I-DL-Methionine CAS 59-51-8

I-Believe Chemical ingumkhiqizi ohamba phambili waseChina i-DL-Methionine CAS 59-51-8, umphakeli kanye nomkhiqizi wangaphandle. Ukunamathela ekuphishekeleni ikhwalithi ephelele yemikhiqizo, ukuze i-DL-Methionine CAS 59-51-8 yethu yaneliswe amakhasimende 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!

I-DL-Methionine CAS 59-51-8 Isicelo

I-DL Methionine yenza i-white flake crystal noma i-crystalline powder ngotshwala, enoshukela kancane futhi enephunga elikhethekile. Akukho ukujikeleza kokubona. Iyancibilika emanzini, i-dilute acid ne-alkali, incibilika kancane ku-95% wotshwala futhi ayincibiliki ku-ether.
