Oxymetazoline Hydrochloride

We supply Oxymetazoline Hydrochloride that is made by the experts by using approved Pharmaceutical materials that are imported from the reliable vendors of the industry. The Oxymetazoline Hydrochloride, we formulate is demanded for its purity and accurate composition. Molecular Formula : C16H24N2O.HCl Molecular Weight : 296.84 SpecificationsGradesUSPBP/EPDescription A white to practically white, fine crystalline powder. Is hygroscopic.A white or almost white crystalline powder.SolubilitySoluble in water, in alcohol, practically insoluble in benzene, in chloroform and in ether.Freely soluble in water and in ethanol (96%).Melting PointShould melts at about 300oC with decomposition.-Identificationa) By IR
IR spectrum of sample recorded as Nujol mull should exhibit transmission minima (absorption maxima) at the same wavelengths to those in the spectrum obtained with the Oxymetazoline hydrochloride-working standard.a) By IR
IR spectrum of sample recorded as KBr should exhibit transmission minima (absorption maxima) at the same wavelengths to those in the spectrum obtained with the Oxymetazoline hydrochloride working standard.b) By UV (100 µg/ml in water)
Absorptivities at 279 nm, calculated on the dried basis, should not differ by more than 3.0 %.-c) By Chloride test
A curdy white precipitate should form, which settles in the test tube, indicating the presence of chlorides ions.c) By Chloride test
A curdy white precipitate should form, which settles in the test tube, indicating the presence of chlorides ions.pH (5 % w/v solution in water)Between 4.0 and 6.5-Appearance of solution (5 % w/v solution in water)-Solution S should be clear and not more intensely coloured than reference solution BY7Acidity/Alkalinity-Not more than 0.4 ml of 0.01 M of sodium hydroxide require to change the colour of the indicator to yellow.
