UNSPSC 51172157: Adiphenine methyl bromide

This classification denotes an antispasmotic agent with the molecular formula C21H28NO2.Br, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier 2OVU84VI37, chemically known as acetic acid, diphenyl-, ester with diethyl(2-hydroxyethyl)methylammonium bromide, but more generally known as adiphenine methyl bromide, which bears US NIH Compound Identifier 197841. European Medicines Agency schedules adiphenine methyl bromide or its base in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB05272MIG.

Most nations, for tariff purposes, schedule adiphenine methyl bromide under HS 29221980. SMILES: CC[N+](C)(CC)CCOC(=O)C(C1CCCCC1)C2CCCCC2.[BR-].

UNSPSC 51172157 Adiphenine methyl bromide is a Commodity code that in recent state and local procurement practice does not align with the chemical's pharmaceutical scope — the sole recent opportunity tagged to this code is Collin County Community Supervision and Corrections Department's RFP 2026-327 for offender specimen collection and drug testing services, a contracting need that involves immunoassay and confirmatory lab testing (LC/MS/MS and GC/MS) but does not procure adiphenine methyl bromide or related pharmaceutical compounds. The Collin County RFP solicits comprehensive drug-testing infrastructure: staffing and facility operations at two collection sites in Plano and McKinney, Interactive Voice Response systems for randomized testing notifications, five-panel and six-panel screening panels, alternative testing modalities including oral fluid and hair analysis, and SAMHSA-certified or CAP-certified lab work, with an estimated contract value of $600,000 over two years plus up to three optional one-year renewals. Evaluation weights vendor understanding (30 points), firm qualifications (25 points), client references (15 points), and cost (30 points), with optional Phase 2 demonstrations scoring up to an additional 30 points. The mismatch between the code name (a specific brominated alkaloid) and the actual work being solicited (broad drug-screening and testing services) suggests either a tagging error in the state and local procurement database or a fundamental misalignment between UNSPSC classification and operational procurement intent in this instance.

The code shows no other recent state and local activity supporting a reliable characterization of issuing-body mix or geographic spread. Collin County, Texas is the sole source of recent opportunity data; the RFP response date was July 23, 2026 with an anticipated award date of August 10, 2026. Given the absence of comparable recent solicitations under this Commodity code, practitioners should evaluate whether this code is actively used in state and local procurement or if the single Collin County posting represents an outlier classification.
