75513-72-3 Usage
Purification Methods
Purify it by flash chromatography (at 40 kPa) on silica and eluting with EtOH/hexane (4:1). IR has (CHCl3) 1630cm-1. [Eene et al. Helv Chim Acta 63 2271 1980.] Itisa good magnesium selectophore compared with Na, K and Ca [Lanter et al. Anal Chem 52 2400 1980].
Check Digit Verification of cas no
The CAS Registry Mumber 75513-72-3 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 7,5,5,1 and 3 respectively; the second part has 2 digits, 7 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 75513-72:
(7*7)+(6*5)+(5*5)+(4*1)+(3*3)+(2*7)+(1*2)=133
133 % 10 = 3
So 75513-72-3 is a valid CAS Registry Number.

Lipophilic Di- and Triamides as Ionophores for Alkaline Earth Metal Cations
Erne, Daniel,Stojanec, Nadja,Ammann, Daniel,Hofstetter, Peter,Pretsch, Ernoe,Simon, Wilhelm
, p. 2271 - 2279 (2007/10/02)
Different electrically neutral lipophilic di- and triamides were prepared and their ion selectivity in membranes studied.In membranes the ionophore N,N'-diheptyl-N,N'-dimethyl-succinimide prefers Ca2+ over Mg2+ by a factor of 20 but
