DL-Methionine CAS 59-51-8
ʻO DL Methionine he keʻokeʻo keʻokeʻo a i ʻole ka pauka crystalline. Aia kahi ʻala kūikawā. He ʻono iki ka ʻono. He 281 degere (decomposition). He 5.6-6.1 ka pH waiwai o kahi hoʻonā wai 10%. ʻAʻohe ona hana optical, paʻa i ka wela a me ka ea, a paʻa ʻole i nā waikawa ikaika, hiki ke alakaʻi i ka demethylation. Hiki ke hoʻoheheʻe ʻia i ka wai (3.3g/100ml, 25 degere), dilute acid, a me ka dilute solution. ʻAʻole hiki ke hoʻoheheʻe ʻia i ka ethanol a aneane hiki ʻole ke hoʻoheheʻe ʻia i ka ether.
