UNSPSC 51191916: Dihydrotachysterol

This classification denotes a vitamin d analog with the molecular formula C28H46O, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier R5LM3H112R, chemically known as 9,10-secoergosta-5,7,22-trien-3-ol, (3beta,5e,7e,10alpha,22e)- but generally known as dihydrotachysterol, which bears US NIH Compound Identifier 5281010. European Medicines Agency schedules Dihydrotachysterol in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB07141MIG. The term DIHYDROTACHYSTEROL is an International Non-Proprietary Name.

UNSPSC 51191916 Dihydrotachysterol is a Commodity code that in recent state and local solicitation activity actually covers pharmaceutical and chemical supply procurement for government operations, though the recent opportunities show minimal direct alignment with the nominal dihydrotachysterol scope. The City of Meriden solicited sodium bisulfite chemical supply for water treatment operations at a municipal water pollution control facility under IFB B027-15 (due July 29, 2026), and the Minnesota Multistate Cooperative Purchasing Alliance (MMCAP), administered by the Minnesota Department of Administration's Office of State Procurement, issued an RFP for generic multi-source pharmaceuticals and over-the-counter products to be distributed across participating state and local government facilities in Minnesota and Oregon (due March 26, 2026). Both solicitations require substantial insurance coverage, compliance with federal regulatory standards (FDA requirements and Drug Supply Chain Security Act compliance in the pharmaceutical case; Connecticut statutory workers' compensation and liability standards in the chemical case), and fixed or competitive pricing structures evaluated on a unit-cost or price-competitiveness basis.

The issuing bodies mix municipal water utilities with state-level cooperative purchasing alliances administering multi-jurisdictional procurement. Geographic activity includes Connecticut and Minnesota with broader regional reach through the MMCAP cooperative framework extending to Oregon. The chemical procurement from Meriden required performance and payment bonds with firm pricing for the contract term, while the MMCAP pharmaceutical RFP established a two-year initial contract term with optional extensions through June 30, 2028 for incumbents and structured pricing evaluation weighted 75 percent on price competitiveness. Vendors must maintain authorized wholesaler relationships and demonstrate cGMP and DSCSA compliance for pharmaceutical products. The code shows limited recent activity directly matching dihydrotachysterol procurement; the tagged opportunities reflect broader chemical and pharmaceutical supply categories rather than the specific vitamin D metabolite the code nominally describes.
