Linuron

About Linuron

Linuron is an API reference standard carrying the CAS registry number 330-55-2. Formula C9H10Cl2N2O2, molecular weight 249.09 g/mol. The IUPAC name is 3-(3,4-dichlorophenyl)-1-methoxy-1-methylurea. Alternative names: Afalon inuron and Herbicide 326.

The product is provided as a solid. Keep the vial tightly closed, protected from light and humidity, at the temperature stated on the Certificate of Analysis. The GHS classification uses the signal word “Danger”, so appropriate gloves, eye protection and ventilation are recommended.

Laboratories use this the parent drug substance standard for identity and assay testing, system suitability checks and method validation supporting ANDA and DMF filings. Buyers come mainly from pharmaceutical manufacturing and academic and industrial research.

Available in 10 mg, 25 mg, 50 mg and 100 mg packs, Linuron is dispatched with a Certificate of Analysis (COA) to destinations worldwide.
