2-Mercapto-hexafluoropropan-2-ol, also known as 2-mercapto-1,1,1,3,3,3-hexafluoropropan-2-ol or HFIP-SH, is a colorless liquid with a molecular formula of C3H2F6OS. It is a derivative of hexafluoroisopropanol (HFIP), where one of the hydroxyl groups is replaced by a thiol group. This chemical is characterized by its strong reactivity due to the presence of the thiol functional group, which can readily form disulfide bonds with other thiol-containing molecules. It is used in various applications, including the synthesis of pharmaceuticals, as a reagent in organic chemistry, and in the preparation of specialty polymers. Due to its reactivity, it is typically handled with care in a controlled environment.
The CAS Registry Mumber 2056-81-7 includes 7 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 4 digits, 2,0,5 and 6 respectively; the second part has 2 digits, 8 and 1 respectively. Calculate Digit Verification of CAS Registry Number 2056-81: (6*2)+(5*0)+(4*5)+(3*6)+(2*8)+(1*1)=67 67 % 10 = 7 So 2056-81-7 is a valid CAS Registry Number.
