UNSPSC 51171623: Phenolphthalein

This classification denotes an organic carcinogen with the molecular formula C20H14O4, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier 6QK969R2IF, chemically known as 3,3-bis(p-hydroxyphenyl)phthalide but generally known as phenolphthalein, which bears US NIH Compound Identifier 4764. European Medicines Agency schedules Phenolphthalein in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB09773MIG.

UNSPSC 51171623 Phenolphthalein is a Commodity code that does not align with the state and local procurement activity tagged under it. Collin County Community Supervision and Corrections Department's recent RFP 2026-327 for offender specimen collection and drug testing services involves immunoassay and confirmatory testing methodologies (LC/MS/MS, GC/MS, oral fluid, and hair testing), but phenolphthalein — a pH indicator chemical — bears no relationship to the actual scope of work being solicited. The code shows little relevant recent activity under its nominal scope.

The Collin County opportunity is representative of specimen collection and drug testing contracting in the criminal justice supervision context, not chemical procurement. With an estimated contract value of $600,000, annual testing volume of approximately 25,031 tests, and a two-year initial term with three optional one-year renewals, the solicitation emphasizes vendor qualifications (SAMHSA, Texas DPS, or CAP lab certification), staffing two collection sites in Plano and McKinney, and per-test pricing models with no surcharges. The RFP closed July 23, 2026, with award anticipated August 10, 2026. This mismatch between the code assignment and the actual work suggests either a data-entry error or a cataloging anomaly in the sourcing system. Firms pursuing phenolphthalein supply to state and local procurement offices should verify recent activity through direct solicitation searches rather than rely on this code's tagging.
