Interpretation:
The prominent peak observed around 3430 cm⁻¹ corresponds to the stretching vibration of
hydroxyl (OH) groups, indicating the presence of primary and secondary hydroxyl groups in
chitosan hydrochloride. This peak signifies the potential for hydrogen bonding and
intermolecular interactions, which are crucial for its physicochemical properties and various
applications.
Another important feature is the peak observed around 1400-1500 cm⁻¹, corresponding to the
bending vibration of the amine groups (NH2) present in chitosan hydrochloride. This peak
confirms the presence of amino functionalities and serves as an indicator of the polymer's
overall composition and structure.
Furthermore, the FTIR spectrum of chitosan hydrochloride may exhibit additional peaks related
to other functional groups, such as C-O stretching vibrations in the region of 1000-1200 cm⁻¹,
which are associated with the glycosidic linkages in the chitosan backbone.
Characterization Results summary
The evaluation tests of chitosan hydrochloride revealed promising results regarding its
suitability for pharmaceutical applications. The results indicated the consistent quality and
purity of the chitosan hydrochloride samples. The pH measurements demonstrated an
appropriate acidic range, facilitating its compatibility with various drug substances and
formulations. Furthermore, solubility tests demonstrated its excellent solubility characteristics,
which is crucial for effective drug delivery systems. The viscosity analysis reveal ed a suitable
range for the intended pharmaceutical applications, allowing the formulation of various dosage
forms such as gels and solutions.
