Manufacturing Process
48.5 parts of ethyl 4'-chlorophenoxyisobutyrate are dissolved in 200 parts by
volume of dry toluene in the presence of 262 parts of 4-hydroxy-N,Ndimethylbutyramide and 2 parts of aluminum isopropylate. The solution is
heated for 8 hours, while collecting the toluene-ethanol azeotrope, in an
apparatus provided with a distillation column at a controllable rate of reflux.
After this it is filtered ,the solvent is evaporated in vacuo and the residue is
distilled. An almost colorless, slightly yellow oil is obtained, the purity of which
by chromatographic examination in the gaseous phase is of the order of
99.5%. Its boiling point is 175°C under 0.1 torr.48.5 parts of ethyl 4'-chlorophenoxyisobutyrate are dissolved in 200 parts by

ambient temperature in petrol ether, ethyl ether or isopropyl ether, and this
solution is cooled at about -50°C while stirring. After drying over sulfuric acid
under vacuum, white needles of very great purity are thus obtained.

Check Digit Verification of cas no
The CAS Registry Mumber 26717-47-5 includes 8 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 5 digits, 2,6,7,1 and 7 respectively; the second part has 2 digits, 4 and 7 respectively.
Calculate Digit Verification of CAS Registry Number 26717-47:
(7*2)+(6*6)+(5*7)+(4*1)+(3*7)+(2*4)+(1*7)=125
125 % 10 = 5
So 26717-47-5 is a valid CAS Registry Number.

Process for the production of dry pharmaceutical forms and the thus obtained pharmaceutical compositions
-
, (2008/06/13)
A process for the production of a solid dispersion of at least one therapeutic agent in a hydrophilic carrier having enhanced solubility in an aqueous media comprising dissolving at least one therapeutic agent in a volatile organic solvent containing a very hydrophilic polymer and evaporating the solvent to dryness; to form a co-precipitate of therapeutic agent and hydrophilic polymer. This invention relates to the resulting products and to their therapeutic method of use.
