21416-67-1, 4,4′-(Propane-1,2-diyl)bis(piperazine-2,6-dione) is a piperazines compound, ?involved in a variety of chemical synthesis. Rlated chemical reaction is continuously updated
At the beginning of each working day the capillary was flushed with NaOH 0.1M for 10min, 5min with Milli-Q water and 40min with the buffer in basic conditions and with MeOH for 5min, NaOH 1M for 25min, 5 min with Milli-Q water, 5min with HCl 0.1M and 30min with the buffer in acid conditions. In order to ensure the repeatability between injections, the capillary was flushed with NaOH 0.1M for 5min, 5min with the buffer and 2min with the BGE in basic or acid conditions. Buffer solutions were prepared by dissolving the appropriate amount of formic acid, acetic acid, ammonium bicarbonate or boric acid in Milli-Q water, adjusting the pH to the desired value (pH 2.5, 5.0, 7.0, or 9.0, respectively) with 0.1 or 1M NaOH before completing the volume with water to get the desired buffer concentration. Finally, BGEs were prepared by dissolving the appropriate amount of the chiral selectors in the buffer solution. Stock standard solutions of racemic captopril, econazole and clenbuterol were prepared by dissolving the appropriate amount of these drugs in MeOH and razoxane was prepared by dissolving the appropriate amount in Milli-Q water/25% DMF (v/v). These solutions were stored at 4C. All solutions (buffers and standards) were filtered through 0.45mum pore size nylon membrane filters before their injection in the CE system., 21416-67-1
The synthetic route of 21416-67-1 has been constantly updated, and we look forward to future research findings.
