Identification A.The retention time of HPLC
B. IR |
Examine the chromatograms obtained in the assay: the retention time to the principal peak in the chromatograms obtained with the rest solution is similar in retention time to the principal peak in the chromatograms obtained with reference solution The IR spectrum of the sample is same as the reference standard. |
