UNSPSC 51432405 Captopril disulfide is a Commodity code covering pharmaceutical active ingredients and intermediate compounds used in emergency medical and clinical settings. State and local governments procure under this code primarily through fire rescue departments, EMS agencies, and public health systems that stock advanced life support and emergency medications. The City of Tampa's recent solicitation for Advanced Life Support Medications illustrates the actual scope: municipalities buy specific pharmaceutical line items in measured unit quantities for immediate clinical deployment, with strict requirements around expiration dating, shelf-life warranties, and rapid replacement protocols. Issuing bodies include municipal purchasing departments acting on behalf of fire rescue and emergency services operations; the code sees activity from city governments with established emergency medical response infrastructure rather than county or state-level health procurement.

The most recent opportunity posted in April 2026 is the City of Tampa Purchasing Department's IFB 26-P-00188 for Advanced Life Support Medications, due April 8, 2026, with a contract value of $40,000 and a one-year base term plus two one-year renewal options. The solicitation specified four medication line items totaling roughly 3,550 units (Labetalol HCI, Epinephrine, Adenosine, and Diltiazem in various strengths and quantities) with nine-month minimum expiration dating, ten-calendar-day delivery, and 365-day defect warranty. The award carried a 5 percent bid discount for Small Local Business Enterprise participation (capped at $10,000), and required Safety Data Sheets compliant with OSHA standards and WCAG 2.2 Level AA accessibility documentation. Geographic activity under this code remains concentrated in Florida based on recent posting volume; additional state and local opportunities in other jurisdictions were not present in the source data.
