Monga akatswiri opanga, tikufuna kukupatsani apamwamba kwambiri N'-((2S,3S)-2-(Benzyloxy)pentan-3-yl)formohydrazide oxalate CAS 1887197-42-3. Ndipo tidzakupatsirani ntchito yabwino kwambiri ikatha kugulitsa komanso kutumiza munthawi yake.

Nicotinamide CAS 98-92-0 ndi singano yoyera ngati kristalo kapena ufa wa crystalline, wopanda fungo kapena wonunkhira pang'ono, wokhala ndi kukoma kowawa pang'ono. Kuchulukana kwachibale ndi 1.4, ndipo malo osungunuka ndi 129-131 ° C. 1g ya mankhwalawa imasungunuka m'madzi 1mL, 1.5mL ethanol kapena 10mL glycerol, koma osasungunuka mu ether. PH ya 10% yankho lamadzi ndi 6.5 - Chemicalbook 7.5. Ali ndi hygroscopicity yofooka. Ndiwokhazikika, osamva asidi, alkali komanso kutentha kwambiri. Ndiwokhazikika pakuwala ndi kutentha mumlengalenga wouma, ndipo nicotinic acid imapangidwa ikatenthedwa mumchere wamchere kapena acidic solution. Rat oral LD502.5-3.5g/kg, mtengo wa ADI sumapanga zinthu zapadera (ECC, 1990).

4'-Benzyloxy-2-bromopropiophenone CAS 35081-45-9 ndi yapakatikati ya ritodrine.

Mutha kukhala otsimikiza kugula 3-Chloro-4-fluoroaniline CAS 367-21-5 ku fakitale yathu. Ndife otsogola a 3-Chloro-4-fluoroaniline CAS 367-21-5 opanga ku China.3-Chloro-4-fluoroaniline CAS 367-21-5 ali ndi katundu, kutumiza mwachangu.COA, MSDS, TDS, ndi zina zambiri za 3 -Chloro-4-fluoroaniline CAS 367-21-5 ikhoza kuperekedwa.

Monga akatswiri opanga, tikufuna kukupatsani Polyvinylpyrrolidone CAS 9003-39-8 yapamwamba kwambiri. Ndipo tidzakupatsirani ntchito yabwino kwambiri ikatha kugulitsa komanso kutumiza munthawi yake.

3-Methylpicolinonitrile CAS 20970-75-6 kristalo yoyera, yosavuta kusintha mtundu ikawonekera. Mankhwalawa sasungunuka m'madzi, koma amasungunuka mu ethanol yotentha, ether, benzene ndi chloroform. Malo osungunuka 82 ~ 90 â.
