UNSPSC 51161571: Nivimedone sodium

This classification denotes a mast cell stabilizer with the molecular formula C11H8NO4.Na.H2O, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier 4953C873N2, chemically known as 1h-indene-1,3(2h)-dione, 5,6-dimethyl-2-nitro-, ion(1-), sodium, monohydrate but more generally known as nivimedone sodium, which bears US NIH Compound Identifier 43916. Most nations, for tariff and trade purposes, schedule nivimedone sodium under HS 29147000 and SITC 51629. As of Q4 2014, NIVIMEDONE SODIUM remains US FDA's Preferred Term for this commodity.

Nivimedone sodium bears US NLM identifiers UMLS ID C0132621 and NCI Concept Code C72941. SMILES: CC1CC2C(CC1C)C(=O)C(=[N+]([O-])[O-])C2=O.O.[NA+].

UNSPSC 51161571 Nivimedone sodium is a Commodity code for a pharmaceutical active ingredient with no recent state and local procurement activity visible in available records.

The code represents a specialized pharmaceutical compound used in pharmaceutical manufacturing and formulation. State and local government purchases of active pharmaceutical ingredients at this level of specificity are rare outside of state health departments, state hospital systems, and specialized correctional or mental-health facilities that maintain in-house pharmaceutical compounding operations. The absence of recent solicitations under this code suggests either minimal demand from state and local buyers for this particular ingredient, sourcing through higher-level pharmaceutical supply contracts indexed to broader UNSPSC families, or procurement activity that is not publicly visible in standard state and local notice databases. Business development professionals should verify whether this ingredient appears in state or local pharmacy benefit manager agreements, group purchasing organization (GPO) contracts, or cooperative purchasing vehicles that may aggregate pharmaceutical inputs under parent codes rather than commodity-level specifications. If pursuing activity in this space, direct outreach to state Medicaid programs, state health department procurement offices, and state hospital system purchasing departments may yield more actionable intelligence than monitoring routine RFP and RFQ channels.
