(6,6'-Dimethoxy-2,2'-biphenyldiyl)bis[bis(3,4,5-trimethoxyphenyl)phosphine](CAS: 256390-47-3)

This compound has a crystalline form with a molecular weight of approximately 1016.46 g/mol. It is poorly soluble in water but soluble in organic solvents like acetone and ethyl acetate. Chemically, it is highly reactive due to the presence of multiple functional groups.

This compound is typically synthesized via a multistep process involving the coupling of 2,2'-biphenyldiyl dibromide with 3,4,5-trimethoxyphenyl phosphine. Common catalysts include triphenylphosphine and triethylamine. The overall yield is around 70% with good selectivity.

This compound is used in the pharmaceutical industry for its potential in drug synthesis, as well as in the semiconductor industry for its use as a dopant. It also has applications in sensors due to its reactivity and stability.

Proper personal protective equipment (PPE) including gloves, goggles, and a lab coat should be worn. This compound should be handled in a fume hood to minimize exposure. In case of a spill, it should be cleaned up using appropriate absorbents and disposed of according to local regulations. Safety Data Sheets (SDS) should always be consulted for detailed handling instructions.
