UNSPSC 51141587: Acetazolamide sodium

This classification denotes a diuretic and carbonic anhydrase inhibitor with the molecular formula C4H5N4O3S2.Na, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier 429ZT169UH, chemically known as 1,3,4-thiadiazole-2-sulfonamide, 5-acetamido- but more generally known as acetazolamide sodium, which bears US NIH Compound Identifier 1986. The base compound, Acetazolamide, also comes in forms adipate ethyl ester, methyl, and tri-methyl.

UNSPSC 51141587 Acetazolamide sodium is a Commodity code that describes a specific pharmaceutical product, yet the recent state and local procurement activity tagged under this code does not reflect purchases of acetazolamide. Seminole County, Florida posted IFB 60459723LAS in June 2026 seeking 1,900 units of Naloxone and 800 Safe Drug Deactivation Systems annually—opioid-reversal and drug-disposal products wholly unrelated to acetazolamide sodium, a carbonic anhydrase inhibitor used in ophthalmologic and neurologic applications. The mismatch suggests either a data-tagging error in the source system or that the code's recent activity does not reflect its nominal pharmaceutical scope. State and local buyers do not appear to be using this Commodity code for its intended product classification in current solicitations.

No recent opportunities for acetazolamide sodium procurement are evident in the state and local marketplace under this code. The single recent post (Seminole County's naloxone and drug-deactivation systems IFB with a July 26, 2023 response date, later republished in June 2026) does not support demand signals for acetazolamide itself. Firms pursuing pharmaceutical supply contracts with state and local health departments, corrections systems, or specialty clinics should verify the relevant Commodity codes directly against their target buyers' active RFPs and RFQs rather than rely on this code's recent tagging pattern.
