UNSPSC 12161504: Sulfhydryl reagents

UNSPSC 12161504 Sulfhydryl reagents, a Commodity code, sees limited recent state and local activity focused on clinical and forensic laboratory operations. The posted opportunities reveal that state and local governments buy these reagents as components of broader laboratory service contracts, diagnostic testing programs, and forensic DNA analysis systems rather than as standalone consumables. Collin County Community Supervision and Corrections Department's RFP for offender drug testing services (RFP 2026-327, due July 23, 2026, estimated value $600,000) encompasses immunoassay screening with LC/MS/MS or GC/MS confirmation—detection methodologies that rely on sulfhydryl-based chemistry. Mississippi Department of Mental Health's sole-source notice for FDA-cleared Clozapine Test Kits (notice issued September 16, 2026, objection window through September 30, 2026) and San Bernardino County's ITB for laboratory supplies including reagents (ITB DPHE26-DM-6460, due July 31, 2026) similarly integrate these reagents into diagnostic workflows. Oregon State Police's five-year sole-source procurement for Promega PowerPlex Y23 forensic DNA amplification kits ($250,000 estimated value, protest deadline July 31, 2026) demonstrates demand in forensic applications. Issuing bodies span county community supervision departments, state health agencies, county public health departments, and law enforcement, with Collin County appearing twice in recent notices.

Recent activity concentrates in Texas, Mississippi, Oregon, California, and the District of Columbia. Collin County Health Care Services' IFB for comprehensive laboratory services (IFB 2025-166, due October 2, 2025, estimated annual value $70,000) and Cobb County School District's science supplies procurement (IFB B26128, due June 16, 2026, estimated annual value $175,000) show laboratory reagent demand across public health, criminal justice, and education sectors. The code shows sparse standalone visibility; most recent opportunities integrate reagents as line-item inputs within larger diagnostic or testing service contracts rather than as primary procurement drivers. Sole-source designations appear in both the Clozapine kits and DNA amplification kit notices, signaling established supplier relationships and specialized validation requirements that constrain competition.
