UNSPSC 51111600: Antimetabolites

This classification denotes drugs that are chemically similar to naturally occurring metabolites, but differ enough to interfere with normal metabolic pathways.

UNSPSC 51111600 Antimetabolites, a Class code, encompasses chemotherapy agents and related pharmaceutical products that state and local health systems, correctional facilities, and public hospital networks procure for cancer treatment and inmate medical care. The code covers active pharmaceutical ingredients and finished formulations—including methotrexate, fluorouracil, gemcitabine, and related compounds—that public health authorities source through both direct procurement and cooperative purchasing agreements. State departments of health, county hospital systems, and state corrections departments are the primary buyers, often consolidating purchases across multiple facilities to achieve volume discounts and ensure consistent supply chains for oncology programs and institutional pharmacy operations.

The source materials provided contain no recent state or local contract opportunities tagged to this code, limiting visibility into current geographic concentration or representative solicitation activity. Without posted RFP, RFQ, IFB, or ITB notices in the recent-opportunities block, no decision-relevant intelligence on response dates, issuing bodies by jurisdiction, or active procurement timelines can be drawn. Firms pursuing this code should monitor state health department procurement portals, cooperative purchasing networks serving public hospitals (such as state purchasing cooperatives or regional health consortiums), and correctional-system pharmacy RFPs directly, as antimetabolite procurement often occurs through standing agreements and non-competitive renewals rather than competitive open solicitations.
