UNSPSC 51283304: Cycloserine tartrate

This classification denotes an antitubercular agent with the molecular formula C4H6O6.C3H6N2O2, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier 24EZ3L1E6S. Most nations, for tariff and trade purposes, schedule cycloserine tartrate under HS 29419000. As of Q4 2014, CYCLOSERINE TARTRATE remains US FDA's Preferred Term for this commodity. SMILES: C1[C@H](C(=O)NO1)N.[C@@H]([C@H](C(=O)O)O)(C(=O)O)O.

UNSPSC 51283304 Cycloserine tartrate is a Commodity code for a specific pharmaceutical active ingredient, yet recent state and local opportunities tagged under it do not reflect purchases of cycloserine tartrate itself. Instead, the code appears in state and local procurement systems as a miscategorization or system artifact; the actual solicitations under this code involve unrelated pharmaceutical products and medical supplies. The Illinois Department of Public Health awarded a piggyback pharmaceutical warehouse contract through MMCAP Infuse to Chartwell Rx LLC for Doxycycline Hyclate and Ciprofloxacin Hydrochloride tablets, neither of which is cycloserine tartrate. Seminole County, Florida solicited Naloxone and Safe Drug Deactivation Systems, products wholly outside the scope of this Commodity code's nominal definition. State and local procurement offices are using this code to tag pharmaceutical and medical-supply buys more broadly, disconnected from the specific active pharmaceutical ingredient the code nominally describes.

The mismatch between the code's narrow pharmaceutical definition and the actual work being bought limits utility for vendors specializing in cycloserine tartrate. Geographic activity centers on Illinois and Florida based on recent postings, though the sample size is too small to characterize a meaningful pattern. The Illinois Department of Public Health's MMCAP Infuse piggyback award (completed August 28, 2026, $2,999,999.11 over three years) and Seminole County's IFB for Naloxone and deactivation systems (posted June 30, 2026, response deadline July 26, 2026) represent the only recent opportunities visible under this code, and neither is directly relevant to cycloserine tartrate procurement. Vendors should verify actual commodity codes with issuing bodies before pursuing opportunities tagged under 51283304, as the code does not reliably signal demand for this specific pharmaceutical product in state and local markets.
