Cia thiab ceev faj
Khaws Diaminomaleonitrile CAS 1187-42-4 ntawm 0-10℃nyob rau hauv kaw amber iav nruas nyob rau hauv txias, qhuav, tsaus, deb ntawm qhib hluav taws, muaj zog oxidants, acids thiab alkalis. Hnav hnab looj tes nitrile, looj tsom iav dub thiab plua plav npog; zam kev nqus pa, tawv nqaij / qhov muag & kev noj tshuaj (tshuaj lom, irritant). Reseal nruj nreem siv los tiv thaiv oxidation; pov tseg cov khoom pov tseg raws li cov khoom siv phom sij.
Dab tsi yog qhov txiaj ntsig ntawm kev noj Diaminomaleonitrile?
✅ Muaj plaub qhov reactive nitrogen-muaj cov pab pawg ua haujlwm, ua kom muaj kev ua haujlwm siab -kev ua haujlwm cyclization rau heterocyclic compound synthesis.
✅ Zoo Diaminomaleonitrile CAS 1187-42-4 solubility nyob rau hauv polar solvents, ua kom yooj yim cov tshuaj tiv thaiv nyob rau hauv me me yam tsis muaj hnyav catalysts.
✅ Muaj-qib siab purity nrog ruaj khov batch zoo, ua raws li REACH cov qauv, haum rau lab R&D thiab loj - teev raug.
