Triphenylphosphine (TPP) is a white, crystalline phosphorus compound widely used as a ligand in homogeneous catalysis, a reducing agent in organic synthesis, and a reagent in Wittig reactions. It appears as off-white flakes with a faint odor, highly soluble in organic solvents but insoluble in water. Triphenylphosphine has a CAS number of 603-35-0, a molecular formula of (C6H5)3P, and a molecular weight of 262.29 g/mol. It is classified as a dangerous substance (Signal Word: Danger) and must be stored at ambient conditions in a well-ventilated area, protected from moisture and light. Molekula supplies Triphenylphosphine from research to bulk quantities with full documentation and ISO 9001:2015 traceability.
