-asides for certified Orange County Local Small Businesses and Disabled Veteran Business Enterprises. The Minnesota Multistate Cooperative Purchasing Alliance (MMCAP), administered by the Minnesota Department of Administration's Office of State Procurement, posted a Request for Proposal (S1070000015802) due March 26, 2026, for generic multi-source pharmaceuticals and OTC products distributed to participating state and local government facilities across Minnesota and Oregon, with awards effective July 1, 2026, and contract terms of two years for new vendors. The code shows limited direct relevance to montelukast sodium procurement; pursue opportunities only if your firm supplies water treatment chemicals or participates in multi-source pharmaceutical wholesaler networks under cooperative purchasing agreements.
