UNSPSC 51171651: Phenolphthalein glucuronide

This classification denotes an organic carcinogen with the molecular formula C26H22O10, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier 0S390I6642, chemically known as .beta.-d-glucopyranosiduronic acid, 4-(1,3-dihydro-1-(4-hydroxyphenyl)-3-oxo-1-isobenzofuranyl)phenyl, but more generally known as phenolphthalein glucuronide, which bears US NIH Compound Identifier 3032634.

European Medicines Agency schedules phenolphthalein glucuronide or its base in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB09773MIG. Most nations, for tariff purposes, schedule phenolphthalein glucuronide under HS 29322910. SMILES: C1CCC2C(C1)C(=O)OC2(C3CCC(CC3)O)C4CCC(CC4)O[C@H]5[C@@H]([C@H]([C@@H]([C@H](O5)C(=O)O)O)O)O.

UNSPSC 51171651 Phenolphthalein glucuronide is a Commodity code that in recent state and local procurement activity labels drug-testing services rather than the chemical reagent its nominal name suggests. Collin County Community Supervision and Corrections Department's RFP 2026-327 for offender specimen collection and drug testing services is tagged under this code, though the scope encompasses staffing, immunoassay screening with LC/MS/MS or GC/MS confirmation, electronic reporting, and alternative methodologies including oral fluid and hair testing — a full-service testing operation rather than a single chemical input. The work involves operating collection sites and an Interactive Voice Response notification system, maintaining SAMHSA or Texas DPS lab certification, and delivering approximately 25,031 tests annually across five-panel and six-panel screening panels with confirmation capability. State and local governments appear to acquire these services through community supervision departments and corrections agencies seeking to outsource specimen collection and drug-testing operations.

Collin County's RFP 2026-327 represents the primary recent activity under this code, posted September 25, 2026 with proposals due July 23, 2026 at 2:00 p.m., estimated contract value of $600,000, a two-year term commencing September 1, 2026 with three optional one-year renewals, and an anticipated award date of August 10, 2026. The solicitation uses a two-phase evaluation structure weighting vendor understanding and qualifications at 55 points, client references at 15 points, and cost at 30 points, with optional phase-two demonstrations and interviews worth up to 30 additional points. The county reserves the right to award in whole or in part to multiple vendors. Pricing submission is on a per-test basis across three service models: screening only, confirmation after screening, and screening with automatic confirmation of positives, with all costs including freight, delivery, insurance, and staffing baked into the per-test rate and no additional surcharges permitted.
