Changes in Test Methods for Internationalization in the Japanese Pharmacopoeia (Part 3): Establishment of a Quantitative Method for Sodium Cromoglicate and Trihexyphenidyl Hydrochloride Using HPLC Analysis

In this study, we synthesized the related impurities of sodium cromoglicate and trihexyphenidyl hydrochloride listed in the EP and determined their purities using quantitative NMR. The separation conditions of these compounds were examined using HPLC and simultaneous analyses were performed.PMID:36858562 | DOI:10.1248/yakushi.22-00188
