UNSPSC 51181628 Protirelin tartrate is a Commodity code representing a pharmaceutical product — a synthetic thyrotropin-releasing hormone (TRH) analog used in diagnostic and therapeutic applications in clinical settings. State and local governments procure this agent primarily through their health departments, public health agencies, hospital systems, and correctional health services to support diagnostic testing protocols, particularly thyroid function assessment and pituitary hormone stimulation testing. The product is typically acquired as a finished pharmaceutical in injectable form, often through standing contracts or cooperative purchasing agreements negotiated at the state level or through group purchasing organizations (GPOs) serving public health systems.

No recent state or local contract opportunities are currently posted under this Commodity code. The source provides no record of issuing bodies, geographic activity, notice types, response dates, or representative solicitations. Protirelin tartrate procurement by public entities tends to be routine and consolidated within larger pharmaceutical or diagnostic-reagent contracts rather than solicited as a standalone line item; activity under this code remains either inactive in current public notice databases or absorbed into broader health-services or pharmaceutical-supply procurements tagged at higher UNSPSC tiers.
