UNSPSC 12162213: Phenolic antioxidant

A phenolic antioxidant is a type of chemical compound that belongs to the phenolic class of compounds. The structure of their molecules enables them to donate hydrogen atoms to free radicals, neutralizing their harmful effects. Phenolic antioxidant reacting with a variety of free radicals. The mechanism of antioxidant actions involved either by hydrogen atom transfer, transfer of a single electron, sequential proton loss electron transfer, and chelation of transition metals.

UNSPSC 12162213 Phenolic antioxidant is a Commodity code covering chemical additives used to prevent oxidation in materials and products. State and local governments procure phenolic antioxidants primarily for inclusion in lubricants, fuels, plastics, and rubber compounds used across transportation fleets, maintenance operations, and infrastructure projects. The code attracts solicitations from state departments of transportation, public works agencies, county maintenance facilities, and municipal fleet operations that specify phenolic antioxidant formulations as performance requirements within larger material or product procurements rather than as standalone chemical purchases. Issuing bodies typically embed these specifications in RFPs and RFQs for finished goods — motor oils, hydraulic fluids, sealants, and protective coatings — rather than issuing direct bids for bulk chemical supplies.

The source provided contains no recent state and local contract opportunities tagged to this code, making it difficult to characterize current geographic concentration or to name representative recent solicitations with issuing bodies and response dates. Without posted opportunities, the code shows no visible activity in the recent procurement marketplace that would support a pursue or watch recommendation at this time.
