2-Amino-3-benzyloxypyridine CAS 24016-03-3 Heterocycle raupapa; Waikano takawaenga; Rauemi mata pararopi;
Ko te waikawa 2-Amino-5-fluorobenzoic CAS 446-08-2 he mea tino nui mo te whakahiatotanga o nga rongoa, nga patupatupatu, nga kaiwhakarite tipu tipu me nga fungicides o te momo quinoline.
2-Chloro-4-nitrobenzoic acid CAS 99-60-5 Te ngira ma, kowhai kowhai, he karaihe paura ranei. Ira whakarewa 142-143°C (139-141°C). Wairewa ki te wai wera, te waipiro me te benzene wera.
4-Amino-3-nitrobenzoic acid CAS 1588-83-6 whakamahia hei waikano takawaenga
Ko te 2-Amino-5-nitropyridine CAS 4214-76-0 ka puta mai i te waikawa o te 2-aminopyridine. I te mahana o te 50 °C, ka tapirihia te 2-aminopyridine ki te waikawa pungatara mau, katahi ka tapirihia te waikawa nitric fuming, kaore i neke ake i te 50 °C. Whakanuia i te 45°C mo te 2h, ka whakakorikori i te pāmahana rūma mo te 4h. I ringihia te wairewa tauhohenga ki roto i te hukapapa kuru, ka whakatikahia te pH ki te 6 ma te taapiri i te wai haukini i raro i te 5°C, ka tohe nga tioata. Tātarihia ka maroke. Ko te whakamaaramatanga ki te wai kia whiwhi i nga pereti kowhai kowhai, ka 75%
2-Hydroxy-5-nitropyridine CAS 5418-51-9 Kiriata ngira kowhai. Ira whakarewa 184-187°C (188-191°C). Wairewa i roto i te wai wera me te wairewa kawakore, kare e rewa i roto i nga whakarewa waro whanui.
