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).
Believe Chemical ndi mtsogoleri waku ChinaNicotinamide CAS 98-92-0wopanga, wogulitsa ndi wogulitsa kunja. Kutsatira kufunafuna wangwiro khalidwe la mankhwala, kuti wathuNicotinamide CAS 98-92-0zakhutitsidwa ndi makasitomala ambiri. Shandong Khulupirirani
Ndife abwino pa ubwino wa mankhwala mankhwala m'munda. Zogulitsa zathu zimatumizidwa ku Europe, United States, Japan, South Korea, Southeast Asia ndi mayiko ena ndi zigawo. Ndi sayansi ndi luso monga kalozera, kukhulupirika monga maziko, khalidwe moyo, ndi kudalira lingaliro ogwira ntchito za luso ndi chitukuko, ife moona mtima tikuyembekeza kukhazikitsa kusinthanitsa ndi mgwirizano waukulu ndi makasitomala m'nyumba ndi akunja kulenga chitukuko!
