Cia thiab ceev faj
Khaws 9-Carboxyfluorene nyob rau hauv cov thawv ntim amber iav ntawm qhov kub ntawm 2–8 degree, muab tso rau hauv qhov chaw txias, qhuav thiab zoo-ventilated warehouse kom deb ntawm qhov chaw tshav ntuj ncaj qha thiab cua sov. Cais 9-Carboxyfluorene CAS 1989-33-9 los ntawm cov oxidants muaj zog thiab cov hauv paus kom tsis txhob muaj tshuaj lom neeg decomposition thiab tsis zoo.
Hnav hnab looj tes nitrile, looj tsom iav dub thiab lub tshuab nqus plua plav thaum tuav. Tsis txhob nqus plua plav thiab tiv thaiv daim tawv nqaij; yaug qhov chaw uas muaj dej txaus tam sim ntawd. Rov qab nruj nreem tom qab siv thiab pov tseg cov pov tseg raws li cov cai tswj kev phom sij hauv zos.
