UNSPSC 51143908: Pyridoxine disulfide or pyrithioxine or pyritinol

This classification denotes a cns stimulant with the molecular formula C16H20N2O4S2, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier AK5Q5FZH2R, chemically known as 3,3-(dithiodimethylene)bis(5-hydroxy-6-methyl-4-pyridinemethanol) but more generally known as pyrithioxine, which bears US NIH Compound Identifier 14190. European Medicines Agency schedules Pyritinol in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB10175MIG.

The term PYRITINOL is an International Non-Proprietary Name or INN (see World Health Organization INN reference publication, Volume 19 1975, List 5). World Health Organization schedules pyrithioxine in its Anatomical Therapeutic Chemical (ATC) Classification. SMILES: CC1=NC=C(C(=C1O)CO)CSSCC2=CN=C(C(=C2CO)O)C.

UNSPSC 51143908 Pyridoxine disulfide or pyrithioxine or pyritinol is a Commodity code that nominally covers pharmaceutical compounds used in neurological and cognitive applications. However, the recent state and local procurement activity tagged under this code shows a significant mismatch: Seminole County, Florida solicited naloxone and drug deactivation systems — opioid-overdose reversal agents and harm-reduction equipment — which fall outside the nominal scope of the pyridoxine-family compounds the code describes. State and local governments appear to use this code inconsistently or incorrectly when tagging pharmaceutical and medical-device procurements. The issuing activity under this code is sparse and geographically narrow.

The single recent opportunity on record is Seminole County's IFB 60459723LAS, posted June 30, 2026, with a response deadline of July 26, 2026, seeking 1,900 units of naloxone and 800 safe drug deactivation systems annually for quarterly delivery to the Seminole County Community Health Building in Sanford, Florida. The county required electronic bid submission through its e-Procurement Portal, unit pricing for each line item, drug-free workplace certification, E-Verify compliance, and standard insurance coverage. The initial contract term was two years with a one-year renewal option and a three-month probationary period. The procurement noted potential FEMA funding with associated federal compliance requirements. Beyond this single Seminole County solicitation, no other recent state and local opportunities appear under this code. The classification suggests either limited use of this code within state and local procurement systems or systematic tagging misalignment between the code's nominal pharmaceutical scope and the medical-device and public-health acquisitions actually being purchased.
