PNA-10 CARBOXYETHYL FLUORENE
Safety score · 0–100
Moderate
Derived from EU CosIng regulatory status, PubChem hazard data and published research. How we score.
The longest member of the PNA-carboxyethyl fluorene family in this batch — 20 nucleobases across seven different nucleobase types. Same novel-polymer caveat as the rest of the PNA series — sparse public data keeps it parked in orange.
