Purification Methods
Purify the dye by chromatography on neutral alumina using dry *C6H6 with 1% of dry MeOH. The major component, which gave a stationary band, is cut out and eluted with EtOH or MeOH. [H.gfeldt & Bigeleisen J Am Chem Soc 82 15 1960.] It crystallises from pet ether, EtOH or aqueous EtOH, and has max at 420nm ( 28,000) (aqueous EtOH) and 540nm (aqueous EtOH/H2SO4) [Badger et al. J Chem Soc 1888 1954, Beilstein 16 H 314, 16 III 343, 16 IV 457.]
Check Digit Verification of cas no
The CAS Registry Mumber 101-75-7 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,0 and 1 respectively; the second part has 2 digits, 7 and 5 respectively.
Calculate Digit Verification of CAS Registry Number 101-75:
(5*1)+(4*0)+(3*1)+(2*7)+(1*5)=27
27 % 10 = 7
So 101-75-7 is a valid CAS Registry Number.

A process for producing amino or amido substituted aromatic azo or hydrazo compounds, or aminoaromatic amines, or aminoaromatic amides, or mixtures thereof, comprises the steps of: (a) bringing into reactive contact in a suitable solvent system a nucleophilic compound selected from the group of aniline, substituted aniline derivatives, aliphatic amines, substituted aliphatic amine derivatives, amides and substituted amide derivatives with an azo containing compound; and (b) reacting the nucleophilic compound and the azo containing compound in a confined zone at a suitable time, pressure and temperature.

A series of push-pull type 4-phenylaminoazobenzene derivatives bearing an electron-withdrawing 4'-substituent were probed by electronic spectra in solution. The visible absorption maxima of these azobenzenes were correlated with the solvent parameters through the McRae theory as well as the solvent donor numbers. While the absorption spectra of these neutral species were solvent-dependent, those of protonated species were almost solvent independent. On the other hand, the absorption maxima and the rates of thermal cis-to-trans isomerization in a given solvent were correlated with Hammett constants. These results are discussed with the help of semi- empirical molecular-orbital calculations and compared with previously published data on related compounds.
