Propanoyl chloride, 2,3,3,3-tetrafluoro-, also known as 2,3,3,3-tetrafluoropropanoyl chloride or 2,3,3,3-tetrafluoropropionyl chloride, is a chemical compound with the molecular formula C3H2ClF4O. It is a colorless liquid with a pungent odor and is used as a reagent in organic synthesis, particularly in the preparation of pharmaceuticals and agrochemicals. Propanoyl chloride, 2,3,3,3-tetrafluoro- is characterized by its high reactivity due to the presence of the acyl chloride group, which can readily undergo nucleophilic substitution reactions. It is also known for its stability and resistance to hydrolysis, making it a valuable intermediate in the synthesis of various fluorinated compounds. However, due to its corrosive nature and potential health hazards, it requires careful handling and is typically used in well-ventilated areas with appropriate safety measures.
The CAS Registry Mumber 1186-54-5 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 1,1,8 and 6 respectively; the second part has 2 digits, 5 and 4 respectively. Calculate Digit Verification of CAS Registry Number 1186-54: (6*1)+(5*1)+(4*8)+(3*6)+(2*5)+(1*4)=75 75 % 10 = 5 So 1186-54-5 is a valid CAS Registry Number.
