Nicotinamide CAS 98-92-0 yog ib rab koob dawb zoo li siv lead ua los yog crystalline hmoov, tsis muaj ntxhiab los yog tsw ntxhiab me ntsis, nrog ib qho iab saj. Cov txheeb ze ntom ntom yog 1.4, thiab cov ntsiab lus melting yog 129-131 ° C. 1g ntawm cov khoom no yog soluble hauv 1mL dej, 1.5mL ethanol lossis 10mL glycerol, tab sis insoluble hauv ether. Lub pH ntawm 10% aqueous tov yog 6.5 - Tshuaj Phau Ntawv 7.5. Nws muaj hygroscopicity tsis muaj zog. Nws yog qhov ruaj khov, tiv taus acid, alkali thiab kub kub. Nws ruaj khov rau lub teeb thiab cua sov hauv huab cua qhuav, thiab nicotinic acid yog tsim thaum rhuab hauv alkaline lossis acidic tov. Rat qhov ncauj LD502.5-3.5g/kg, ADI tus nqi tsis tsim tshwj xeeb (ECC, 1990).
