UNSPSC 51171529: Betaine hydrate

This classification denotes a nutritional supplement with the molecular formula C5H11NO2.H2O, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier TPU0ITR2BR, chemically known as 1-carboxy-n,n,n-trimethylmethanaminium, chloride but more generally known as betaine hydrate, which bears US NIH Compound Identifier 248.

UNSPSC 51171529 Betaine hydrate is a Commodity code, but the recent state and local activity tagged under it reflects drug-testing services rather than chemical procurement. Collin County Community Supervision and Corrections Department posted RFP 2026-327 in September 2026 for offender specimen collection and drug testing services, a scope that encompasses staffing, lab analysis, and reporting infrastructure rather than betaine hydrate as a reagent or consumable. The mismatch between the code's nominal scope and the actual work being solicited suggests either a tagging error in the state system or that betaine hydrate functions as an ancillary input to the testing methodologies named in the RFP, but the source does not clarify this relationship. State and local procurement under this code shows no recent activity unambiguously tied to betaine hydrate procurement itself.

The single recent opportunity identified is Collin County's RFP for drug-testing services with a response date of July 23, 2026 and an estimated contract value of $600,000 over two years with three optional one-year renewals. The work involves operating two collection sites in Plano and McKinney with approximately 25,031 annual tests using immunoassay screening and LC/MS/MS or GC/MS confirmation, along with oral fluid and hair testing options. Lab certification from SAMHSA, TX DPS, or CAP is required, and pricing is structured on a per-test basis across three service models with no additional surcharges permitted. No other state or local jurisdictions appear in the recent-opportunities record for this code, making geographic concentration impossible to characterize beyond the single Collin County posting in Texas.
