CAS 704-38-1

Bis(2-thienyl) ketone

Description:

Bis(2-thienyl) ketone, with the CAS number 704-38-1, is an organic compound characterized by its structure, which features two thienyl groups (derived from thiophene) attached to a carbonyl group. This compound typically appears as a yellow to brown solid and is known for its aromatic properties due to the presence of the thienyl rings. It exhibits moderate solubility in organic solvents, such as ethanol and dichloromethane, but is generally insoluble in water. Bis(2-thienyl) ketone is of interest in various fields, including organic synthesis and materials science, due to its potential applications in the development of organic semiconductors and as a building block for more complex molecules. Its reactivity is influenced by the electron-rich nature of the thienyl groups, allowing for various chemical transformations. Additionally, it may exhibit interesting photophysical properties, making it a candidate for studies in photochemistry and photophysics. Safety data should be consulted for handling and storage, as with any chemical substance.

Di-2-thienylmethanone

CAS: 704-38-1

Di-2-thienylmethanone is a pyrazole with an activation energy of about 10.5 kcal/mol. It has been found to be toxic and can cause cell lysis. This molecule has been used in the synthesis of a number of drugs, including thiopental, a barbiturate that is used as an anaesthetic. Di-2-thienylmethanone is also the precursor for the synthesis of fluoroquinolones, which are potent antibacterial agents. The Friedel-Crafts reaction is one way this molecule is synthesized, and it involves the addition of an alkyl halide to an unsaturated double bond. This reaction is named after Charles Friedel and James Crafts who first discovered it in 1877.
