2-Hydroxy-5-nitropyridine CAS 5418-51-9 ʻO nā kristal nila melemele. Ka helu hehee 184-187°C (188-191°C). Hiki ke hoʻoheheʻe ʻia i loko o ka wai wela a me ka hopena alkaline, hiki ʻole ke hoʻoheheʻe ʻia i nā mea hoʻoheheʻe kūlohelohe.
ʻO Believe Chemical kahi alakaʻi Kina 2-Hydroxy-5-nitropyridine CAS 5418-51-9 mea hana, mea hoʻolako a me ka mea hoʻopuka. Hoʻopili i ka ʻimi ʻana i ka maikaʻi o nā huahana, no laila ua māʻona kā mākou 2-Hydroxy-5-nitropyridine CAS 5418-51-9 e nā mea kūʻai aku he nui. Shandong Manaʻoʻiʻo
Maikaʻi mākou i nā pono o nā huahana kemika ma ke kula. Hoʻokuʻu ʻia kā mākou huahana i ʻEulopa, ʻAmelika Hui Pū ʻIa, Iapana, South Korea, Asia Hikina Hema a me nā ʻāina a me nā ʻāina ʻē aʻe. Me ka ʻepekema a me ka ʻenehana e like me ke alakaʻi, ʻo ka ʻoiaʻiʻo ke kumu, ka maikaʻi e like me ke ola, a me ka hilinaʻi ʻana i ka manaʻo o ka ʻoihana o ka hana hou a me ka hoʻomohala ʻana, manaʻolana mākou e hoʻokumu i nā hoʻololi a me ka launa pū ʻana me nā mea kūʻai aku a me nā mea kūʻai aku e hana i ka pōmaikaʻi!
