I-2-Amino-3-benzyloxypyridine CAS 24016-03-3 i-Heterocycle series; Idayi ephakathi; Izixhobo ze-Organic;
I-2-Amino-5-fluorobenzoic acid CAS 446-08-2 ibaluleke kakhulu kwi-precursor yokwenziwa kwamachiza, i-herbicides, izilawuli zokukhula kwezityalo kunye ne-fungicides yohlobo lwe-quinoline.
I-2-Chloro-4-nitrobenzoic acid CAS 99-60-5 Inaliti emhlophe okanye ephuzi emthubi okanye i-crystal powder. Indawo yokunyibilikisa i-142-143 ° C (139-141 ° C). Inyibilika emanzini ashushu, utywala kunye nebenzene eshushu.
I-4-Amino-3-nitrobenzoic acid CAS 1588-83-6 esetyenziswa njengedayi ephakathi
I-2-Amino-5-nitropyridine CAS 4214-76-0 ivela kwi-nitration ye-2-aminopyridine. Kwiqondo lobushushu le-50 °C, i-2-aminopyridine yongezwa kwi-asidi yesulfuric egxininisiweyo, kwaye emva koko i-nitric acid evuthayo yongezwa nge-dropwise, kwaye ubushushu abuzange budlule kwi-50 °C. Fudumeza kwi-45 ° C nge-2h, kwaye uvuselele kwiqondo lokushisa kwe-4h. Isisombululo sokusabela sagalelwa kumkhenkce otyumkileyo, kwaye i-pH yahlengahlengiswa ukuya kwi-6 ngokudibanisa amanzi e-ammonia ngaphantsi kwe-5 ° C, kunye neekristali zatshitshiswa. Hlunga kwaye wome. Ukuhlaziya kwakhona ngamanzi ukufumana iiplatelet ezimthubi, isivuno sama-75%
I-2-Hydroxy-5-nitropyridine CAS 5418-51-9 Iikristale zeenaliti eziphuzi. Indawo yokunyibilikisa i-184-187 ° C (188-191 ° C). I-Soluble emanzini ashushu kunye nesisombululo se-alkaline, i-soluble kwi-soluble organic solvents.
