The U.S. Department of Agriculture (USDA) Animal and Plant Health Inspection Service (APHIS) awarded a $31,500.00 firm-fixed-price purchase order to Southwest Research Institute (SwRI), a non-profit research organization, to conduct a preliminary (5-batch) analysis study on a manufacturing source of the active ingredient sodium nitrite. This study will characterize the sodium nitrite, the major impurity sodium nitrate, and loss on drying for each of the 5 batches, in accordance with Federal Insecticide, Fungicide, and Rodenticide Act (FIFRA) Good Laboratory Practices (GLPs). SwRI will also produce GLP-compliant Certificates of Analysis for the sodium nitrite and sodium nitrate reference standards. The work will be performed in San Antonio, Texas, and the final report is due by December 31, 2025. This award is not associated with a set-aside or an Indefinite Delivery Vehicle (IDV) contract.
