I-Nicotinamide CAS 98-92-0 iyikristalu emhlophe efana nenaliti noma i-crystalline powder, engenaphunga noma enephunga elincane, enokunambitheka okubabayo kancane. Ukuminyana okuhlobene kungu-1.4, futhi indawo yokuncibilika ingu-129-131 °C. I-1g yalo mkhiqizo iyancibilika emanzini angu-1mL, i-ethanol engu-1.5mL noma i-10mL glycerol, kodwa ayincibiliki ku-ether. I-pH yesisombululo esinamanzi esingu-10% ngu-6.5 - Chemicalbook 7.5. Ine-hygroscopicity ebuthakathaka. Iqinile, imelana ne-asidi, i-alkali kanye nezinga lokushisa eliphezulu. Iyazinzile ekukhanyeni nasekushiseni emoyeni owomile, futhi i-nicotinic acid ikhiqizwa lapho ishiswa ngesisombululo se-alkaline noma esine-asidi. I-Rat oral LD502.5-3.5g/kg, inani le-ADI alenzi ukunikezwa okukhethekile (ECC, 1990).
I-Believe Chemical iyi-China ehamba phambiliI-I-I-I-I-Nicotinamide CAS 98-92-0umkhiqizi, umphakeli kanye nomthengisi. Ukunamathela ekuphishekeleni izinga eliphelele lemikhiqizo, ukuze yethuI-I-I-I-I-Nicotinamide CAS 98-92-0aneliseke ngamakhasimende amaningi. Shandong Kholwa
Sisebenza kahle ngezinzuzo zemikhiqizo yamakhemikhali emkhakheni. Imikhiqizo yethu ithunyelwa eYurophu, e-United States, Japan, South Korea, Southeast Asia nakwamanye amazwe nezifunda. Ngomhlahlandlela wesayensi nobuchwepheshe, ukwethembeka njengesisekelo, ikhwalithi njengempilo, nokuthembela kumqondo webhizinisi wokuqamba nokuthuthuka, sithemba ngobuqotho ukusungula ukuhwebelana nokubambisana okubanzi namakhasimende asekhaya nawakwamanye amazwe ukuze sakhe ukuchuma!

Izidakamizwa zamavithamini, ezibandakanyeka enqubweni ye-metabolic emzimbeni, ezisetshenziselwa ukuvimbela nokwelashwa kwe-pellagra nokunye ukuntuleka kwe-niacin.
Isetshenziswa emikhiqizweni yokunakekelwa kwesikhumba ukuvikela isikhumba esimahhadlahhadla, ukugcina amaseli esikhumba enempilo, futhi kukhuthaze isikhumba sibe mhlophe. Isetshenziselwa ukunakekelwa kwezinwele ukukhuthaza ukujikeleza kwegazi ekhanda, izimpande zezinwele ezinempilo, ukukhuthaza ukukhula kwezinwele nokuvimbela impandla.
Ucwaningo lwamakhemikhali ezinto eziphilayo; izingxenye zokudla okunomsoco we-tissue culture medium; Izidakamizwa zomtholampilo ziyiqembu le-vitamin B, elisetshenziselwa ukuvimbela nokwelashwa kwe-pellagra, stomatitis, glossitis nezinye izifo.
I-amide derivative ye-vitamin B3 kanye ne-PARP inhibitor
