38533-41-4 Usage

Purification Methods

Purify the salt by dissolving it in the minimum volume of hot water (60o) and adding EtOH, with stirring, then leave at 0o for 1hour. The crystals are filtered off and recrystallised from H2O until free of Cl and SO2-ions. Dry it in a vacuum over P2O5 at room temperature. It is a specific substrate for arylsulfatases which hydrolyse it to p-acetylphenol [max 327nm ( 21700 M-1cm-1)] [Milsom et al. Biochem J 128 331 1972].

Check Digit Verification of cas no

The CAS Registry Mumber 38533-41-4 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 3,8,5,3 and 3 respectively; the second part has 2 digits, 4 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 38533-41:
(7*3)+(6*8)+(5*5)+(4*3)+(3*3)+(2*4)+(1*1)=124
124 % 10 = 4
So 38533-41-4 is a valid CAS Registry Number.

34S Isotope Effect on Sulfate Ester Hydrolysis: Mechanistic Implications

Burlingham, Benjamin T.,Pratt, Lisa M.,Davidson, Ernest R.,Shiner Jr., Vernon J.,Fong, Jon,Widlanski, Theodore S.

, p. 13036 - 13037 (2003)

In this communication, we report the first determination of 34S kinetic isotope effects (KIEs) for the hydrolysis of sulfate monoesters. The method involves the conversion of the inorganic sulfate, acquired at partial extent of reaction, to SO2, followed by isotope ratio determination by mass spectrometry. The KIEs determined for p-nitrophenyl sulfate and p-acetylphenyl sulfate are 1.0154 (±0.0002) and 1.0172 (±0.0003), respectively. These results, together with previous peripheral 18O KIE values, are inconsistent with an associative mechanism. The isotope effect method we report should also prove useful for studying the mechanism of other sulfuryl group transfers, including sulfatase and sulfotransferase reactions, as well as sulfate hydrolyses under other conditions.
