Identification by

a. IR

The infrared absorption spectrum of finely ground sample in potassium bromide dispersion compressed into a pellet, exhibits maxima only at the same wave lengths as that of a similar preparation of the corresponding Dextromethorphan HBr WS

b. UV absorption

Absorbtivity at 278nm of sample (100μg/ml(on anhydrous basis)solution in 0.1N hydrochloric acid) do not differ from a similar preparation of Dextromethorphan Hydrobromide WS by more than 3.0%

c. With silver Nitrate TS

A yellowish wihte precipitate formed when 5 drops of 2N nitric acid and 2ml of silver nitrate TS are added to 5ml of sample solution.

Melting point

Melts at about 126°C with decomposition.

Specific optical rotation at 25°

The specific rotation of the sample at 325nm do (on anhydrous basis) not differ from a similar preparation of (C=1,8 in water) Dextromethorphan hydrobromic WS, by more than 1.0%

Ph (1 in 100)

Between 5.20 and 6.50

Water by KF

Between 3.5and 5.5% w/w

Residue on ignition

Not more than 0.1% w/w

Limit of N,N-dimethylaniline

Not more than 0.001%

Limit of phenolic compounds

No blue-green colour develops

Assay (on anhydrous basis)

Not less than 98.0% and

Not less than 102.0% w/w
