UNSPSC 51182405: Dibase calcium phosphate

This classification denotes a calcium phosphate and calcium supplement with the molecular formula Ca.HO4P, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier L11K75P92J, chemically known as phosphoric acid, calcium salt (1:1) but generally known as calcium phosphate, dibasic, which bears US NIH Compound Identifier 24441. European Medicines Agency schedules Calcium phosphate, dibasic in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB13192MIG. SMILES: OP(=O)([O-])[O-].[CA+2].

UNSPSC 51182405 Dibase calcium phosphate is a Commodity code with minimal recent state and local procurement activity tied to its nominal scope. The single recent opportunity posted under this code—Collin County Community Supervision and Corrections Department RFP 2026-327 for offender specimen collection and drug testing services—bears no meaningful connection to dibase calcium phosphate procurement. The RFP solicits laboratory testing staffing, specimen collection site operations, immunoassay and confirmatory drug screening (LC/MS/MS or GC/MS), and electronic result reporting for approximately 25,031 annual tests across two Texas facilities. The scope includes staffing two collection sites in Plano and McKinney, operating an Interactive Voice Response notification system, conducting five-panel and six-panel drug screens with alternative methodologies (oral fluid and hair testing), and maintaining SAMHSA, TX DPS, or CAP laboratory certification. Pricing is structured on a per-test basis across three service models—screening only, confirmation after screening, and screening with automatic confirmation of positives—with a contract value of $600,000 over two years (September 1, 2026 through August 31, 2028) plus three optional one-year renewals.

The code shows no relevant recent activity among state and local buyers. The mismatch between the nominal code scope (a pharmaceutical ingredient for dental or nutritional applications) and the actual work being solicited (criminal-justice drug testing services) suggests either a tagging error or that the code is simply inactive in state and local procurement. Buyers evaluating opportunities under this code should verify directly with jurisdictions and cooperative purchasing consortia whether dibase calcium phosphate appears in active solicitations, as the recent opportunity record does not support meaningful pipeline development at this time.
