Mono (3-carboxypropyl) phthalate (MCPP) is a metabolite of Di-n-octyl phthalate (DnOP), which is utilized as a plasticizer in the production of polyvinyl chloride plastics, cellulose esters, and polystyrene resins.

Oleanolic acid-3-O-glucosyl(1-2)xylyl(1-3)glucosiduronic acid is a naturally occurring triterpene saponin found in various medicinal plants. Its structure features an oleanolic acid aglycone conjugated to a complex oligosaccharide chain containing glucose, xylose, and glucuronic acid. In analytical chemistry, this compound serves as a representative molecule for studying the sorption kinetics of saponins on functional materials like hypercrosslinked polystyrene. Biologically, like many oleanane-type saponins, it is investigated for its potential anti-inflammatory, hepatoprotective, and antitumor activities.

1. Ginkgolic acid C17:1 can significantly inhibit enterohemorrhagic Escherichia coli O157:H7(EHEC) biofilm formation on the surfaces of polystyrene and glass, and on nylon membranes.

Poly(styrenyl acetal trehalose) (pSAT) is synthesized by linking trehalose side chains to a polystyrene backbone through acetal bonds. This compound stabilizes various proteins and enzymes against temperature fluctuations without triggering an innate immune response. Additionally, Poly(styrenyl acetal trehalose) can be utilized in synthesizing protein-polymer conjugates, thereby reducing the renal clearance of active molecules.
