DL-Methionine CAS 59-51-8
DL Methionine yog dawb flaky crystalline lossis crystalline hmoov. Muaj cov ntxhiab tsw tshwj xeeb. Cov saj yog me ntsis qab zib. Melting point 281 degrees (decomposition). Tus nqi pH ntawm 10% aqueous tov yog 5.6-6.1. Nws tsis muaj kev ua haujlwm kho qhov muag, ruaj khov rau cua sov thiab huab cua, thiab tsis ruaj khov rau cov kua qaub muaj zog, uas tuaj yeem ua rau demethylation. Nws yog soluble hauv dej (3.3g / 100ml, 25 degrees), dilute acid, thiab dilute tov. Heev insoluble nyob rau hauv ethanol thiab yuav luag insoluble nyob rau hauv ether.
