UNSPSC 51201517: Guanidine

This classification denotes a natural amine with the molecular formula CH5N3, a preparation that US FDA regulates as an active ingredient or moiety under Unique Ingredient Identifier JU58VJ6Y3B, chemically known as 594-14-9 (sulfate, 2:1) but generally known as guanidine, which bears US NIH Compound Identifier 3520. European Medicines Agency schedules Guanidine in its eXtended EudraVigilance Medicinal Product Dictionary or XEVMPD under Index SUB14034MIG. Most nations schedule guanidine under HS 29252900 and SITC 51482.

As of Q4 2014, GUANIDINE remains the US FDA Preferred Term for this commodity. Guanidine bears US NLM identifiers UMLS ID C0120446 and NCI Concept Code C77851. SMILES: NC(=N)N.

UNSPSC 51201517 Guanidine, a Commodity code, does not reflect the actual scope of work state and local governments are procuring under this classification. Recent solicitations tagged to this code center instead on forensic and clinical laboratory consumables, reagents, and diagnostic testing kits—including DNA sequencing supplies, drug screening materials, Shiga Toxin test kits, and Next-Generation Sequencing components—rather than guanidine chemical compounds. The issuing bodies span state health and forensic laboratories (Texas Department of Public Safety, District of Columbia Department of Forensic Sciences, California Department of Public Health), county public safety (Harris County Sheriff's Office), municipal water utilities (City of Arlington, City of Meriden), and higher education (Texas A&M University). Texas and California dominate recent activity, with the District of Columbia representing federal-district procurement and a smaller number of county and municipal opportunities elsewhere. Work is solicited through ITB, RFQ, and RFB vehicles, typically with firm fixed pricing, multi-year terms with renewal options, and delivery schedules tied to usage patterns or standing requirements.

The Texas Comptroller of Public Accounts posted IFB 304T-27-175A11 on September 23, 2026, for proprietary DNA analysis and drug screening consumables (genetic analyzer components, sequencing kits, RapidHIT cartridges, and ELISA kits from Life Technologies, Promega, Qiagen, Immunalysis, and ANDE Corporation) with bids due October 20, 2026, serving the Texas Department of Public Safety and Parks and Wildlife statewide. The State of California issued RFB-IS-27200197 on September 21, 2026, for Shiga Toxin QuikChek diagnostic kits with a Certified Business Enterprise requirement, bids due October 7, 2026. The City of Arlington, Texas, solicited laboratory supplies and chemicals for its water utilities and laboratory services under IFB 270018 (bids due September 17, 2026), and the City of Meriden, Connecticut, requested water treatment chemicals including caustic soda, aluminum sulfate, and sodium permanganate under ITB B026-55 (bids due June 25, 2026, with U.S. manufacturing compliance and Connecticut vendor preference). Harris County, Texas, sought crime scene and forensic supplies including DNA swabs and collection kits under ITB 250415 (bids due June 8, 2026). The mismatch between the code name and recent procurement activity suggests this Commodity code may be misconfigured in the state and local taxonomy system or applied inconsistently across jurisdictions.
