| Abstract: | Procaterol hydrochloride(1) and its tablets and its related substances were determined by HPLC.The RSD of the replicate determinations and the average recovery were not more than 0.5%.Four peaks of impurities could be separated from 1.1 tablets were also determined by the double wave length first order derivative spectrophotometry to eliminate the interference of excipients.The RSD was less than 0.72%,while the average recovery of 1 was 99.50%. |
