CAS 134-81-6

Benzil

Description:

Benzil, with the CAS number 134-81-6, is an organic compound characterized by its structure as a diketone, specifically a symmetrical molecule featuring two carbonyl (C=O) groups flanked by two phenyl (C6H5) groups. It appears as a white to pale yellow crystalline solid and is known for its relatively low solubility in water but good solubility in organic solvents such as ethanol and acetone. Benzil is primarily used in organic synthesis and as a photoinitiator in polymerization processes. It exhibits interesting photochemical properties, undergoing a rearrangement reaction known as the benzilic acid rearrangement when treated with a base, which can lead to the formation of benzilic acid. Additionally, benzil has applications in the field of medicinal chemistry and materials science. Its melting point and boiling point are indicative of its stability and reactivity, making it a valuable compound in various chemical applications. Safety precautions should be observed when handling benzil, as it can cause irritation upon contact with skin or eyes.

Benzil is a fluorescent probe that is used to measure the activity of polymerase chain reactions (PCRs). It has been shown to inhibit the growth of amoebae, and has significant cytotoxicity. Benzil also exhibits in vitro antifungal activity against Candida albicans, and is used for the diagnosis of bone cancer. The mechanism of benzil's action is not well understood. However, it may be due to its ability to bind with nitrogen atoms on nucleic acids and block their synthesis. Benzil also has biological properties and can be used for skin cancer diagnosis.
