Bis(trifluoroacetic acid)pentamethylene ester, also known as pentamethylene bis(trifluoroacetate), is a chemical compound with the molecular formula C7H6F6O4. It is a colorless liquid that is soluble in organic solvents and is commonly used as a reagent in organic synthesis. Bis(trifluoroacetic acid)pentamethylene ester is formed by the esterification of pentamethylene glycol with trifluoroacetic acid, resulting in a molecule that contains two trifluoroacetate groups attached to a central pentamethylene chain. Due to its unique structure and properties, it is often employed in the synthesis of various pharmaceuticals, agrochemicals, and other specialty chemicals, where it can act as a protecting group or a coupling agent.
The CAS Registry Mumber 453-44-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 4,5 and 3 respectively; the second part has 2 digits, 4 and 4 respectively. Calculate Digit Verification of CAS Registry Number 453-44: (5*4)+(4*5)+(3*3)+(2*4)+(1*4)=61 61 % 10 = 1 So 453-44-1 is a valid CAS Registry Number.
