    Abstract: The purpose of this research study is to develop a novel, simple, precise, accurate and economical method for determination of Apixaban API isomers. Apixaban API has three isomer as ortho, meta and para. In reverse phase and normal phase chromatography it was very difficult to separate these isomer; hence new chiral technique was adopted. This chro... Show More
