This classification denotes an antispasmotic agent and antimuscarinic agent with the molecular formulas C28H30N2O2 and C28H30N2O2.BrH, preparations that US FDA regulates as active ingredients or moieties under Unique Ingredient Identifiers APG9819VLM and CR02EYQ8GV, the base compound being chemically known as (s)-1-(2-(2,3-dihydro-5-benzofuranyl)ethyl)-alpha,alpha-diphenyl-3-pyrrolidineacetamide but generally known as darifenacin, which bears US NIH Compound Identifier 72054.

UNSPSC 51172121 Darifenacin or darifenacin hydrobromide is a Commodity code that does not reflect the actual procurement activity currently tagged to it in state and local solicitations. The single recent opportunity on file—Collin County Community Supervision and Corrections Department's RFP 2026-327 for offender specimen collection and drug testing services—concerns immunoassay screening, LC/MS/MS and GC/MS confirmation testing, oral fluid and hair testing methodologies, and lab operations, none of which relate to darifenacin procurement or pharmaceutical supply. The mismatch suggests a classification or tagging error in the source record rather than active state and local demand for this pharmaceutical ingredient through formal procurement channels.

The Collin County RFP, posted September 25, 2026 with a response deadline of July 23, 2026, carries an estimated annual contract value of $600,000 over two years with three optional one-year renewals, and covers specimen collection and testing operations at two sites in Plano and McKinney, Texas. This opportunity is the only recent record available under this code; no other state, county, city, school district, transit authority, or special-purpose district solicitations for darifenacin or related pharmaceutical products appear in the dataset. The code shows little relevant recent activity for darifenacin procurement at the state and local level.
