UNSPSC 51131628: Citric acid

This classification denotes a carboxylic acid with the molecular formula C6H8O7.H2O, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier 2968PHW8QP. European Medicines Agency schedules citric acid in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB12482MIG. The term citric acid monohydrate is a U.S. FDA designation. SMILES: OC(CC(=O)O)(CC(=O)O)C(=O)O.

UNSPSC 51131628 Citric acid is a Commodity code that shows minimal alignment with recent state and local procurement activity. The single recent opportunity tagged to this code — Sourcewell's RFP #061626, posted May 12, 2026 with a June 16, 2026 deadline — solicits law enforcement equipment for a multi-jurisdictional cooperative purchasing vehicle, not chemical compounds or food additives. The mismatch suggests either a tagging error in the source record or that citric acid procurement at the state and local level does not generate frequent solicitation activity visible in current databases.

The law enforcement equipment solicitation itself spans Sourcewell (a Minnesota local government unit and service cooperative), Washington counties including Franklin, Grant, Grays Harbor, Chelan, and Yakima, and is open to governmental agencies, higher education institutions, school districts, nonprofit organizations, tribal governments, and public entities throughout the United States and Canada. However, because this opportunity is unrelated to the code's nominal chemical commodity scope, it provides no signal about actual citric acid procurement patterns or issuing-body preferences under UNSPSC 51131628. The code shows no recent documented demand from state departments, counties, school districts, or other local bodies for citric acid specifically.
