139-91-3 Usage
Uses
Used in Animal Feed Industry:
Furaltadone is used as an additive in the animal feed industry for its antibacterial properties, which help in maintaining the health and well-being of animals.
Used in Pharmaceutical Industry:
Furaltadone is used as a topical treatment in the pharmaceutical industry, specifically as the hydrochloride salt, for the treatment of ear disorders. Its antibacterial properties make it effective in combating infections and promoting ear health.
Used in Chemical Synthesis:
Furaltadone serves as an intermediate in the synthesis of AMOZ (A634600), which is another metabolite of Furaltadone Hydrochloride. This makes it an essential component in the development of new pharmaceutical compounds and treatments.

Manufacturing Process
11.17 g (0.78 mol) 3-(N-morpholinyl)-1,2-epoxypropane, BP 76.5°C to 78°C.
3.9 mm, prepared by Eisleb's method for 3-(1-piperidyl)-1,2-epoxypropane
(US Patent 1,790,042) is added dropwise in 12 minutes to 19.5 g (0.39 mol)
100% hydrazine hydrate, which has been warmed to 85% on the steam bath,
and is being mechanically stirred. The heat of the reaction maintains the
internal temperature at 90°C to 100°C without further external heating. The
reaction mixture is then warmed on the steam bath for an additional two
hours (90°C to 95°C). The excess hydrazine hydrate is removed in vacuo. The
residue of viscous 1-hydrazino-3-morpholinyl-2-propanol is not distilled, but is
mixed with 10.16 g (0.086 mol) diethyl carbonate and a solution of 0.3 g
sodium metal in 15 ml methyl alcohol. The mixture is refluxed about 2 hours
under a 15 cm Widmer column, the alcohol being removed leaving a thick,
green liquid residue, which is cooled and the precipitate which forms is
removed by filtration and washed well with ether. Yield 82%. MP 114°C to
116°C. Recrystallization from isopropanol gives purified 3-amino-5-(Nmorpholinyl)-methyl-2-oxazolidone, MP 120°C as the intermediate.
It is not necessary that the intermediate be separated from the reaction
medium in the preparation of the end product. Instead, the reaction mixture,
after cooling, is treated with 200 ml of water acidified with 42 ml 10% hydrochloric acid solution, and filtered. To the clear, light yellow filtrate is
added dropwise a solution of 9.8 g (0.07 mol) 5-nitro-2-furaldehyde in 100 ml
ethyl alcohol. An orange solution of the hydrochloride results. The free base is
precipitated as yellow plates by making the solution basic with saturated
sodium carbonate solution. 14 g of the compound is filtered off by suction,
washed with alcohol, and dried. The yield, MP 204°C to 205°C (dec.), is 53%
of theoretical based on 3-(N-morpholinyl)-1,2-epoxy-propane.
Recrystallization from 95% alcohol (75%recovery) raises the melting point to
206°C (dec.).
The hydrochloride salt is isolated quantitatively by suspending the base in
alcohol and adding sufficient aqueous concentrated HCl solution. The
precipitate becomes pale yellow, is filtered off, and recrystallized from 80%
alcohol. The MP range is about 223°C to 228°C (dec.).

Check Digit Verification of cas no
The CAS Registry Mumber 139-91-3 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 1,3 and 9 respectively; the second part has 2 digits, 9 and 1 respectively.
Calculate Digit Verification of CAS Registry Number 139-91:
(5*1)+(4*3)+(3*9)+(2*9)+(1*1)=63
63 % 10 = 3
So 139-91-3 is a valid CAS Registry Number.
