Dianhydride analysis method |
abstract |
The present invention relates to a dianhydride analysis method, which can reliably analyze a dianhydride having high reactivity and low solubility. In addition, the present invention can analyze the structure of impurities by separating the impurities on the basis of having a similar retention time in HPLC analysis, and can analyze the purity of the dianhydride with or without chromophores. |
