Nonylphenol (NP) is a key organic intermediate widely used in the production of surfactants, antioxidants, and specialty additives. As a reliable chemical supplier, we provide high‑purity nonylphenol (CAS 25154‑52‑3) in various grades to meet the diverse needs of industries worldwide.

Product Overview

Chemical name: Nonylphenol (mixed isomers)

CAS No.: 25154‑52‑3 (common); 104‑40‑5 (4‑nonylphenol)

Appearance: pale yellow to colourless liquid

Purity: ≥ 99.0% (typical)

Molecular weight: 220.35 g/mol

Our nonylphenol is produced under strict quality control, with low colour, low moisture, and consistent isomer distribution, ensuring reliable performance in downstream processes.

Key Industrial Applications

Nonylphenol serves as a versatile building block for:

Nonylphenol ethoxylates (NPEs) – the largest use, as non‑ionic surfactants in detergents, emulsifiers, and wetting agents.

Antioxidants and stabilisers – for plastics, rubbers, and lubricants.

Pesticide emulsifiers – improving dispersion and efficacy of agrochemicals.

Textile and leather auxiliaries – providing wetting, scouring, and levelling properties.

Metalworking fluids – as corrosion inhibitors and lubricity enhancers.

Its branched alkyl chain offers excellent hydrophobicity, making it ideal for oil‑water interfacial applications.
