Benzil, 99%

About Benzil, 99%

Benzil is a bioactive small molecule in Synthesis grade carrying the CAS registry number 134-81-6 with a typical assay of 99%. With the molecular formula C14H10O2, it has a molar mass of 210.23 g/mol. Systematically, it is named 1,2-diphenylethane-1,2-dione. Alternative names: Dibenzoyl and Diphenylethanedione.

In its supplied form it is faint yellow to dark yellow powder or crystals or granules or chunks. Literature values give a melting point of 94-95 °C. Keep the container tightly sealed and store it in a cool, dry area. The GHS classification uses the signal word “Warning”, so appropriate gloves, eye protection and ventilation are recommended.

Key uses span cell signalling research, pharmacological screening, target validation and polymer and resin production. Typical end-use sectors are academic and industrial research and diagnostics and biotechnology.

We offer Benzil in 250 g, 500 g, 1 kg and 4 x 25 kg packs with a batch-specific COA, and ship to customers worldwide.
