Nonyl Phenol

CAS Number:25154‑52‑3 (mixed isomer nonylphenols; 4‑n‑nonylphenol is CAS 104‑40‑5)

Synonyms:Phenol, nonyl‑; branched nonylphenol

Chemical Formula:C₁₅H₂₄O

Product Introduction

Nonylphenol is a viscous, pale yellow liquid with a slight phenolic odor. Known for its strong surfactant properties, it is used in resin stabilizers, lubricating oil additives, and as a precursor for nonylphenol ethoxylates. However, it is recognized as an endocrine disruptor and restricted in many regions.
