With the rapid development and complex challenges of chemical substances, new drug synthesis pathways are usually the most effective.1121-22-8,trans-Cyclohexane-1,2-diamine,as a common compound, the synthetic route is as follows.
A 10 mL sample solution containing 1.0 mg/L of trans-cyclohexane-1,2-diamine was placed in a centrifuge tube with narrow neck (~4 mm i.d.), which was specially designed for ease of removing the supernatant phase. A mixture of 1 mL disperser solvent and 300 muL extracting solvent with 2 mmol L-1 of chiral selector was rapidly injected into the sample solution using a 5.0 mL syringe, and mixed by vortex mixer at 500 rpm stirring rate for 20 min, so that a cloudy solution was formed. The cloudy solution was centrifuged for 5 min at 3500 rpm, and the extraction product (supernatant phase) was collected in the neck of the tube. Finally, this supernatant phase was derivatized and injected into the HPLC. All of the experiments were carried out in triplicate and the average of the result was reported.
1121-22-8, As the paragraph descriping shows that 1121-22-8 is playing an increasingly important role.
