Pentafluoro-benzenesulfonic acid and S-benzyl-thiuronium-salt are two distinct chemical compounds with unique properties and applications. Pentafluoro-benzenesulfonic acid is an aromatic compound characterized by the presence of five fluorine atoms attached to a benzene ring, with a sulfonic acid group (-SO3H) attached to the ring. pentafluoro-benzenesulfonic acid ; S-benzyl-thiuronium-salt is known for its strong acidity and reactivity, making it useful in various chemical synthesis processes, particularly in the production of fluorinated compounds and pharmaceuticals. On the other hand, S-benzyl-thiuronium-salt is an organic compound that features a thiuronium cation (R-N=C=S) and a benzyl group (C6H5-CH2-). It is often used as a reagent in chemical analysis and synthesis, particularly in the detection and quantification of certain functional groups due to its ability to form colored complexes. Both compounds, while different in structure and use, contribute to the advancement of chemistry and related fields through their unique properties and reactivity.
The CAS Registry Mumber 632-45-1 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 6,3 and 2 respectively; the second part has 2 digits, 4 and 5 respectively. Calculate Digit Verification of CAS Registry Number 632-45: (5*6)+(4*3)+(3*2)+(2*4)+(1*5)=61 61 % 10 = 1 So 632-45-1 is a valid CAS Registry Number.
