Purification Methods
Purify it by stirring 16g of reagent for a few minutes with 100mL absolute EtOH and filter by suction as rapidly as possible through coarse filter paper. Sufficient EtOH is added to the filtrate, to make up for the loss of EtOH and to redissolve any solid that separates. Water (15mL) is added to the filtrate, and the solution is evaporated with a stream of N2 until reduced to half its volume. Cool for a few minutes and filter off the yellow crystals, dry them under a stream of N2, then in a vacuum at room temperature for 6-8hours. These conditions are important for obtaining the dihydrate. A vacuum to several mm of Hg or much lower pressure for several days produces the anhydrous complex. The degree of hydration can be established by determining the loss in weight of 100g of sample after heating for 4hours at 100o and <20mmHg. The theoretical loss in weight for 2H2O is 12.5%. The material sublimes at 200o/2mm. It is soluble in heptane, MeOH, EtOH or *C6H6 at 30o. [Charles Inorg Synth VI 164 1960, Fernelius & Biswas Inorg Synth V 105 1957, Beilstein 3 II 3122.]
Check Digit Verification of cas no
The CAS Registry Mumber 14024-58-9 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 1,4,0,2 and 4 respectively; the second part has 2 digits, 5 and 8 respectively.
Calculate Digit Verification of CAS Registry Number 14024-58:
(7*1)+(6*4)+(5*0)+(4*2)+(3*4)+(2*5)+(1*8)=69
69 % 10 = 9
So 14024-58-9 is a valid CAS Registry Number.

The ternary complexes with stoichiometry [M(imda)(bipy)]·6H2O (M = Cu) and [M(imda)(bipy)(H2O)]·4H2O (M = Ni, Co and Mn) where H2imda = iminodiacetic acid and bipy = 2,2′-bipyridine, are prepared and characterized to exploit as novel antimicrobial agents and SOD mimics. The chemical structures were elucidated by IR, FAB-Mass, 1H, 13C NMR, EPR and spectral techniques. Single crystal X-ray and spectral studies of the complexes (1) and (2) have confirmed a square pyramidal geometry around Cu(II) ion while a saturated six coordinate (distorted octahedral) geometry around the Ni(II), Co(II) and Mn(II) ions due to the additional coordination from water. A supramolecular network is formed by extensive H-bonding in complex (1). The supramolecular assembly in complex (1) is additionally consolidated via the existence of unusual cyclic hexameric water clusters. The antimicrobial activities for the present complexes have been examined against Escherichia coli (K-12), Bacillus subtilis (MTC-121), Staphylococcus aureus (IOASA-22), Salmonella typhymurium (MTCC-98), Candida albicans, Aspergillus fumigatus and Penicillium marneffei. The superoxide dismutase (SOD) activity of the Cu(II) complex (1) is also assessed employing nitrobluetetrazolium (NBT) assay.
