1. Data Collection: Collect chromatographic conditions and corresponding separation performance data related to the detection of trifloxystrobin intermediate (E) methyl α-(methylimino)-2-(o-tolyl)acetate from experimental records. The collected data covers chromatographic parameters including chromatographic column, mobile phase, detection wavelength, flow rate and column temperature, as well as separation performance indicators such as resolution, tailing factor and analysis cycle.
2. Data Processing:
1) Compare the effects of chromatographic columns of different models and specifications on the separation of the intermediate and its impurities, and record data such as resolution and retention time of the target peak and impurity peaks under each chromatographic column;
2) Explore the effect of different volume ratio combinations of acetonitrile and water on separation performance, analyze the influence of mobile phase composition on the resolution and peak shape of the target peak and impurity peaks, and count relevant data under each ratio;
3) Adjust parameters such as detection wavelength, flow rate and column temperature, observe the changes of response values, resolution and analysis cycle of the target compound and its impurities, and collect experimental data corresponding to different parameter combinations;
4) Perform comprehensive analysis on the data collected from the above aspects, calculate indicators including resolution, tailing factor and analysis cycle under different chromatographic conditions, and select the chromatographic condition combination with resolution ≥ 1.5, tailing factor ≤ 1.2, short analysis cycle and relative standard deviation (RSD) of repeatability ≤ 2% as the optimal chromatographic conditions.
3. Data Application: The determined optimal chromatographic conditions can be applied to the quality detection of trifloxystrobin intermediate (E) methyl α-(methylimino)-2-(o-tolyl)acetate, ensuring the accuracy and reliability of test results. They can also provide references for the development of chromatographic analysis methods for this intermediate and compounds with similar structures.
