INicotinamide CAS 98-92-0 yikristale emhlophe enaliti okanye icrystalline powder, engenavumba okanye enevumba elincinane, enencasa ekrakra kancinane. Uxinzelelo olunxulumeneyo yi-1.4, kwaye indawo yokunyibilika yi-129-131 °C. I-1g yale mveliso i-soluble kwi-1mL yamanzi, i-1.5mL ethanol okanye i-10mL glycerol, kodwa ayinakunyibilika kwi-ether. I-pH ye-10% yesisombululo samanzi ngu-6.5 - i-Chemicalbook 7.5. Ine-hygroscopicity ebuthathaka. Izinzile, ayinyangeki kwi-asidi, i-alkali kunye nobushushu obuphezulu. Izinzile ekukhanyeni kunye nokushisa emoyeni owomileyo, kwaye i-nicotinic acid yenziwa xa ishushu kwisisombululo se-alkaline okanye esine-acidic. I-Rat yomlomo LD502.5-3.5g / kg, ixabiso le-ADI alenzi izibonelelo ezikhethekileyo (ECC, 1990).
I-Believe Chemical yi-China ehamba phambiliIIIIINicotinamide CAS 98-92-0umenzi, umthengisi kunye nomthumeli ngaphandle. Ukubambelela ekusukeleni umgangatho ogqibeleleyo weemveliso, ukuze wethuIIIIINicotinamide CAS 98-92-0ziye zaneliswa ngabathengi abaninzi. Shandong Kholwa
Silungile kwiingenelo zeemveliso zemichiza kwintsimi. Iimveliso zethu zithunyelwa eYurophu, eUnited States, Japan, South Korea, Southeast Asia nakwamanye amazwe kunye nemimandla. Ngenzululwazi kunye netekhnoloji njengesikhokelo, ukunyaniseka njengesiseko, umgangatho njengobomi, kunye nokuthembela kwingqikelelo yeshishini lokusungula izinto ezintsha kunye nophuhliso, sinethemba elinyanisekileyo lokuseka utshintshiselwano kunye nentsebenziswano ebanzi kunye nabathengi basekhaya nabangaphandle ukudala impumelelo!
