l-methionine usage and synthesis |
chemical properties | white crystalline powder |
usage | essential aminoacid for human development. hepatoprotectant; antidote (acetominophen poisoning); urinary acidifier. |
general description | minute hexagonal plates from dilute alcohol. |
air & water reactions | reacts with water, steam, and/or acids to produce toxic and flammable vapors of hydrogen sulfide . water soluble . ph of 1% aqueous solution is 5.6-6.0. |
reactivity profile | an organosulfide and amine derivative, carboxylic acid. look at reactive groups 20 (organosulfides), 7 (amines), and 3 (carboxylic acids) may give indications about reactive tendencies. l-methionine is an amino acid essential in human nutrition. |
health hazard | acute/chronic hazards: l-methionine is dangerous when heated to decomposition; it emits dangerous and highly toxic fumes. |
fire hazard | flash point data for l-methionine is not available, but l-methionine is probably combustible. |
