UNSPSC 51171634: Alvimopan

This classification denotes an opiate antagonist with the molecular formula C25H32N2O4.2H2O, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier 677C126AET, chemically known as glycine, n-((2s)-2-(((3r,4r)-4-(3-hydroxyphenyl)-3,4-dimethyl-1-piperidinyl)methyl)-1-oxo-3-phenylpropyl)-, dihydrate but generally known as alvimopan, which bears US NIH Compound Identifier 5488547. Alvimopan most often comes in simple, anhydrous, and hyrdate forms.

UNSPSC 51171634 Alvimopan is a Commodity code that does not reflect the work actually being solicited under it in recent state and local procurement. The single recent opportunity tagged to this code — Collin County Community Supervision and Corrections Department's RFP 2026-327 for offender specimen collection and drug testing services — involves laboratory-based drug screening and confirmation testing, staffing of collection sites, and management of randomized testing notification systems. This work bears no relationship to alvimopan, a pharmaceutical agent used to accelerate post-operative bowel function recovery. The code appears to be a data-entry or classification error rather than a meaningful category for state and local procurement activity.

Collin County's RFP, due July 23, 2026, seeks a vendor to operate two collection sites in Plano and McKinney, conduct approximately 25,031 annual tests (five-panel and six-panel immunoassay screens with LC/MS/MS or GC/MS confirmation), support oral fluid and hair testing alternatives, and manage an Interactive Voice Response notification system. The contract is valued at approximately $600,000 over two years with three optional one-year renewal periods. The vendor must hold SAMHSA, Texas DPS, or CAP lab certification and will be evaluated on vendor understanding (30 points), firm qualifications (25 points), client references (15 points), cost (30 points), and optional demonstrations and interviews (up to 30 points). This is a Texas county-level procurement with funding from the Texas Department of Criminal Justice, and the anticipated award date is August 10, 2026. No other recent opportunities under this code are present in the source.
