DL Methionine is a white flaky crystalline or crystalline powder. There is a special odor. The taste is slightly sweet. Melting point 281 degrees (decomposition). The pH value of a 10% aqueous solution is 5.6-6.1. It has no optical activity, is stable to heat and air, and is unstable to strong acids, which can lead to demethylation. It is soluble in water (3.3g/100ml, 25 degrees), dilute acid, and dilute solution. Extremely insoluble in ethanol and almost insoluble in ether.
