UNSPSC 51111658: Tiazofurin or tiazofurine

This classification denotes a purine antagonist and inosine monophosphate dehydrogenase inhibitor with the molecular formula C9H12N2O5S, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier ULJ82834RE, chemically known as 4-thiazolecarboxamide, 2-.beta.-d-ribofuranosyl- but generally known as tiazofurin, which bears US NIH Compound Identifier 323701. European Medicines Agency schedules Tiazofurin in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB27111.

UNSPSC 51111658 Tiazofurin or tiazofurine is a Commodity code for a specific antiviral pharmaceutical agent, but state and local procurement activity under this code shows minimal relevant recent solicitation. The Texas Health and Human Services Commission posted a Request for Information (RFI) in April 2026 tagged to this code; however, the RFI concerns a broad Therapeutic Pharmacy Initiative seeking vendor capability information about direct-to-manufacturer prescription programs and pharmacy benefit management, not procurement of tiazofurin itself. The RFI solicits vendor experience with direct contracting models, negotiated net pricing, and outcomes-based agreements for prescription fulfillment across multiple drug categories and therapeutic needs, rather than a single active pharmaceutical ingredient.

The April 2026 RFI from the Texas HHS Commission represents exploratory market intelligence gathering ahead of formal procurement, with no award value, budget range, or specific drug-product quantities identified. No additional recent state or local contract opportunities under this code appear in the current source. The code does not reflect active purchasing of tiazofurin by state health departments, Medicaid programs, or other state and local entities in the recent record. Business development professionals should monitor whether Texas HHS issues a follow-on RFP with explicit pharmaceutical procurement scope, but current activity does not support immediate pursuit under this specific commodity code.
