UNSPSC 12161504: Sulfhydryl reagents

UNSPSC 12161504 Sulfhydryl reagents (Commodity) covers chemical reagents used in laboratory diagnostics, forensic analysis, and clinical testing. State and local governments solicit these materials primarily through public health laboratories, forensic departments, and educational institutions that run diagnostic or research operations. The recent opportunities show purchasing concentrated in clinical laboratory operations—culture media, stains, reagents, and diagnostic test materials for public health agencies—and specialized forensic and drug-testing applications where confirmatory chemical analysis is required. San Bernardino County Department of Public Health issued an ITB for laboratory supplies encompassing reagents and diagnostic materials (ITB DPHE26DM6460, due July 31, 2026), while Collin County Community Supervision and Corrections Department solicited offender drug-testing services requiring LC/MS/MS and GC/MS confirmation chemistry (RFP 2026-327, due July 23, 2026, estimated contract value $600,000). School districts and universities also purchase chemistry supplies and samples for laboratory instruction and research, as demonstrated by Cobb County School District's procurement of science chemicals and supplies (IFB B26128, due June 16, 2026, estimated annual expenditure $175,000) and University of Wisconsin-Madison's request for urinalysis samples (RFB 2026-UWMSN-01304-RFB, due May 8, 2026).

Activity under this code is concentrated in California, Texas, Georgia, and the District of Columbia, with secondary activity in Mississippi and Wisconsin. County health departments and corrections agencies represent the highest-volume buyers; school districts and public universities form a steady secondary market. The District of Columbia Department of Finance and Services has posted multiple laboratory consumables and reagent solicitations (RK322208 for Agilent instrument consumables in April 2026, RK324433 for NGS supplies in May 2026, and RK324618 for general consumables in June 2026), suggesting sustained procurement demand across forensic and public health testing. University of Southern Mississippi procured hexafluoroglutaryl fluoride (300 kg, 98% purity) via sealed bid (IFB 9280-26-R-IFBD-00028, due February 26, 2026), indicating specialized chemical sourcing for research or industrial laboratory use. Typical response windows are 7–37 days, with most public health and school district opportunities offering 30+ days for bid preparation. Payment terms commonly run net 30–60 days; contracts often span one to five years with firm pricing requirements and quarterly or annual reporting obligations.
