52960-14-2 Usage
General Description
1-Pentanesulfonamide is an organic compound with the chemical formula C5H11NO2S. It is a sulfonamide derivative of pentane and it is often used in organic synthesis as a reagent for the formation of amides and in the manufacture of pharmaceuticals. 1-Pentanesulfonamide is a clear, colorless to light yellow liquid with a slightly ammoniacal odor. It is soluble in water and organic solvents and is commonly used as a polar aprotic solvent in various chemical reactions and processes. Additionally, it is used as a corrosion inhibitor and as a stabilizer for chlorine dioxide in water treatment.
Check Digit Verification of cas no
The CAS Registry Mumber 52960-14-2 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 5,2,9,6 and 0 respectively; the second part has 2 digits, 1 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 52960-14:
(7*5)+(6*2)+(5*9)+(4*6)+(3*0)+(2*1)+(1*4)=122
122 % 10 = 2
So 52960-14-2 is a valid CAS Registry Number.

Intramolecular asymmetric amidations of sulfonamides and sulfamates catalyzed by chiral dirhodium(II) complexes
Fruit, Corinne,Mueller, Paul
, p. 1607 - 1615 (2007/10/03)
Enantioselective intramolecular amidation of aliphatic sulfonamides was achieved for the first time by means of chiral carboxylatodirhodium(II) catalysts in conjunction with PhI(OAc)2 and MgO in high yields and with enantioselectivities of up to 66% (Scheme 3, Table 1). The best results were obtained with [Rh2{(S)-nttI)4] and [Rh 2{(R)-ntv)4] as catalysts ((S)-nttl = (αS)-α- (tert-butyl)-1,3-dioxo-2H-benz[de]isoquinoline-2-acetato, (R)-nto = (αR)-α-isopropyl-1,3-dioxo-2H-benz[de] isoquinoline-2-acetato). In addition, these carboxylatodirhodium(II) catalysts were also efficient in intramolecular amidations of aliphatic sulfamates esters, although the enantioselectivity of these latter reactions was significantly lower (Scheme 4, Table 3).
