摘 要:建立丙硫唑的高效液相色譜分析方法。樣品用冰醋酸溶解,采用 Agilent TC-C18 反相柱為色譜柱,v(甲醇) ∶ v(水)=70 ∶ 30為流動(dòng)相,PDA檢測器在295 nm 對丙硫唑進(jìn)行高效液相色譜分離和測定。方法在32~320 μg·mL-1的濃度范圍內線(xiàn)性關(guān)系良好,其線(xiàn)性回歸方程:y=23 584x-517.84,相關(guān)系數r=0.999 9,變異系數為 0.2%,回收率為 99.0%~100.4%。該方法簡(jiǎn)單可靠,精確度和準確度符合定量分析要求,可用于丙硫唑定量分析。 |

Abstract:To establish a high performance liquid chromatography method for methyl 5-(propylthio)-1H-benzo[d]imidazol-2-ylcarbamate, the samples in glacial acetic acid was separated using reverse phase column Agilent TC-C18 as chromatographic column while mobile phase was used as a methanol to water volume ratio of 70:30. PDA detector was set to separate and read the signal of compound at 295 nm.This method detected compound's signal nicely and regressed to linear model between 32~320 μg·mL-1 of concentration. The regressed linear function was y=23 584x-517.84 and the regression coefficiency r was of 0.999 9, coefficient of variant is of 0.2%, recovery percentage was of 99.0% to 100.4%.The method reported here was a simple, stable and accurate one that meet the requirments for quantitative analysis of methyl 5-(propylthio)-1H-benzo[d]imidazol-2-ylcarbamate. |
