HEPES CAS 7365-45-9 biological biological; Zotchingira zochitira, zotchingira zisanakhale zosakanizidwa ndi zotchingira zosakanizidwa polekanitsa ndi kusanthula zida zanyukiliya za RNA; Kwa RNA ndi t4rna.

2-Amino-5-nitropyridine CAS 4214-76-0 imachokera ku nitration ya 2-aminopyridine. Pa kutentha kwa 50 °C, 2-aminopyridine inawonjezeredwa ku asidi sulfuric woyikirapo, kenako fuming nitric acid anawonjezedwa dropwise, ndi kutentha sikunapitirire 50 °C. Yalirani pa 45 ° C kwa 2h, ndikuyambitsa kutentha kwa 4h. Njira yothetsera idatsanuliridwa mu ayezi wophwanyidwa, ndipo pH idasinthidwa kukhala 6 powonjezera madzi ammonia pansi pa 5 ° C, ndipo makhiristo adawomberedwa. Sefa ndi kuyanika. Recrystallization ndi madzi kuti mupeze mapulateleti otumbululuka achikasu, perekani 75%
