To determine the purity of (1S, 3aR, 6aS) -octahydrocyclopento [c] pyrrole-1 -carboxylic acid ethyl ester amide (1:1), we can use various modern ingenious methods.
One is high performance liquid chromatography (HPLC). This technique uses a high pressure pump to drive the mobile phase, carrying the sample through a column filled with a specific stationary phase. Due to the different interactions between the components in the sample and the stationary phase, their migration rates in the column are different, and then flow out of the column one after another, which is responded by the detector and converted into an electrical signal, which is presented as a chromatographic peak. According to the peak area or peak height, the purity of the target can be accurately determined. < Br >
Second, gas chromatography (GC) is also a good choice. It is suitable for volatile samples. After the sample is gasified in the gasification chamber, it enters the chromatographic column with the carrier gas, and is detected by the detector after separation. The purity can be determined by the parameters of the peak.
Furthermore, nuclear magnetic resonance spectroscopy (NMR) is also quite powerful. Nuclei in different chemical environments have different resonance frequencies in the magnetic field. By analyzing the position and integrated area of the peaks in the spectrum, information about the molecular structure and purity of the sample can be obtained.
In addition, melting point determination is also helpful. The purified product has a specific melting point and a narrow melting range. If the sample contains impurities, the melting point is often reduced and the melting range is also widened. However, this is only a preliminary estimate and needs to be used in combination with other methods.
In actual operation, the constant parallel number method is confirmed to obtain accurate purity results.
