It is a colorless liquid with a pungent odor and is highly reactive due to the presence of the phosphorus atom. (2-chloro-1,1,2-trifluoro-ethyl)-phosphane is primarily used as a reagent in the synthesis of various organophosphorus compounds, particularly in the production of pesticides and pharmaceuticals. It is also employed as a flame retardant and a precursor in the preparation of other phosphorus-containing compounds. Due to its reactivity and potential health hazards, it is essential to handle this chemical with proper safety measures and precautions.
The CAS Registry Mumber 421-54-5 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,2 and 1 respectively; the second part has 2 digits, 5 and 4 respectively. Calculate Digit Verification of CAS Registry Number 421-54: (5*4)+(4*2)+(3*1)+(2*5)+(1*4)=45 45 % 10 = 5 So 421-54-5 is a valid CAS Registry Number.
