采用差示扫描量热法(DSC),根据DSC曲线利用纯度分析软件测定草酸艾司西酞普兰的纯度。对实验条件进行了优化,升温速率为4.0 K/min,称样量为2~3.2 mg。测得草酸艾司西酞普兰的纯度为99.17%,相对标准偏差为0.05%(n=6)。该法测定结果与非水滴定法测定结果(99.24%)基本一致。差示扫描量热法可用于测定草酸艾司西酞普兰纯度,方法操作简便、结果准确。
採用差示掃描量熱法(DSC),根據DSC麯線利用純度分析軟件測定草痠艾司西酞普蘭的純度。對實驗條件進行瞭優化,升溫速率為4.0 K/min,稱樣量為2~3.2 mg。測得草痠艾司西酞普蘭的純度為99.17%,相對標準偏差為0.05%(n=6)。該法測定結果與非水滴定法測定結果(99.24%)基本一緻。差示掃描量熱法可用于測定草痠艾司西酞普蘭純度,方法操作簡便、結果準確。

The differential scanning calorimetry (DSC) technique was used to determine the purity of escitalopram oxalate, according to the DSC curve and by using the purity analysis software. The experimental conditions were optimized, the heating rate was 4.0 K/min and the sample mass was 2-3.2 mg. The purity result determined by DSC method was 99.17%, RSD was 0.05%(n=6). The result was consistent with the result (99.24%) determined by the non-aquseous trirtation method. The DSC method is accurate and simple for the determination of escitalopram oxalate purity.
