UNSPSC 51441605 Methacholine is a Commodity code that does not map to the recent state and local opportunities posted under it. The four most recent opportunities solicited under this code span radiologic and X-ray equipment procurement and installation, extended warranty coverage for specialized X-ray systems, maintenance services for proprietary X-ray inspection equipment, and chemical supplies (copper sulfate). None of these solicitations involve methacholine or related pharmaceutical or diagnostic agents. The mismatch suggests either miscoding by issuing bodies or inconsistent application of the UNSPSC taxonomy in state and local procurement systems. No recent opportunities for methacholine itself appear in the active solicitation record.

The opportunities that were posted under this code originate from county-level issuing bodies in Florida and Arizona. Maricopa County issued an IFB for radiologic equipment and installation services due October 22, 2026; Escambia County Correction solicited an extended warranty for X-ray machines under sole-source procurement (due August 19, 2026); Broward County Aviation Department issued an RFI (due July 28, 2026) contesting a sole-source designation for Rapiscan X-ray system maintenance; and Pasco County issued an RFQ for copper sulfate supply on an as-needed basis (due June 26, 2026). Given the absence of activity aligned with the code's stated scope and the wide divergence among the opportunities posted, this code does not present a reliable market signal for business development purposes.
