532-80-9 Usage

Check Digit Verification of cas no

The CAS Registry Mumber 532-80-9 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,3 and 2 respectively; the second part has 2 digits, 8 and 0 respectively.
Calculate Digit Verification of CAS Registry Number 532-80:
(5*5)+(4*3)+(3*2)+(2*8)+(1*0)=59
59 % 10 = 9
So 532-80-9 is a valid CAS Registry Number.

Direct separation and determination of synephrine enantiomers by high- performance liquid chromatography with electrochemical detection

Kusu,Matsumoto,Takamura

, p. 1158 - 1161 (1995)

High-performance liquid chromatography (HPLC) with electrochemical detection using a chiral ligand-exchange column (Sumichiral OA-5000) and a mobile aqueous phase containing 1 mM copper(II) acetate and 20 mM ammonium acetate (pH 6.4) was applied to the di

Facile one-pot preparation of chiral monoliths with a well-defined framework based on the thiol-ene click reaction for capillary liquid chromatography

Zhang, Peng,Wang, Jiannan,Yang, Haiguan,Su, Linjing,Xiong, Yuhao,Ye, Fanggui

, p. 24835 - 24842 (2016/03/22)

A novel chiral cyclodextrin (CD) monolith was easily prepared via a one-pot process based on the thiol-ene click reaction of allyl-β-CD with pentaerythritol tetra-(3-mercaptopropionate) in a fused-silica capillary. The effects of both the composition of prepolymerization solution and reaction temperature on the morphology, permeability, and selectivity of the β-CD chiral monolith were investigated in detail. The conditions were optimized to fabricate a homogeneous and permeable chiral monolith. In this study, the β-CD monolith was used as the stationary phase of capillary liquid chromatography for the chiral separation of several pharmaceutical enantiomers including flavanone, flurbiprofen, naproxen, synephrine, isoprenaline sulfate, ketoprofen, and atropine sulfate monohydrate. Compared to the previously reported two-step method, this one-pot method for the preparation of a β-CD chiral monolith is simple and time-saving. Moreover, good resolutions were obtained for chiral isomers in a shorter analysis time compared to that reported in the literatures. These results indicate that the thiol-ene click chemistry provides a simple and robust method for the preparation of a chiral β-CD monolith.

Chiral separation of drug enantiomers by capillary electrophoresis using succinyl-β-cyclodextrin

Schmid,Wirnsberger,Guebitz

, p. 852 - 854 (2007/10/03)

A capillary electrophoretic method for the enantiomeric separation of 11 drugs was developed using an uncoated fused-silica capillary and succinyl β-cyclodextrin as a chiral additive. The effect of the pH of the background electrolyte on selectivity and resolution was studied in the range pH 3.3-9.3. Best results were obtained in a neutral medium. Generally, the presence of a hydroxy group at the chiral C-atom of the analyte seems to be essential because similar compounds without a hydroxy group at the chiral centre did not show chiral resolution. In addition to the enantioselective inclusion into the chiral cavity, hydrogen bondings and formation of ion pairs between the negatively charged selector and cationic analytes can be assumed as mechanisms.
