Dear AhmedEzatAlzawalaty;
(Hello once again.)
Independent of the Pharmacopoeias, I would all do it with UV/Vis Spectroscopy!
Disadvantage: You need a reference product.
Advantage: You are very specific and have at the same time the Identity.
(In case you use the Spectrum instead of “Single Wavelength” measurement.)
Disadvantage of Titration:
- Absolutely unspecific and very influenced from other Acids and Bases.
- You need an additional Identification (It’s required for Pharmacopoeias!).
Quintessence:
It depends very, very much on what your goals are.
I hope it may be of a little help to you.
Good Luck!
