CAS 2706-90-3 — Perfluoropentanoic acid

Perfluoropentanoic acid (CAS 2706-90-3) is a fully fluorinated carboxylic acid used primarily as a precursor in the synthesis of fluorinated surfactants, pharmaceutical intermediates, and specialty polymers. PFAS use inventories also record it in anti-reflective coatings for semiconductor manufacturing, cosmetic formulations, carpets and floor coverings, and food-contact paper packaging. It is also employed in the manufacture of fluorinated monomers and as a reagent in organic fluorination chemistry. This compound has the molecular formula C5HF9O2 and a molecular weight of 264.0459 g/mol. It is stable under ambient storage conditions and carries no signal word under standard hazard classifications. Molekula supplies Perfluoropentanoic acid from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
