Separation Method for Tizanidine Compatible with LC-MS
Tizanidine has numerous amine functional groups and can be a challenge for analysis with HPLC. The USP method uses Phosphate in the Mobile Phase which is not compatible with LC-MS. This Method however uses Formic Acid as the Mobile Phase additive and produces a sharp, symmetrical peak.
The USP system suitability for the tailing factor is not more than 1.6, and the Peak obtained has a value of 1.1.
