Phosphinic chloride, ethenylphenyl-, also known as (2-ethenylphenyl)phosphinous chloride or styrene phosphinic chloride, is an organophosphorus compound with the chemical formula C8H9Cl2P. It is a colorless to pale yellow liquid with a pungent odor and is soluble in organic solvents. This chemical is primarily used as a reagent in the synthesis of various phosphorus-containing compounds, such as phosphonates, phosphinates, and phosphine oxides. It is also employed in the production of flame retardants, agrochemicals, and pharmaceuticals. Due to its reactivity, it is essential to handle Phosphinic chloride, ethenylphenyl- with care, using appropriate safety measures and protective equipment.
The CAS Registry Mumber 5290-57-3 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 5,2,9 and 0 respectively; the second part has 2 digits, 5 and 7 respectively. Calculate Digit Verification of CAS Registry Number 5290-57: (6*5)+(5*2)+(4*9)+(3*0)+(2*5)+(1*7)=93 93 % 10 = 3 So 5290-57-3 is a valid CAS Registry Number.
