Diflubenzuron

About Diflubenzuron

Diflubenzuron is an API reference standard carrying the CAS registry number 35367-38-5. Formula C14H9ClF2N2O2, molecular weight 310.68 g/mol. Systematically, it is named N-[(4-chlorophenyl)carbamoyl]-2,6-difluorobenzamide. Common synonyms include Dimilin and Dimilin G1.

The product is provided as a solid. Store the standard in its sealed vial, protected from light and moisture, and follow the storage condition printed on the COA. The GHS classification uses the signal word “Warning”, so appropriate gloves, eye protection and ventilation are recommended.

As a reference sample of the parent drug substance, it is used for identification, assay and impurity-profiling work during analytical method development, validation (AMV) and routine QC. Typical end-use sectors are pharmaceutical manufacturing and academic and industrial research.

We offer Diflubenzuron in 10 mg, 25 mg, 50 mg and 100 mg packs with a batch-specific COA, and ship to customers worldwide.
