DL-Methionine CAS 59-51-8
DL Methionine waa budo crystalline ah oo jilicsan. Waxaa jira ur gaar ah. Dhadhanku wax yar ayuu macaan yahay. Barta dhalaalka 281 darajo (kala-bax). Qiimaha pH ee 10% xal aqueous waa 5.6-6.1. Ma laha wax dhaqdhaqaaq indhaha ah, way degan tahay kulaylka iyo hawadu, wayna degan tahay asiidh adag, taas oo keeni karta demethylation. Waxay ku milmi kartaa biyaha (3.3g/100ml, 25 darajo), aashitada milo, iyo milan Aad ayaan ugu milmayn ethanol oo ku dhawaad aan lagu milmi karin ether.
