UNSPSC 51171627: Potassium sodium tartrate

This classification denotes a laxative with the molecular formula C4H4O6.K.Na.4H2O, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier QH257BPV3J, chemically known as 2,3-dihydroxybutanedioic acid, monopotassium monosodium salt but generally known as potassium sodium tartrate, which bears US NIH Compound Identifier 9357. European Medicines Agency schedules Potassium sodium tartrate in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB12561MIG.

As of Q4 2014, POTASSIUM SODIUM TARTRATE remains the US FDA Preferred Term for this commodity. Potassium sodium tartrate bears US NLM identifiers UMLS ID C0770985 and NCI Concept Code C80954. SMILES: [C@@H]([C@H](C(=O)[O-])O)(C(=O)[O-])O.[Na+].[K+].

UNSPSC 51171627 Potassium sodium tartrate is a Commodity code that in state and local practice encompasses laboratory and pharmaceutical chemical reagents, precipitants, and analytical standards used in water testing, forensic analysis, and quality-control applications across municipal utilities, state health departments, and university research facilities. Recent solicitations under this code and closely related chemical procurement activity show state and local governments buying specialized laboratory consumables including precipitant solutions for analytical chemistry, water treatment chemicals meeting NSF and AWWA certification, drug reference standards for forensic testing, and diagnostic reagents for microbial detection in drinking water and wastewater programs. Issuing bodies span municipal water utilities (City of Meriden, City of Tampa, City of Palm Bay), state environmental and health laboratories (California Department of Justice, District of Columbia Department of Forensic Sciences), county sheriff and public health agencies (Harris County, Santa Clara County), and public university research divisions (Texas A&M University). The solicitations reflect a mix of commodity procurement (bulk water treatment chemicals), specialized brand-specific reagents (Sigma-Aldrich drug standards, IDEXX filtration products, Shiga Toxin QuikChek kits), and related laboratory consumables supporting compliance with EPA and state environmental protection standards.

Geographic activity clusters in Texas (Texas A&M University ITB for precipitant solutions due July 15, 2026; Harris County ITB for crime scene and forensic supplies due June 8, 2026), California (State RFB for Sigma-Aldrich drug standards, RFB for alcohol USP), the District of Columbia (Department of Finance and Services solicitations for laboratory consumables and forensic instrument supplies with five-to-six-day response windows), and Florida (City of Meriden ITB for water treatment chemicals due June 25, 2026; City of Tampa single-source for IDEXX filtration products; City of Palm Bay ITB for laboratory testing services with historical annual spending of $66,000–$95,000). The code shows steady recent activity, though posted opportunities often do not specify potassium sodium tartrate by name; instead, state and local buyers tag broader chemical and reagent procurements with this commodity code when sourcing mixtures, standards, or precipitants used in water quality, pharmaceutical testing, or forensic analysis workflows.
