Abstract

The invention relates to a medicine analyzing method and particularly relates to a method for measuring impurities in tamibarotene and a preparation thereof by using high performance liquid chromatography. Octadecyl silane bonding silica gel is used as a filling agent, a phosphoric acid buffer solution with a volume ratio of water to phosphoric acid being 2000:1-2000:5 is used as a mobile phase A, acetonitrile is used as a mobile phase B, and a gradient elution process is adopted to establish a sensitive, exclusive and comprehensive tamibarotene impurity detecting and analyzing method. The method can be adopted to effectively detect changes of impurities in production and storage processes of the tamibarotene, and has important practical significance to medicine quality control.

Description

technical field [0001] The invention relates to a drug analysis method, in particular to a method for determining content and impurities in tamibarotene and its preparations by high performance liquid chromatography. Background technique [0002] Drug impurity research is one of the main guarantees for controlling drug quality and safety. Because a drug has to go through a relatively complicated and lengthy process from the synthesis of raw materials to the preparation of related preparations, and then through storage, transportation, and use, during which each process may produce related impurities. Into starting materials, reagents, intermediates, by-products and isomers, etc.; special impurities such as degradation products, polymers or crystal transformations may be produced during storage and transportation. Impurities in pharmaceuticals generally refer to process impurities or degradation products produced during the production, storage and transportation of pharmaceu...
